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.

Although Pine Siskins are patterned like sparrows, their overall behavior emphasizes that they are are related to goldfinches. They actively forage for seeds in trees and shrubs and can spend all day at a thistle feeder. Pine Siskins are an irruptive species meaning that they can have an irregular migration pattern, i.e., large flocks of these birds are sometimes observed in unexpected areas. Pine Siskins may nest in loose colonies or isolated pairs. Cup-shaped nests are usually well hidden in a conifer. Incubation time is about 2 weeks with the young leaving the nest 2 weeks later.
