I love Ospreys – bet you can tell! Still, the anxiety rises when there are three eggs on a nest that, historically, simply cannot support that many mouths to feed. Right now the Mum at the Port Lincoln Osprey barge in Australia is incubating three eggs. In 2020, a drop in fish deliveries around day 16 of the youngest life meant that food insecurities hit the two older and much bigger siblings. Tapps was a victim of siblicide. Will 2021 be different?
So far the two adults are working like a super machine. Today Dad came in with a fish delivery for mom. She left and he incubated the eggs for a half hour. Have a look at that smooth exchange:
The 2019 female fledgling of the PLO nest has been seen and photographed at Tulka yesterday. Solly, the 2020 fledgling with the satellite tracker still seems to prefer Eba Anchorage but she has spent some crazy time at Streaky Bay again. Solly is 339 days old on 26 August Australian time.
If it has been awhile since you watched an Osprey catch a fish, have a look at this slow-motion video shot in the Scottish Highlands. Incredible. When you are watching this remember that Ospreys and Owls are the only birds whose outer toe is reversible to help them hold on to their prey. It allows them to grasp with two toes in the front. Great design.
The Ospreys that live in Australia along the coasts and the rivers are Eastern Ospreys, Pandion cristatus. Eastern Ospreys do not migrate. Their status ranges from secure to vulnerable and rare in various states of Australia.
Ospreys have a system of communication between one another that individuals, such as yourself, will recognize if you have been watching Osprey nests. There are 11 physical and visual displays that show they are resting, alarming, soliciting for food, in a defensive posture, nest protecting, under attack, or sky dancing to impress their mate. In addition to the body language Ospreys use they also have 8 sounds that they make alongside the physical signs. Those include alarming, food solicitation ranging from a very low sound to an extremely high pitched sound, a sound for guarding, being excited, screaming, and the sound during copulation. These findings were published in 1993 by Vincent Bretagnoll and Jean-Claude Thibault. The article is “Communicative Behavior in Breeding Ospreys (Pandion haliaetus): Description and Relationship of Signals to Life History.” It was published in The Auk, Volume 110, Issue 4, 1 October 1993, Pages 736–751.
The British Library and the Cornell Bird Lab have an extensive library of bird sounds that you can access. Also, just watch the birds intently on their nests in different situations. You will soon be able to recognize their different visual postures. For those working in situations that deal with Ospreys, it is essential that they learn the communication and behavioural signals of these birds. These skills would definitely have helped those reviewing Malin’s flight off the nest and, in the future, could save a bird’s life.
Blue 33 (11) has delivered Maya a nice fish for breakfast. So Maya is still here. It doesn’t mean she won’t eat and fly! We just need to wait and see.
Either White YW left Tiny Little an early fish or the silvery white object is a leftover piece of fish from last night’s late feed. Is Tiny home to eat it? and will she be in Cumbria all day?
Ooops. Looks like Tiny Little is too late!!!!!!!! Mr Crow has found a nice breakfast. Does this mean Tiny Little has started her first migration?
UPDATE: Tiny Little is still here. I didn’t get the photograph but someone else did. Yippee. Will try and chase her down today.
It is another misty morning. Aran is on his perch almost in the exact same position as he was yesterday morning.
And here is Aran with Mrs G. She remains in the UK still.
At the Dyfi nest, Telyn was last seen on 21 August at 12pm while Ystwyth was last seen on 24 August at 09:26. Dysynni and Idris were both at the nest on 25 August. Idris brought Dysynni a whopper.
Yesterday, Laddie, LM12, delivered a fish to LR2 on the nest. LR2 was 97 days old.
After a pesky crow flew around the nest, LM2 decided it was safer to take that whopper over to his favourite Birch tree to eat it. Wow, Laddie, great fish!
LR1 left for her migration on 15 August. This was only the second time in the history of this nest that a fledgling has left before the female.
Oh, it is lovely to see some of them still home. Thank you, Tiny Little! News in other news is there are now three eggs for the Collins Street Falcons! That last egg arrived at 23:53 last night. Congratulations. And last, if you follow the Loch of the Lowes Nest a wonderful surprise. A 2015 fledgling, FR2, flew over Guardbridge in Fife yesterday. They got a photo. Fantastic. A survivor! There is sad news today. The Black Stork fledglings received their names yesterday. 7181 (no 1) was named Julge meaning Brave. 7181 (no 2) was named Malbe meaning Sedate. 7183 (no 3) was named Tasane meaning Peaceful. You might have recalled some animal sounds being heard at the base of the nest tree. It is now confirmed, so sadly, that Malbe has been killed by an animal. Urmas has taken the body of Malbe to be examined. Word has also come that Tuul, Karl’s fledgling, has also perished. The Black Storks are so rare – it is so sad to hear of these deaths. Our hearts go out to all who loved these beautiful families and to those who so diligently worked to make sure Jan’s nestlings were fed and healthy to fledge. There has been some problems with the tracking and posting of Karl II and his fledglings locations. I will bring this to you as I locate it. Did you follow Milda? You will know that this brave White Tailed Eagle from Durbe lost her mate and sat on her eggs for eight days without food and then a potential mate came. But last year turned to be a sad year for Milda. She is now working on the nest with her new mate, Mr K. So happy for her. There is word that WBSE 28 did, finally, get some food. Send your warm and positive wishes off to all of the birds.
Correction to earlier news letter. Karl II has only had a transmitter for two years. I said ‘many’. Thank you!
Have a wonderful day everyone. Take care. See you soon.
