Ladder-backed Woodpecker (Picoides scalaris) 7.25 inches long
Ladder-backed Woodpecker, Hereford, Arizona
This small, colorful woodpecker thrives in arid areas of the southwest, including parts of Arizona, New Mexico and Texas. Its small size enables it to live in the scrubby growth of generally dry washes, mesquite groves, and brushland. It eats mainly insects but in the winter is attracted to suet feeders as shown in the photo above. Male and female share black-and-white barred back and white cheek markings, outlined in black, but the male alone sports the red crown. The top of the head is black on the female. The pair often forages together with the male concentrating on large limbs and trunks while the female, who is smaller and has a smaller bill, searches nearby twigs and bushes. Pairs utilize a wide range of nesting sites including mesquite, willow, oak, yucca or agave, utility poles and fence posts. Both parents feed the young with insects brought to the nest. These birds are permanent residents in their range and seem to be maintaining their numbers adequately.
