New Mexico is on the western edge of the Central Flyway which is one of the major migration pathways between north and south for birds traveling between breeding and wintering grounds along the Rocky Mountains. This has resulted in the state having an incredible diversity of birds with over 550 different species reported. A little more than half of this number are sighted annually on the Pajarito Plateau. Some of these birds are full-time residents, some migrate here for a few weeks or months, and other are only seen briefly as they pass through the region.

This guide features many of the birds known to frequent Los Alamos county by when they are likely to be seen in the area. You can get additional information on local birds by joining PEEC Birders or going to the eBird website. eBird also includes lists of rare bird sightings and birding hot spots.

Acorn Woodpecker

ACWO (Melanerpes formicivorus)

Family: Picidae (Woodpeckers)
Size: 8 - 9.5 in (20 - 24 cm)
Flies: Jan 01 - Dec 31

Morphology: both sexes are brownish-black with white eyes and face; the red cap on males starts at the forehead, while the one on females has a black band between it and the face

Status: native; locally common
Food source: acorns, sap, fruit and insects

Habitat: open oak/oak-pine forest

Acorn Woodpeckers are most often described as having a clown-like appearance due their brightly covered red, black and white faces. Their flight pattern is distinctive in that they will flap their wings a few times and then drop a foot. As their name implies, acorns make up the majority of their diet. The birds drill numerous holes in dead trees, telephone poles, and wooden buildings to store acorns. Such caches can be used across generations and can be riddled with thousands of holes. In contrast to other woodpeckers, while these woodpeckers eat insects, they rarely dig into wood to find them. Acorn Woodpeckers have a complicated social structure. They live in communal groups consisting of several breeding males and females. The nest consists of a cavity in a tree. Both parents as well as helpers will take turns incubating the eggs. The eggs hatch in a little less than two weeks and fledge at about a month. Parents and helpers take care of the babies.
