urohidrosis

foot of Monticello
Like all New World vultures, the black vulture often defecates on its own legs, using the evaporation of the water in the feces and/or urine to cool itself, a process known as urohidrosis. It cools the blood vessels in the unfeathered tarsi and feet, and causes white uric acid to streak the legs.Wikipedia

Humans like to anthropomorphize animals. In that vein, the vultures are very mannerly. They wait their turn at the table.

The grackle can also mimic the sounds of other birds or even humans, though not as precisely as the mockingbird, which is known to share its habitat in the Southeastern United States.–Wikipedia
Opportunistic omnivors. Like us.

in praise of the dead

snag in Cook forest
Standing dead trees are an important resource for the living.

But a dead tree, contrary to popular perception, has a plus side. Called a snag, it plays host to a variety of insects, fungi, spiders, and other small native creatures of the woodland; a variety of mammals, including flying and gray squirrels, raccoons, and others; and, surprisingly, about eight-five species of birds in North America. In a forest, at least, maturity and deadwood are relative terms.–Robert Halma, “The Lehigh Valley: A Natural and Environmental History”
