Aplomado Falcon


Aplomado falcon (Falco femoralis septentrionalis)

Principal Biologist(s)

Mike Phillips

Project Location

Armendaris Ranch, New Mexico

Conservation Problem

The species has suffered a significant population decline throughout its historical range due to a variety of factors including habitat degradation and alteration (e.g., shrub encroachment and development of native grasslands).



Conservation Status

The species was listed as endangered under the Endangered Species Act in 1986.


Project Goals & Objectives

Beginning in 1997, our goal was to collaborate with The Peregrine Fund and the U.S. Fish and Wildlife Service on efforts to reintroduce falcons to restore a viable population to the Chihuahuan grasslands of the Armendaris Ranch and environs, which would count toward federal recovery of the species per the Endangered Species Act. By 2013, it was apparent that ecological circumstances precluded restoration of such a population. Therefore, that year we terminated field efforts on behalf of the species.
