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.

The Ospreys are returning!

It is Day 4 of World Osprey Week and there are a lot of smiles as these fish hawks return from their winter migrations.

The seasonal movement of the Western Ospreys in the United Kingdom and Western Europe happens twice a year. This means that the birds travel a total distance of 8000 km or 4970 miles annually. They migrate north in the spring where the days are long. They are returning to their nests to breed. The summer in Europe is a perfect time to raise their chicks because food is plentiful throughout the food chain. They will return to Africa from August-October, travelling alone. The mothers leave while the dads remain at the nest to feed the fledglings. Once the fledglings leave then the male will depart. They will live in the mangrove forests and estuaries of The Gambia and Senegal. The adults return to the United Kingdom between February, March, and early April while the juveniles will remain in Africa.

This seasonal migration is treacherous. It is especially difficult for the young birds. Only 30% survive their first year. Just to get to Africa they have to go through the Bay of Biscay. In the map below the Bay of Biscay is directly to the west of France. It is a huge body of water with strong winds. The Osprey have to hug the coast or they can be blown out to the Atlantic Ocean and perish.

If they make the Bay of Biscay successfully, they have three other challenges. The first is the crossing of the Mediterranean Sea. Then the Atlas Mountains in Morocco and the Sahara Desert. There is absolutely no water in the Sahara and, consequently, no fish. The trees are small and there are two major predators in the desert, the eagle owls and the jackals.

They will live in the mangroves and the estuaries of Senegal, The Gambia, with some staying in Guinea.

The new arrivals in the United Kingdom are exciting.

Laddie LM12 has been fixing up the nest at the Loch of the Lowes since 21 March hoping that NC0 will return and want to be his mate. And his wish came true. NC0 arrived back at the Scottish nest today, 25 March. But instead of bringing her a nice fish, Laddie decided that more nesting material would be appropriate. The image below shows Laddie (the one mantling) arriving once he had spotted NC0 on the nest. Shortly after they bonded their relationship – to the happy delight of thousands watching on camera!

NC0 has just arrived at the Loch of the Lowes nest in Scotland. Laddie flew to greet her with new nesting material. 25 March 2021.

Mrs G arrived at the Bywyd Glaslyn Nest in Wales at 8:42, 25 March. Her mate, Aran, should not be far behind.

Mrs G is approximately twenty to twenty-one years old. She has been nesting at Bywyd Glaslyn since 2004. She laid 32 eggs with her first mate 11 (98) and 17 eggs with Aran. Of those, 46 hatched and 41 fledged. She has at least 100 grandchildren and 4 great grand chicks. As the oldest Osprey in Wales, she is the matriarch of the Welsh Ospreys!

Dylan arrived at Lyn Clywedog in the Hafren Forest in Wales at 19:30 on 24 March. He is waiting for his mate Seren, Blue 5F to arrive.

And others are starting their journeys. Rutland 4K (13) was fitted with a satellite tracker when he was five years old during the summer of 2018. Satellite imagery indicates he left his winter home in Guinea on 21 March and is traveling at a rate of 72 kph or 45 mph.

More and more arrivals will be coming in the next few days. What a fantastic way to wind up World Osprey Week.

And checking on on the Achieva Osprey Nest in St Petersburg, Florida, I have a smile on my face. We are beginning the third day of the ‘turn around’. Gosh, I hope that I do not jinx it. It started with Diane bringing in an extra large catfish first thing on the 23rd of March. She fed the osplets for hours including Tiny Tot who had his first bursting crop for more than a week. The 24th was a good day. Crops on all during the day and this morning Jack brought in a fish with a head at 7:20:16. Tiny Tot had a nice crop! I wonder if Diane has been doing a lot of loud calling. Last night Jack landed on the nest without a fish. Diane and the three started yelling loudly – Jack took off quickly. You could almost hear Diane tell him not to come back without a fish. So the fish arrives this morning with its head – almost a first!

In the image below, Tiny Tot still has a full crop at noon on 25 March 2021.

Tiny Tot is still much smaller than his siblings but he is surviving and doing well the last few days. 25 March 2021. @Achieva Credit Union Osprey Cam

Oh, thank you for joining me on a beautiful spring day. In Manitoba, the sun is shining and the Grackle family of 17 have returned from their winter vacation. It’s a good day.

Thank you to the Loch Arkaig FB page, the Scottish Wildlife Trust, the United Kingdon Ospreys, Bywyd Glaslyn Streaming Cam, and the Achieva Credit Union for their images or streaming camera where the images were taken. Thank you to Rutland for the satellite tracking information for 4K (13).
