With short pointed wings and long narrow tails, these small falcons are well built for fast pursuit and mid-air attacks. Sexes differ in color and size, with adult males about 25 percent smaller by weight than females. Males range from blackish gray to pale blue-gray on the back with a reddish wash along sides of the breast and a banded tail; females have brownish backs.

In winter, it can be found throughout the state in open or semi-open habitats, but it is most regular near major estuaries, lakes, reservoirs, and occasionally in cities where food supplies are reliable. For nesting, Merlins use old crow, raven, hawk, or magpie nests, tree cavities, or cliff ledges. They hunt a variety of small to medium-sized birds, usually specializing in one or two locally abundant species.
