Catching Some Rays


I think it is pretty obvious what this bird is doing:  sunbathing.  Birds sunbathe for various reasons.  In cooler climates, it can be to warm up.  In hot climates, it is thought that sunning supports feather health, distributes Vitamin D (from the oil from the preen gland, located at the base of the tail) and even dislodges feather parasites.  Sunning can involve various body postures from fluffed up feathers, spread wings and tails with the bird angling its body for maximum sun exposure.

In the case of this Turkey Vulture (Cathartes aura), on our hill here in Gallon Jug, I think it was enjoying catching some rays and drying off after a rainy night.

Black Friday


Not that we have Black Friday here, in the sense that shoppers in the USA know it, but here are two big black vultures, side by side. More specifically, the one on the left is the black vulture (Coragyps atratus), and the red-headed one is a turkey vulture (Cathartes aura). Not unfamiliar to North Americans either since both species are widespread, especially the turkey vulture.

Here in Gallon Jug around the farm, it seems these vultures have been displaced since Hurricane Richard blew through a couple weeks ago. They were easily photographed at nearly eye level since their favorite tall roosting trees are gone.
