The most recent report of New Mexico rarities and unseasonal birds can be viewed on the eBird New Mexico Rare Bird Alert.
All individuals are encouraged to submit their observations to NMOS. This includes not only records of Review List and Sketch Details List species and species potentially new to the state, but also records of uncommon species, species of conservation concern, records documenting breeding, and early, late, or out-of-season/range birds. Details will be used for NMOS Field Notes, North American Birds, and the New Mexico Bird Records Committee. Information on how to submit sightings is available here.
For prior records of species in New Mexico, search the NMOS Field Notes online archive.
