Habitat and Ecology:It inhabits dry shrubland, and breeds by direct development.

Threats [top]

Major Threat(s): The extension of Mexico City has resulted in the disappearance of most of the available suitable habitat for this species, with the result that it is now believed to be restricted to a very small protected area, the Pedregal Reserve. The Pedregal has been subject to long-term disturbance (fragmentation and isolation), and is now little more than an isolated vegetation fragment of 160 ha with no natural corridors.

Conservation Actions [top]

Conservation Actions: Survey work is urgently needed to establish the current population status of this species, subsequent to which a recovery program and strict protection of the species in the Pedregal Reserve and surroundings areas might need to be implemented. It is protected by Mexican law under the "Special Protection" category (Pr).
