As The Cobb island eyases demonstrate, they alternate between standing on their feet and resting on their tarsi.

Cobb Island








Not much of an entry today. No eyases in sight and the main camera was stuck. SO maybe tomorrow we will be able to watch them again

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.
