Richmond and Rosie together!

Richmond was flying around the SF Bay area and arrived at the nest to check on things and bring a piece of fish to Rosie in case she had returned from migration. That was nine days ago, just after Valentine’s Day, 16 February 2021. That is brilliant Richmond. You know she is on her way home to you.

Where’s Rosie? I have a late Valentine present.

Rosie returns landing on the nest on 18 February. It was her shortest winter migration ever. Wonder how Richmond knew to expect her? She was only away from the Whirly crane nest for 154 days. She sits resting and waiting for Richmond to find her on the nest.

Then early on the morning of 25 February 2021 magic happens. Rosie is waiting at the nest. What a beautiful view she has. The sun is just coming up.

Here comes Richmond! Hello Rosie. Did you miss me?

Here I come, Rosie.

Not sure Richmond’s grand entry was what Rosie was expecting but it is, Richmond, after all. What a crazy Osprey he is! They have been apart now for a little over five months.

If you want a warm welcome, land on the nest!

Rosie gives Richmond a flip of her wings and he pretends he is a hovercraft. Gosh the hovering that these sea eagles do is amazing. Rosie looks up at him adoringly.

You do that rather well, Richmond.

Richmond decides to take a spin around the Whirley Crane. So happy. Both are back home and ready for another season!

Bye Richmond.

Richmond is a character and he and Rosie have successfully managed an Osprey nest with three chicks to fledge several times. Incredible! But the one thing everyone loves is when Richmond brings something interesting to the nest. He is notorious for this. Once it was a blanket, then a number of stuffed toys including a monkey and another time it was an apron with a person’s name on it. In 2018, he brought a red hat to Rosie and the three chicks that everyone played with for awhile.

Richmond and Rosie are experienced parents. And again, raising a nest of three Osprey chicks is no easy feat. This is the type of rivalry that can go on and yet, the three survived to fledge. Yahoo, Richmond and Rosie!

Who’s the boss around here? Me, me, me.

Moving from San Francisco Bay and the experienced and successful nest of Richmond and Rosie to the central part of the bayou in Louisiana. This is the nest of the new couple at Kisatchie National Park. It was a busy first twenty-four hours for this young mother brooding her little one. Right around 23:29:19 a racoon tried to get up to the nest. The female was alert and she successfully defended the nest and her tiny, tiny eaglet.

An intruder is coming up the side of the nest!

Their first and only eaglet of the season hatched at 11 pm on the 23rd. It is now 36 hours old. Below is a picture of it in the big nest on the morning of the 25th. The eaglet is 34 hours old. The father has really filled the nest with food. He is a fantastic provider. The eaglet looks so little next to the fish.

So tiny in that big nest!

A challenge for this first time mother is how to feed their baby. The eaglet and the mother know by instinct that it is beak to beak. However, the mother is always either too close or the sight line for the little one is off a bit. Fish goes on its head and on the side of the face with a few bits getting into its mouth. These two need to begin to coordinate so that this little one will thrive. They are both trying – it is hard to hit a slightly moving target, the mouth of that little bobble head. Sometimes the mother tries to push the fish into the little one’s mouth. She is trying very hard. Let’s keep our fingers crossed for them. The eaglet will survive on the contents of the egg for about twenty four hours (or so I am told).

In the image below both of the parents are there caring for their wee one.

New parents adoring their day old baby.

The young mother seems to get a little frustrated when the eaglet will not open its beak wide enough. She will get the hang of it. It is hard to realize just how small the bites are these wee ones can eat!

Open wider so I can get the fish in, please!

Everyone knows what to do. They just need to meet up at the right time like Rosie and Richmond! We will keep a close watch on these two nests for developments.

Thank you for joining me. Have a fantastic day. Updates on other nests will be posted in about nine hours.

Thank you to the streaming can at the KNF Eagle Nest and the SF Bay Ospreys and the Audubon Society for the streaming cam for Richmond and Rosie.

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.

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.

Note: Ospreys carry their fish with those amazing feet and talons. Wikimedia Commons.

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:

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!
