Ervie, Jackie and Shadow at nest, Milda lays an egg…Friday in Bird World

10 March 2022

Good Morning Everyone!

The end of the week is here! It is rarely of little consequence to me unless something is happening. There are some wonderful things about retirement!

Two new to me ‘previously owned’ books arrived in the post this morning. I have been waiting some time, and what a joy to receive them. One is by Roy Dennis. It is The Loch. A Year in the Life of a Scottish Loch. It was an accompaniment to a television series in the 1990s. The images are beautiful and would have you booking a ticket to Scotland immediately. The other is a study of Peregrine Falcons in New York City by Saul Frank. It is titled City Peregrines. A Ten-Year Saga New York City Falcons. Will keep you posted!

Meanwhile, the kittens have taken over the house. They love nothing more than going in and out of a box and all the wrappings, large paper bags are fair game for an entire afternoon of jumping in and out, and anything that is light enough to be transported can and will be picked up and moved by Lewis.

Lewis decided to take over the large dog bed today with all of the blankets!

Missy fell asleep in the small basket while she was playing.

They bring joy! And they love watching the animals in the garden.

There is news of Ervie and he is still in Port Lincoln!

Lou did a marvellous job yesterday. There was a huge storm in San Francisco and Lou incubated for almost six hours was Annie was missing.

Wondering about Jackie and Shadow? They showed up together on cam 2 on Thursday. In fact, they were on the snag tree and in the nest and Shadow stayed around for some time! There is also a sub-adult hanging about.

Looking at the image above and the chart below, how old do you think this eagle is?

Jackie and Shadow were also in the nest doing some cleaning. The time was 13:38 on Thursday. Getting anxious to see if we will have a replacement clutch.

M15 was extremely busy flushing those female intruders from the territory on Wednesday, which might account for the few prey deliveries to the Es. Lady Hawk posted all the action! We might begin to imagine that M15 wishes he was less popular.

On Thursday morning, a prey drop came at 12:47. E22 got it and ate it but not before 21 had some and then 22. It went back and forth. Both ate.

I love these little chats that C F Marshburn creates for the eagles.

Wonder why there has not been a lot of prey deliveries? D Morningstar posted a very informative video of M15 and one of the female intruders. He cannot risk getting injured. Better the eaglets be a bit hungry than to have their only provider, Dad, disabled or killed.

You can hear 22 in the background calling for fish! I don’t think we will ever forget him!

Ron and Rose are approaching pip watch and now they are having to defend both their nest and those precious eggs!

I cannot think of an Osprey nest I have enjoyed more than Moorings Park. One of the reasons is Harry. Not only is he such a great provider, but he loves being in the nest with Sally and the two kids, and he is getting more involved in feeding the little ones every day.

Unlike eagles, ospreys will remove the fish from the nest to not attract insects and intruders wanting food.

The osplets eyes are open wide, as is their beak. That open beak will get the fish! The eyes of the osprey are large. Poole tells us that they can resolve the details of an object at 3-5 times the distance a human can (11).

The pair hatched on the 3rd of March. They are a week old today. These two have already tripled their body weight since hatch. This weight will double in the nest four days. Their fastest growth is between 15-30 days.

In North America, Western Ospreys, according to Cornell Bird Lab, remain in the nest for 50-55 days before their first flight (the fledge). They will return to the nest to be fed by their parents while they develop their flying skills. While the fledglings may accompany and observe the adult fishing, they are not taught to hunt/catch prey like Bald Eagles do with their fledglings. Ospreys have developed a clear instinct for knowing how to fish after 60 million years of existence.

Notice the white at the tip of the osprey looking at you in the image below. This is what remains of the egg tooth that this little one used to break up that egg shell. Also notice the black line that extends under the eye towards the nape. This helps them to ward off glare so they can see fish in the water when there is bright sun. Yes, football players picked up on this trick from the Ospreys!

These two are beginning to develop. See the cream stripe down the centre top of the back. Notice the little ‘prickles’ on either side. This pair will keep their light woolly down (feathers) for 10-12 days, and then dark charcoal thick down will replace it. This is called the ‘reptilian period’. Their heads will look like black oil has been poured on them. Some copper-red feathers will appear at the back of the head and nape. It is often during this period that osplets get ‘cranky’ and they may begin beaking one another.

There was some concern that Indigo had left the territory of his parents, Diamond and Xavier. That is not the case. He was MIA for about 24 hours, then showed up and spent an entire in the scrape. Wonder what he was up to that tired him out so much? In the Wizard of Oz we are reminded, ‘There is no place like home!’

In Latvia, Milda, the White-tailed Eagle, has laid her first egg of the 2023 season. Sending positive wishes to her and Voids. Milda deserves it. She lost her long-time mate, Ramis, two years ago. She has yet to raise chicks to fledge since then successfully. 2022 was particularly difficult. After almost starving, Milda, who had been incubating here eggs for 8 days with no food for herself, left to eat. The fear was the eggs would not hatch. But, they did. The wee things eventually froze/starved to death. So, yes, please, lots of positive wishes for this much loved WTE.

Milda will likely lay two eggs three days apart. They will be incubated for approximately 35 days.

Voldis and Milda were working on their nest and mating late in February. Arlene Beech shares some of this with us in her video.

Watching raptors incubate eggs is boring. We are almost to the stage where Ron and Rose will stop incubating and feed little eaglets! The same applies to the Venice Golf and Country Club, where osprey eggs await their pip date. There are lots of others. Meanwhile, the Kistatchie Forest eaglets are branching, and soon SW Florida will be branching also. So enjoy a few days of incubation with Annie and Lou and watching Sally and Harry feed their little ones and the two eaglets at Duke Farms. Soon you will be scrambling to find time to check in on everyone. Oh, and then Jackie and shadow could surprise us with more eggs!

It is pip watch for Martin and Rosa at Dullas-Greenaway on the 11th! – yes, tomorrow.

Watching Karl II’s Black Stork family for migration movement. Waba headed north to Eritrea, then turned around and returned to Sudan. Gosh, this little one surprises us all the time. No transmissions from Bonus, Kaia, or Karl II yet.

There has also been no transmission from Zoe from the Port Lincoln Osprey barge. We wait in hope that she will turn up somewhere and someone will see and photograph her.

I wonder how many raptors actually land on ships and travel around. We certainly saw this with Glen, the Osprey, who was on two ships. Now a Burrowing Owl has gone on a cruise.

Gosh, I hope that Zoe didn’t get on a cruise ship!

Thank you so much for joining me today. I am heading off for a wee bit of a break and to catch sight of some waterfowl, I hope. It is not clear if there will be a blog on Saturday morning. It could be an abbreviated one. I will, for sure, be back on Sunday. Take care of yourselves. See you soon.
