Mockingbirds are found in yards and parks, roadsides, and brushy areas.


Mockingbirds eat both insects and berries.


Mockingbirds both walk and run on the ground to seek and capture insects, sometimes scanning for prey from a perch.  They also forage for berries in trees or bushes.  They frequently flash their white wing patches as a display or to frighten insects into revealing their location.


Mockingbirds breed throughout most of the U.S. from the upper Midwest south through Mexico. Their range has expanded northward in recent decades, though their population has declined somewhat in the south.

Wing Shape

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.
