Formerly known in American literature as the Sparrow hawk, this is the smallest (dove-sized) and most familiar and abundant member of the family Falconidae in North America and one of the easiest raptors to observe.
It has two considerably different plumages: adult male and female and juvenile males differ somewhat from adult males until post-juvenile mold in fall. Adult males have rufous backs and tails with blue-grey upper wing coverts. The tail has a wide black subterminal band. Juvenile males are similar to adult males but have heavily streaked breasts. Females are slightly larger than males and have reddish-brown backs and upper wing coverts that are barred with dark brown.
These birds soar with their long and pointed wings flat, and regularly hover over open and partly open country with scattered trees, including cultivated lands and occasionally suburban areas.
The American kestrel breeds statewide in open terrain from sea level to the alpine zone in the mountains.
