Some birds, due to their cryptic or furtive nature, present great challenges to the birder. Frequently you need to sort many separate and incomplete clues to come up with the proper identification. The birder doesn't always get a good long look at the bird. Sometimes much of the bird s body is hidden behind foliage or it is flying away. Many times the light is terrible, or the bird continues to disappear from view.
Birds have amazing and varied behaviors.
Some things birds do naturally beg the question why are they doing this. Anting, pecking at their image in a car mirror or a window, preening activities, courtship displays, aggressive displays, hurt-wing displays. Around the second half of April each year, during Texas' amazing spring migration, Texas Parks and Wildlife and Texas Partners in Flight sponsor the Great Texas Birding Classic.
