Osprey Lessons and Sharpie pays a visit

A couple of weeks ago, a really good book landed on my desk. It is The Rutland Water Ospreys. It is beautiful, full of colour photographs, drawings, and brimming with all the information that Roy Dennis, Tim Appleton, Tim Mackrill, and Helen McIntryre learned when Rutland Water set about to increase the number of Ospreys in the United Kingdom. What they and other researchers learned through direct observation, banding, and using satellite monitored trackers has changed many commonly held beliefs about Osprey. I hope, over the course of the next weeks to introduce you to some of the things they learned, along with others.

Translocating. When Roy Dennis set about to take young osprey from their nests in Scotland and introduce them to Rutland, the team learned one big important aspect that increased their success. I mention this first because I am once again hoping there would be a break at the Achieva Osprey Nest in Dunedin, Florida. Tiny Tot has not had anything to eat since 11 am on April 11. Despite fish deliveries including a whopper by Diane, Tiny did not get that much food. How could Tiny thrive too? I wished that the rangers in Florida that work with USFWS would remove Tiny from the nest and hand feed him til he was strong enough to be introduced. And this is precisely what they did at Rutland in the beginning. What they learned is you do not remove the runt from the nest. Instead you take one of the larger, older chicks leaving the little one with its parents and possibly another sibling. By removing the bigger older chick that required more food and was being the most aggressive, the little one grew and thrived. At the same time the bigger old chick did better being translocated. It did not have to be fed by hand but could eat on its own and did not have difficulties being removed from the nest.

The image below is of the 2011 chicks of Monty and Nora from the Cors Dyfi Nest in Wales. There they are: Einion Blue DH, Dulas Blue 99, and Leri Blue DJ. They have just received their trackers. Look how the trackers fit in a little pack on their backs. [Note: 3 healthy Osprey chicks raised in the same nest. No problems with rivalry].

The satellite trackers do not harm the birds. There are various models, some are battery powered while some are solar. Many weight only 0.15 grams. They get very sophisticated and expensive depending on what data the researchers want. Some fit directly on the feathers while others are inside a kind of backpack. Using super glue, some plastic tubing, and some dental floss the tracker is fitted onto the central shaft of the tail feather if it was a tail mounted device or on the back.

Researchers check to make sure that the feathers of the young Osprey are hard-penned. When feathers begin to grow, there is blood flowing through the shaft. As the birds ready to fledge, the blood supply to the feather stops flowing and the shaft turns white. At that stage, the feather is hard penned. Some of you might remember that Joe and Connie’s oldest chick, Hope, in the Captiva Florida Bald Eagle Nest on Santibel Island died from a broken blood feather. The real cause was rodenticide but the young bird, having ingested the poison from prey she was fed, broke off one of her feathers jumping about the nest. Because the poison was an anti-coagulant, she literally bled to death. Blood feather versus hard penned.

Solly, the Port Lincoln Osprey is wearing a tracker positioned on her back that is expected to last for seven years. Others are only intended to last a year – for short term research projects. They will come off during the moult. That is the kind that the two Royal Albatross, LGL and LGK, have on their back.

Solly is 205 days old. From her backpack satellite transmitter, we know that she spent last night at Eba Anchorage. We have also learned from Solly that juvenile Eastern Osprey travel as much as 200 kilometres from their natal nest. The assumption had always been that juvenile osprey stayed closer to home. Not true!

Another common held belief was that male Ospreys always return to the area of their natal nest after their first migration to breed. The evidence this time came from banding, the coloured Darvic rings. The sighting of a male Osprey, orange/black 11 (98), a Rutland bird, in a Scots pine in north Wales, some 200 miles west of Rutland, proved that belief to be wrong. In fact, the sighting of orange/black 11 (98) in Wales did something else – it confirmed that the bird had survived. When it did not return to Rutland, it was wrongly assumed to be dead. Another sighting on that trip enroute home was of another Rutland male. This time 07 (97) was not dead either but had a female and a chick in a nest in mid-Wales.

These are only a few of the common beliefs that have been debunked through the use of logic, banding, or satellite transmitters. Every day researchers are learning something new and exciting. It is a great time to be learning about birds.

———————————————————————————-Some fun images to close off. Louis at the Loch Arkaig Osprey Nest. Instead of pacing and waiting for Aila to arrive, Louis (pronounced Lou-ee) is using his talons to dig up the nest and refurbish it. His digging is quite efficient. Everyone is holding their breath waiting for Aila to arrive.

12 April 2021. Louis is doing nestorations.

Louis continues to wait for Aila on the 13th. Oh that she would arrive. The migration is so difficult. A healthy Kielder Osprey, Blue Y6 (18) female was spotted in Santander, Spain a couple of days ago. She was healthy. Then she was found a couple of days later dehydrated and with a broken leg. All of Louis and Aila’s fans are hoping that she is in the last group of ospreys moving north from Africa into the United Kingdom.

And a glimpse at the cutes little baby osprey – the first hatch of the year in the Savannah, Georgia Osprey nest on 13 April. The pip started at 10:58 on the 12th. There are three eggs on this nest. If you want to follow this new little one and its siblings, I have posted the information below.

Sharpie must have known that I am feeling a ‘little blue’ over Tiny Tot and he decided to pay me an early morning visit. He caused quite the commotion on his arrival. There had been a glut of European Starlings at the feeders. I am not exaggerating when I say that there were no less than 35. And then we got the most beautiful murmurations – two of them – thanks to Sharpie! It is always a treat to see that Sharpie is surviving. He stays with us in the cold Canadian winter, never migrates and made a bit of history on Cornell birds because of that. Here he is today another snowy day – in April!

Thank you for joining me today – as I wait, impatiently, for Tiny Tot to be fed enough to survive. It is lovely hearing from you, too. Stay safe. Enjoy the birds!

Happy Saturday in Bird World

It might be hot and windy but Jack has delivered one big fish and another piece onto the Achieva Osprey nest this morning. Thank you, Jack! All is well on that nest! Tiny Tot still had his crop from yesterdays big feed when a big fish arrived at 7:16:50. Despite the fact that he was right there when that whopper landed, Diane pulled the fish around to feed the bigger ones first. She knows what she is doing. Feeding them first kept peace on the nest and she knew there would be enough left for her and Tiny.

Tiny Tot remained in his position when the fish arrived while the older sibs ate their breakfast. Without calling attention to himself, he pivots so that he can eat when they are finished. Very smart.

Tiny Tot is a survivor. He is clever and he keeps his eye on everything that is going on in the nest. Today, there have been no attacks on him. Did the arrival of all that fish yesterday help calm the food competition on the nest?

Tiny eats! At 9:20:03 Tiny Tot looks like he has swallowed a beach ball! Look at that crop. I just think this is the silliest pose I have ever seen in a bird. Tiny is preening his tail.

In the image below you can also get an idea of how much bigger the older sibling is than Tiny. Look at the difference in their wings. Tiny is getting his juvenile feathering on his back and wings. For sure, a total of about 7 full days without food (if you add it all up) stunted his growth. Let’s hope that these good feedings help him get bigger quicker.

Jack is working on more gold stars today. Everyone is looking up as the second food item arrives at 11:10:22. It is hard to tell but it looks like a piece of fish not a whole fish. Once again our little trooper is jolly on the spot.

This time Diane did not move the fish. She kept it by Tiny Tot and started feeding him immediately. The older ones were watching the traffic together.

At some point the older siblings came over to get a few bites. There was no bonking. Tiny had eaten a lot and he quietly turned to the rim of the nest. When they left, he turned back to mom to eat some more. Diane also ate some very good bites but before she finished the last bit, she stretched her neck to Tiny who, at first, refused any more food. In the end, he did eat a little more at 11:46:44 after mom insisting. Here he is full, Diane tidying up the tail, and a very happy nest on a hot, very windy day in St Pete’s.

In other Osprey news, Mrs G has laid her first egg of the 2021 season! Mrs G is the oldest Osprey in the United Kingdom and is the mate of the unringed male known as Aran at the Glaslyn nest in Wales. Congratulations!

And poor Dylan. The weather in the United Kingdom has been strange. It snowed on the Clywedog nest in Wales on the afternoon of 10 April. Here is that beautiful Dylan posing for us.

The mystery at the Loch Arkaig nest continues. Everyone believed that Louis had arrived the other day but it looks like it was a male intruder who is still hanging around the nest. As far as anyone knows, Louis and Aila have not returned. (I erroneously reported Louis had arrived as did everyone else!) The weather and the winds continue to be an issue and this very popular Osprey couple could be waiting it out. Meanwhile, the nice looking male looks like he owns the place.

I really wish Louis and Aila had trackers so we knew they are alright and just progressing slowly. In the satellite image below, we can see Rutland 4K (13) making his way through France on his return trip from Africa. In this 250 kilometre or 155 mile section, Rutland 4K (13) reached heights of 650 metres or 2132 feet above sea level.

These advanced backpack transmitters are amazing. They can tell you where the raptor went for their migration and if they are near to any dangerous issues such as Avian Pox along the coast of Senegal in 2021. They tell us their travel speed, the height, where they are enroute during migration. Researchers can then match this data with wind thermals. We are learning so much!

This is the most recent tracking data on Solly, the female osprey from the Port Lincoln Osprey nest. Solly is 203 days old today and she spent the night up at Eba Anchorage. Ever since she left her natal nest on the barge at Port Lincoln, Solly has been traveling north but she has continually returned, if she went much beyond Perlubie, to either Streaky Bay or Eba Anchorage. Solly has already provided the researchers in Australia with a dirth of material. We know where she spends the night, where she goes to fish, how she responds to crowds on a beach and how far away from her natal nest she went – which changed our understanding of the distance juveniles travel when they leave home.

Switching over to the United States again, it is a beautiful sunny day in Ithaca, New York and our favourite male Red-tail Hawk has been on incubation duty. In fact it is 23 degrees C and no snow in sight! Arthur, you really are a cutie. Look at that gorgeous red tail. Big Red seems to be trusting you more with nest duties.

The little eaglets born on the Minnesota DNR nest are growing. The eldest stretches its neck and watches Nancy, the female, eat the fish tail. Look at that little crop. This nest is doing really well. Everyone has learned how to feed or eat and the supply of food seems just right.

It is a good day just to pop in and check on those Great Horn Owlets, Tiger and Lily. Here is Tiger this morning standing next to Bonnie. How is that for growth? The time passed so quickly from the day the pair of owls decided to take over this Bald Eagle nest for their owlets. That was 1 February. The owlets were born on 7 and 9 March and are now 33 and 31 days old. We will see them climbing all over the nest and upon the branches soon. In a little over two weeks, around 47 days old, the owlets should be trying to fly. That should be around 24-26th of April. They will stay around the nest, improving their flying and hunting skills before dispersing to their own territory.

Thank you so much for joining me today. I hope that your Saturday is as beautiful as it is here on the Canadian prairie – gorgeous blue sky and no wind. Looking forward to 14 Celsius about the time for my walk. Take care everyone. Enjoy your weekend.

Ups and Downs in Bird World

The Scottish Osprey nests were almost blown off their platforms on Sunday. Laddie (LM12) had no more brought a fish to the nest for NC0 than the wind began to stir. You can see the choppy waves beginning on the Loch of the Lowes. Thank goodness there were no eggs in the nest! At the beginning of the migration season, Laddie arrived early in hopes that NC0 would return to his nest and be his mate. He worked daily making sure that everything was perfect for her arrival.

In the image below, NC0 has accepted Laddie’s gift of a fish. In the background you might not be able to tell the branches are blowing but you can begin to see that the water is getting choppy. Look at their fine nest and hold that image in your mind.

Now look at the image below. This is the same nest that Laddie and NC0 were standing on. There are huge waves on the loch. The trees are twisting and the winds simply picked up the part of the nest facing away from the loch and dumped it over the egg cup.

The running joke is that the situation is so dire it would make an Osprey sea sick.

Blue NC0 stands on the nest the morning after the winds, Monday 5 April. Laddie must have been disappointed after all his hard work. They are so close to needing the nest for NC0 to lay her eggs.

NC0 got busy cleaning up undaunted by the task!

Wow. NC0 worked hard and got everything back in order. And Laddie who was MIA most of the rebuilding rewarded her with a nice fish after!

Louis is expected on the Loch Arkaig Nest on 5 April to be followed by his mate, Aila. The snow and blowing winds could cause a delayed return. We will keep an eye out! Some snow remains on the nest.

In contrast Mrs G and Aran at the Bywyd Gwyllt Glaslyn Nest in Wales had a partially sunny day with no strong winds. And it wasn’t pitching down rain.

The new parent, Harry, on the Minnesota DNR Nest, stared at his eaglets for quite a long time today. Was he admiring them? was he wondering why they weren’t moving? did he think they were dead? Well, they weren’t dead. Just food comas!

The drama at the Durbes White Tailed Eagle Nest in Latvia continues. Milda and her mate, Raimis, had been together for six years when Raimis disappeared on 27 March. It is not known if he is severely injured and cannot return or if he is dead. It is a long time for him to be away from the nest. Milda is incubating three eggs and has been protecting it from a male intruder. She has gone without food to keep her precious eggs warm. The touching story of this female eagle protecting her eggs and not leaving the nest to hunt so she can eat has captured the attention of people in Latvia and around the world. She was the feature of a recent Latvian Panorama television programme. 4 April marks what would be her eighth day without food. Today, however, Milda left with the male intruder. It is not known but is assumed that she ate while she was away from the nest. She returned with a large crop. The unringed male could form a bond with Milda and feed her while she incubates her eggs. As we have learned from the nest of Spilve, a Golden Eagle, a single parent cannot forage, incubate, feed, and protect little ones alone. The next few days should clarify the situation at the nest in Kurzeme, Durbe County, in western Latvia. This is a short video of Milda flying in with the male intruder who has been named Mr. X.

Milda had her own bad weather with high winds and snow with clearing up in the late afternoon. Milda left the nest for a few minutes when the snow cleared. There is some indication that there is some fighting going on on the ground. Is it dogs? or is it Milda’s new potential mate and another male?

Some of you might be wondering what is happening at some of the other Bald Eagle nests. It is hard to keep up this time of year with Ospreys landing in the UK, eggs hatching all over the US, eggs being laid, birds coming and going and migration still on going in Manitoba. I will try and bring news of a few nests over the next few days that I have been following just to keep you up to speed.

One of those nests is The Trio over near Fulton, Illinois on the Mississippi River. There was a streaming cam on their old nest but the high winds last year destroyed it and they rebuilt. All images are from birders on the ground with their cameras. One of those is Dennis Becht. He caught this image today. If you squint you will see the head of a wee eaglet sticking up between the adults.

Solly, the Port Lincoln female Osprey, is 198 days old today. She spent Easter Sunday at Eba Anchorage and today she is back at her favourite haunts in Streaky Bay. It is wonderful to ‘see’ the satellite tracking on Solly and to know that she is well. Birders on the ground saw her with a salmon on Easter Sunday eating on a post. How grand.

Tiny Tot’s crop has gone up and then down and back up again. He had two feedings today at the Osprey Nest in St Petersburg. Jack brought in a very large fish yesterday that came and went 3 times and today, a large fish arrived at 8:02. The two older ate and Tiny Tot had a private feeding from around 8:36-9:07. He was eating again around 10:27 with the others. The regular delivery of large fish and the energy that Tiny has derived from eating plus his being clever are helping this little one to start growing and get its confidence back. Tiny hangs back and let the others eat – it protects his head and neck from bonking. But he also keeps a sharp eye on what is going on and when he senses it is nearly his time to eat, he moves up carefully without causing attention. He is extremely clever and we are all hoping that the good feedings continue. His growth is a little slowed because of so many days without food. No doubt the very large fish that have come in are working to his advantage. There is always food left for him and Diane. Gold stars for Jack.

Tiny had dropped his crop (moving food from the holding area to the stomach) this morning. There had been some concern by chatters yesterday that he might not be able to do this after he was so dehydrated from not eating for three days but, luckily that was not the case. He ate for approximately 43 minutes and then ate again. Tiny is full! And the nest is peaceful.

I wonder if Jack has found a new place to fish? The fish brought in the last two days have been much larger than some of the deliveries a few days ago.

Thank you so much for joining me today. I don’t know about the rest of you but if Tiny has a full crop in the morning my day is much brighter! Stay safe. Wish for good weather for all the birds and large fish on the Achieva Osprey nest!

World Osprey Week 22-26 March 2021

What is World Osprey Week? It is when the world joins with all our friends in the United Kingdom to celebrate the return of the Ospreys from their winter migration. It is a time for celebration, educational fun, and competitions – especially for children. There will also be a lot of videos for those of us who do not live in the UK. Congratulations to the Leicestershire and Rutland Wildlife Trust who are celebrating the 25th anniversary of Osprey Week!

Ospreys are large ‘fish hawks’. In fact, they used to be included with all species of hawk but, now, they have their own category among avians. They live near water. It can be either fresh water or salt water – rivers like the one show in the image below or coastal estuaries, lakes, reservoirs, or fish hatching ponds. You will find them anywhere there are large numbers of fish. They are known for their ability to hover, like a helicopter. They do this often when landing at their nest or when fishing where they will hover over the fish until they plunge into catch that fish – feet first!

The history of Ospreys in the United Kingdom is a sad one. By the middle of World War I (1916), they were almost extinct. The demise of the Ospreys was due to shootings and egg collecting. Later, in the twentieth century, more were dying because of pesticides like DDT. Indeed, the Ospreys were one of the first of the large birds to alert the world to the threat of these harmful chemicals. Electricity is something that each of us use daily. My laptop computer is plugged in right now recharging as I write. The lamp to my right allows me to see. But this modern convenience – electricity – is a real threat to raptors such as the Osprey. Indeed, the main threats today are loss of habitat, power line collisions, and electrocution.

Operation Jimmy honours Blue CU2 ‘Jimmy’ an Osprey born in Scotland. On his migration home, Jimmy stopped in Wales and continued to return. Jimmy was very popular. Sadly, he was electrocuted on a killer pole on a windy rainy day after he had caught his last fish. People were sad and angry. But they got to work. In an effort to stop birds from landing on these electrical poles and being killed, artificial nests started being constructed for the Osprey. In this video you can see one being installed. With the addition of natural perches, it is hoped that there will not be another electrocution.

Last year there were four breeding pairs in Wales. Today I will take a quick peek at two of those nests: Glaslyn and Dyfi. The streaming cam links are posted so you can join in the fun welcoming back these very famous Osprey.

Bywyd Gwyllt Glaslyn Wildlife (BGGW) started when the Royal Society for the Protection of Birds (RSPB) ended his stewardship program of the Glaslyn Ospreys in 2013. BGGW is a small community not-for-profit group that is dedicated to the care of the wildlife in the Glaslyn Valley including the current resident pair of Ospreys, Mrs G and Aran (since 2015).

What a gorgeous place for an Osprey nest!

Mrs G is the oldest breeding female Osprey in Wales. She has been breeding at the Glaslyn nest since 2004. She is estimated to be nineteen or twenty years old. Mrs G has laid at least fifty-one known eggs to date. Forty-one of those hatched and thirty-eight fledged. Mrs G has at least eight-five grandchildren – some have revised this figure to 100. Whew! Those are the ones they know about. What a legacy! Here is the link to their live streaming cam:

Another nest in Wales is the Dyfi Ospreys near Machynlleth. The current resident pair are Idris and Telyn and they are passionately adored by their followers. This project began in 2009 with the erection of artificial nest and perches. The first breeding pair were Monty and Nora. Nora, however, did not return from the winter migration. A new female Blue 12/10 took Nora’s place and was subsequently named Glensi. The couple fledged thirteen chicks between 2009 and including 2017. Glensi did not return to the nest in 2018. Did I say that migrating back and forth from the United Kingdom to Africa is dangerous? That spring Monty bonded with Blue 3J/13 named Telyn. Together the pair have raised six to fledge – three females and three males in the 2018 and 2019 season. Monty did not return after the 2019 season.

I love seeing Osprey catch fish to feed their little ones. Here is a look at Monty and Telyn in 2019 when there were three hungry mouths. Sadly, this will be Monty’s last clutch. He was an incredible provider:

We are related to dinosaurs, can you tell?

Here is the link to the Dyfi Osprey Project and its streaming cam:

All over the United Kingdom individuals are posting their sightings of returning Ospreys. There are currently contests at many nests to predict when the resident pair will land. One of those is Loch Arkaig and I will be taking a look at that nest tomorrow.

I have not checked in on Solly lately and it is time. Solly, the Eastern Osprey born on the barge in Port Lincoln is 172 days old today. She has been moving between the Streaky Bay area and Eba Anchorage with a couple of flights to Haslam for several weeks. Today she is back in Streaky Bay! These satellite trackers are really quite amazing.

These three images show her movements for today (the top one) and yesterday (the bottom one). This girl loves to fly around.

It is unclear if there have been any sightings of her sibling, DEW.

————————————————————————————-

Thank you so much for joining me today. Stay safe!

Thank you to the Port Lincoln Osprey Project for the satellite tracking imagery of Solly.

Hey…birds down under

The 38 day old Royal Cam chick at Taiaroa Head is having some time on its own as the ‘pre guard’ stage sets in. The parents are leaving their little one alone for various short periods. The satellite trackers on both Lime-Green-Lime (LGL, mom) and Lime-Green-Black (LGK, dad) indicate that they are fishing just off the shores of this peninsula near Dunedin, New Zealand.

LGL gave a sky call as she approached her beautiful little chick. The Royal chick had a really good feeding before LGL headed out to sea to fish.

After LGL left to go fishing around 9:30 NZ time, the little one kept itself busy playing with the nest, preening, looking around, and enjoying the sprinklers at the NZ DOC bring out to keep the chicks cool. This helps the chicks to not get stressed by the 25 degree Celsius heat (77 F).

Oh, how refreshing! Cornell Labs and NZ DOC streaming cam.

And sometimes, when you are all alone, you have to defend your nest in case a stranger walks by! As the stranger approaches, the Royal Cam chick stands alert and begins clacking its bill mimicking precisely what its parents would do.

Chick is on alert!

And here comes Henry the Heron! Henry lives on Taiaroa Head and loves to photo bomb the Royal cam chick! Sometimes Henry even does a kind of snake dance with its neck. Henry would never hurt the little chick but he does love to come for a visit to check in on the little one. We will see him often before the fledge in September.

Have I seen you before? Cornell Labs and NZ DOC streaming cam.

Where’s Solly? Solly is the 163 day old Eastern Osprey that was born on a barge in Port Lincoln. We checked in on Solly a couple of days ago and she was heading south from Eba Anchorage back to the Streaky Bay area. Well, Solly is now back in Eba Anchorage! Solly spent the night in the same marshy area as she did on her previous visit. You can see the green pin in the satellite image below. From that central point Solly has been busy going out fishing. It is always so nice to know where the birds are. These satellite trackers are quite amazing.

It is early March. The White Bellied Sea Eagles whose nest is in the forest of Sydney’s Olympic Park will not be actively undertaking nestorations for a few months but already they have come back to the nest to do some inspections. I wonder if Daisy the Duck making a deep hole for her eggs will cause them any extra work? Last night the bonded couple, Lady and Dad, spent their night sleeping on the ‘parent branch’ of the natal nest after checking out the condition of the nest earlier and making a list of what they needed to do.

The Kakapo Recovery had sad news. Uri was taken into care because he was unwell. He had lost weight and the team felt that he would improve significantly with regular food and some checkups. Uri’s blood tests looked good and he had gained weight. But Uri seriously did not like being in a building with humans. The decision was made to return him to the island and to provide supplementary feedings and check ups for him there. When the team showed up this morning to do their check up, Uri had died. Uri had no outward signs or symptoms of Aspergillosis, a fungal disease that affects Kakapo. A necroscopy will be performed to determine the precise cause of death. There are currently 205 Kakapo.

Aren’t they cute? Three little Kakapo chicks.

This is a link about the disease and the treatment that you might find interesting. The Kakapo in the video is such a sweetie as are all of these non-flying parrots. Everyone is working hard for their care and welfare.

Thank you so much for joining me today to check in on the birds that make our lives so interesting and joyful.

Everyone loves Richmond

There is a lot of chattering going on around the ‘bird’ world and the one common word that binds people in the United Kingdom with those in San Francisco and Australia is: Osprey. Every continent has Osprey – some more than others. Many of my friends adore them above any of the other feathered friends because they ‘eat fish’. They are sometimes called ‘sea eagles’ but do not confuse them with White-Bellied Sea Eagles. Totally different.

Note the beautiful yellow eye, the dark line from that eye to the neck and the hooked beak. Wikimedia Commons.

You will find Ospreys on every continent in the world except for Antarctica. And there is no missing them. They have very distinctive plumage that helps them with the glare off of the water when they are hunting. See that black line going from the beak over the eyes and to the back of the head? That will stop the glare from the water so that their great vision, three times that of a human, can help them spot the fish swimming below the surface. If you watch American football you might recall that the players put a black line under their eyes to stop glare – something learned from the Osprey! The soles of their feet are different than other raptors. They are very rough with tiny little barbs. If they were a person you might recommend they go to get a pedicure – that is how rough those soles are. That rough surface helps them to hang on to wet slippery fish that do not want to be an Osprey’s dinner. They have four toes like all other raptors but the Ospreys can do something that others can’t – they can swivel one of those front toes to the back to help hold on to those wiggly fish. Brilliant.

Ospreys are smaller than a Bald Eagle but bigger than the large hawks. They weight 1500-2000 grams (3-4 pounds). They are about 54-58 cm long (21.3-22.8 inches) with a wingspan of 150-180 cm (59 to 79 inches). Their head, throat, and body along with their legs are mostly white. They have black and white banded tail feathers and distinctive black and white wings that bend at the joint. Their beak is black and shaped like a very sharp hook. Their eyes are a beautiful, beautiful yellow.

Feet first to catch those fish! NASA image. Wikimedia Commons.

Female Osprey are about 20-30% larger than the males. The females have a ‘necklace’ of feathers that is darker and more distinctive than the male.

Osprey’s have a distinctive dive and I do not have an image of it. Once they have spotted their prey, they bring their feet forward so they are even with their beak and then catch their prey feet first. They then latch on to the fish with those sharp talons. It is quite spectacular.

How large are the fish that the Osprey catch? The Osprey normally catches fish that are 15-30 cm in length (6-12 inches) and that weight less than 454 grams or a pound. The largest observed catch was 1250 grams or 2.5 pounds. Some researchers believe that they can easily carry up to half their weight.

Do Ospreys eat anything other than fish? The answer is actually yes. While the majority of their diet is fish, Osprey have been observed, on rare occasions, to eat other birds, voles, squirrels, muskrats, eels, and salamanders. Droughts really impact Osprey and their ability to thrive.

The territory of an Osprey will be near a body of water – a lake, a river with lots of fish, along the shores of the oceans and seas. They build their nests off the ground to avoid predators. Originally, Ospreys made their nests in tall trees but, as you know, there is a shortage of structurally sound tall trees.

Those migrating to Canada have been known to make their nests on utility poles. Sadly, this is a huge problem because of electrocutions. So many died that petitions were sent to Manitoba Hydro, a public utility company. Near to Lake Winnipeg, that company began erecting nest platforms for the Osprey. Ospreys actually like human-made nests. It is said that if you provide a nest, the sea hawks will come. And many in Scotland will tell you that is true! Ospreys are loyal and generally return to the same nest year after year.

During the winter, Ospreys head to warmer climates returning to their breeding grounds in spring. Ospreys from the United Kingdom migrate to The Gambia or Senegal with some juveniles known to stay around the coastal areas of Spain. Ospreys from North America migrate to the southern parts of the United States along the Gulf of Mexico, Southern California, the coasts of Mexico and countries of Central America. Some Ospreys do not migrate. They include those living in warmer climates year round such as Australia, Singapore, other parts of Asia, and parts of the southern United States including Florida.

Solly was born on a nest sitting on a barge at Port Lincoln, Australia. She is an Eastern Osprey and they are critically endangered. Look carefully and you can see the satellite transmitter on her back. She has a bright orange band on her left leg and a metal one on the right. Solly is easy to spot and many are taking her photograph as she travels the Eyre Peninsula of Australia moving north from her barge nest. I often report on her movements and from those the researchers are changing their minds about how far Ospreys travel from their natal nest.

One of the most famous Osprey couples has their nest on a 75 foot high World War II Whirley crane in Richmond.

They are Rosie and Richmond and Richmond – well, everyone loves Richmond! Richmond is quite the character. He loves bringing blankets and stuffed toys up to the nest.

One of my most favourite Ospreys is Iris. She is not named after the flower but because she has some very distinctive spots on the iris of her left eye. Iris is the female at the Hellsgate Nest in Montana. For many, many years Iris and her mate, Stanley, nested at the site and raised many chicks. Stanley did not return in 2016. Iris’s new mate, Louis, has proven to be unreliable and the breeding seasons have been unproductive. While most Osprey are thought to live up to twenty-five years, Iris is believed to now be twenty-nine years old.

During the 2020 breeding season, Iris had simply ‘had it’. Louis, her mate, actually had another family. Iris laid her egg on the nest but Louis did not bring her food or come to relieve her. She had to leave the egg to eat – and, of course, the Ravens were watching and they came and ate it. Iris was not pleased. Then a squirrel climbed up the platform and was trying to get on the nest. Take the time to watch this video to the end. It is only four minutes long. I seriously would not mess with a female Osprey when they are having a bad day. I want to add that Iris was seen fishing and she sometimes returns to the nest. Everyone is hoping that she will come back for the 2021 season with a new partner.

Iris may help avian researchers understand how long wild Osprey can lay fertile eggs. We know that with Wandering Albatross, Wisdom, who is 69 years old is still raising chicks.

Iris is having a very bad day.

Ospreys raise only a single brood of chicks a year. There will be anywhere from one to four eggs. Both parents will incubate the eggs although many note that the female is there more than the male. The eggs are hard incubated from the time the first one is laid. This means that the last chick might hatch six days later than the first. This often results in siblicide where there are three or more chicks. The smallest is just that much smaller and seen as a threat to food resources. That said, I have seen Osprey parents do dual feedings, such as Loch Arkaig in Scotland, with three chicks growing up to fledge with no dominance issues. First pips are normally around thirty-six days. First flight dates really vary from 50 to sometimes as much as 60 days with 55 being the average. The chicks will use their natal nest as a home base. Parents will teach the juveniles to fish and will supplement them with fish they have caught for several months after fledging.

Ospreys were severely impacted by the use of DDT and their numbers declined rapidly. Many countries are working hard to reintroduce them to the wild. I highly recommend:

If you have a favourite Osprey nest, please let me know. I would love to hear about it.

Update on Solly before I leave. Solly is now 157 days old. She spent yesterday back at Eba Anchorage. Locals say she is staying in a small marshy area near the town.

Thank you so much for joining me today. Hope to see you again soon!
