Behavior
===Diet===Wilson's Warbler is an insectivore, feeding primarily on insects gleaned from leaves and twigs, or caught by flycatching. Some of these insects include beetles, bees, or caterpillars. The Wilson's Warbler is an active forager, moving rapidly through shrubs, on the ground, and sometimes in taller trees during the winter. Feeding birds often twitch their tails or flick their wings nervously. The observed feeding rate of the male Wilson's warbler was not significantly different between males with or without mates. It also eats a few berries.

Famous quotes containing the word behavior:
“Growing up human is uniquely a matter of social relations rather than biology. What we learn from connections within the family takes the place of instincts that program the behavior of animals; which raises the question, how good are these connections?”
—Elizabeth Janeway (b. 1913)
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
“If parents award freedom regardless of whether their children have demonstrated an ability to handle it, children never learn to see a clear link between responsible behavior and adult privileges.”
—Melinda M. Marshall (20th century)
