Crows are found on every continent except South America and Antarctica. They are among the most intelligent and adaptable of birds, and several species have been able to thrive near humans, although others, especially on islands, are endangered and their habits little known. Many crow species are all black. Most of their natural enemies, the raptors or “falconiformes”, soar high above the trees, and hunt primarily on bright, sunny days when contrast between light and shadow is greatest. Crows take advantage of this by maneuvering themselves through the dappled shades of the trees, where their black color renders them effectively invisible to their enemies above, in order to set up complex ambush attacks.
