Resumotain range in fragmented, humid, montane, pine-oak, cloud forests and older secondary growth forests, forest edges, and disturbed habitats associated with agriculture (Howell and Webb, 1995; American Omithologists' Union, 1998). There is virtually no published information on the ecology or conservation requirements of the species (Johnsgard, 1973, 1988). Data on documented populations are old, and there have been few sightings of this bird since the 1960s (Collar et al., 1992). Knowledge of its current status is based principally upon field studies conducted between 1893 and 1952 (Lowery and Newman, 1951; Davis, 1952; Leopold, 1959; Johnsgard, 1973, 1988); perhaps, fewer than 1,000 individuals exist in the wild in highly disjunct populations. Because of habitat destruction, hunting pressure, and lack of information, the World Conservation Union has listed the species as endangered with a Mace-Lande status of critical, indicating a high probability of extinction in the wild within 2 to 5 years (McGowan et al., 1995). As a component of the action plan for this species (Carroll et al., 1995; McGowan et al., 1995), we searched for its presence throughout its known range. Localities visited were choosen due to previous sightings by local people or visiting ornithologists and a geographic information map showing high, montane elevations in eastern Mexico associated
