We found this black and white bird near our front porch. When my husband went to inspect it, the bird hopped on his finger. What is it? ?— Steve and Vivian Boundy, Dwight, Illinois
George: The bird you discovered in your yard is a black and white warbler, a beautiful deep woods bird. We featured it on the cover of the Feb/Mar issue of Birds & Blooms.
This bird acts much like a nuthatch, scrambling up and down tree trunks while searching for food. It nests on the ground, typically at the base of a tree.
Males and females are much alike, though her black markings are less distinct. It is a common summer resident of Illinois. Your bird probably collided with a window and sat stunned on your porch, which is why you were able to get such a close look at it.
