The Green Ibis is a large bird with a peculiar bill that almost looks like a sickle. The name is misleading, as most of the time this bird is found perched high in the trees early in the morning, so the lighting conditions make it look black. If you pay close attention, there is some green iridescence in the neck, and the body does look greenish, however most of the time it will resemble a Black Vulture. Their noisy call is only heard when they are flying from one tree to another one. They do come to the ground for feeding, but at the first sign of potential danger, they will fly off to safety high in a tree.
