The U.S. Congress has endorsed February as National Wild Bird Feeding Month.
Nuthatches are very acrobatic birds and are equally at home climbing headfirst up or down a tree.
Male Cardinals are the first birds to start singing in spring, sometimes as early as mid-February. Cardinals also mate for life. The Brown-Headed Cowbird has been known to throw out the eggs of other nesting birds and replace them with its own. The nesting bird, unaware of the switch, goes on to raise the cowbird's chicks. The male mockingbird may sing up to 30 different bird songs in a 10-minute period.
