I am sorry to be so late in sending off my newsletter today. It was not intended and if you have worried, I apologize. The day wasn’t meant to be so busy but it simply turned out that way with a last minute trip to get 200 lbs of bird seed tacked on to the end.
Just look at these beauties. Overnight the three osplets on the Port Lincoln Barge turned into juvenile beauties. Those are serious feathers! Just look, all pushed out from their quills, perfect layering with that gorgeous white line and tip of the juvenile. Each one also seems to have grown a perfectly white beard over night. Their eyes are also that dark amber colour that will, when they are adults, turn to yellow.
Gosh. I can hardly take my eyes off of them. They are stunningly beautiful. If I could look like a bird it would seriously be a juvenile Osprey.
Mum was looking out over the water hoping that Dad was off fishing – and he was. He landed on the nest at 7:46 with a breakfish for everyone.
Little Bob, the closest to Mum’s beak and the front, is 34 days old today while the two older siblings are 36 days old. There is a ways to fledge – thank goodness, but, for now, we can enjoy how grown up they all are and how wonderful this Eastern Osprey nest has been this year. It has brought nothing but tears of joy! It goes to show how having chicks that hatch close together and plenty of food deliveries are a great combination to success.
Dr Victor Hurley heads up the research on the Melbourne Peregrine Falcons. He has been doing this for many years. He wrote a very good article about what the differences are for the two falcon nests in Australia with streaming cams – 367 Collins Street Falcons in Melbourne and Charles Sturt University in Orange and Cilla Kinross. The 367 Collins Street scrape box had 4 hatches this year while the Orange scrape box of Diamond and Xavier had one. So what is the difference to the falcons? is it better to have one or four? Dr Hurley believes for the falcons it is better to have four eyases and be run off your feet feeding them because the chance of one of them surviving to adult hood is greater than a scrape having only one chick. He believes, however, that it is beneficial to the chicks to be the ‘only One’ instead of one of four in terms of food resources. Still, others believe that the stress on the parents to feed four instead of one is immense but, we are looking at it from the chick’s perspective. Anyone watching the scrape boxes just know these growing chicks just want food!
While Dr Hurley did not address other issues, I wonder if being part of a larger hatch group helps in terms of understanding how to live in the real world where there will be pressure from others. Maybe it doesn’t matter? Last year, the male from the Collins Street scrape used to come into the nest and pluck a freshly caught pigeon. It was a terrific mess but those three girls could sure pluck a bird – and do it fast before they fledged – a skill essential to survival. Catch, pluck, eat, and go! I beg to be corrected but it seemed that Izzi had some difficulty with plucking even after an age when he should have had his own territory. So I wonder if they learn quicker and faster as part of a group??? and having plucking imprinted on them so many times?
The little eyas at Orange is 13 days old today while the Collins Street Four are starting their third week. Each is right on track in terms of development. Indeed, the little Orange eyas has been scooting around on its tarsus for a couple of days now and is very strong and healthy. – slightly ahead of the curve The plumage is changing radically on the Collins kids and they are standing and walking.
Kate St John did a wonderful blog on the developmental stages of the peregrine falcons. I want to share that with you.
Dad is trying out larger pieces of pigeon on the four. The prey came in one after another the other day. They are losing the soft down around their eyes and getting the juvenile feathers and they are also getting their wing feathers.
I am afraid that I got a little carried away with the images of Xavier and Diamond’s eyas. Not only is it loud – soon to rival Izzi – but it can also make the cutest faces.
They are all doing well. Last I checked the Bald Eagles in the United States are all still working on their nests. There is some intrigue at the Captiva Nest and the speculation as to who the male will be this season. Joe is gone and it appears Martin has been ousted also. Meanwhile, Harriet and M15 along with Samson and Gabby are steady as you go! To my knowledge there has not been a fledge at the WBSE nest in the Sydney Olympic forest but this could happen any time. And – for the lovers of Jack and Diane – it seems that the couple might be back on the Achieva Osprey nest in St Petersburg together. They have a lot of nestorations to do!
Thank you for joining me for this quick catch up. I will be shaking my head and smiling at just how beautiful three juvenile ospreys look in the PLO nest. Take care all. See you soon.
Thank you to the following for their streaming cam where I took my screen shots: Charles Sturt University at Orange Falcon Cam and Cilla Kinross, the Collins Street Falcons by Mirvac, and the Port Lincoln Osprey Project.
