Nijmegen





James River Bridge







All of a sudden the view was obstructed by the head of Elizabeth in front of the cam. Very upclose and personal indeed. What an unexpected surprise to be able to see her so closeby.
So it is a catch , it lasted very short.

Harrisburg: 4 eyases







Yesterday 3 eyases hatched, and this morning there where 4 little white chicklets in the scrape. One more egg to go.

Watch the video of a feeding of today!

De Mortel





Cobb Island











The eyases are laying flat out. Well don't worry they are not sick. The temp is up.
Today in Virginia it was 80 F ( 27 C). That's real warm.
Birds have no sweat glands so evaporation, one way to lose heat, can occur only via respiratory system. So they start panting. The eyases lay flat with their legs stretched. In that way they increase the amount of skin that has no feathers on it. And can cool off.
In the winter peregrines for instance withdraw one foot into their plumage to reduce heat loss and for the same reason they tuck head & neck under their wing to reduce heat loss.

So in live streaming webcams it looks very disturbing, those little babies panting and laying there like their very sick. But it is very natural behaviour.

Indianapolis









Oberhausen: evening meal







How they grow these 3 awesome juveniles. The 2 females are together all the time, the little male is a "einzelgänger" as we say that in German. Keeping to himself.

Zwolle: 8 days old





The 3 eyases are growing like they should. Both parents take very good care of the 3 little ones. The eldest one is the most assertive one. And begs the best of the 3. It's always the same, the eldest is the strongest and the most assertive one. In all scrapes I'm watching this season it is the same story. Except James River Bridge, there are 2 dominant over the third one.
But peregrine parents do their utmost to feed all eyases until they stop begging.

Heidelberg: 20 days old





Time flies, these 2 are already 20 days old. Around day 20, some yellow/beige becomes visible in the patch behind the eye, and a distinct dark edge to the wings becomes visible as the flight feathers continue to grow in length beneath the layer of down.

Zurich: 2 eyases









After days of watching the behaviour of he parents I was quite convinced there had to be eyases. And today I finally saw them. On this beautiful sunny day 2 eyases appeared on the ledge. I think they are about the age of the Rome and James River Bridge eyases so about 24-25 days. What a catch. It makes my day.
