Range DescriptionGeothlypis beldingi has a fragmented distribution on the Baja California peninsula, Mexico. The nominate race is known from at least 15 sites (C. Devenish in litt. 2010) with important concentrations of 70 birds at Punta San Pedro, 178-442 at Santiago (C. Devenish in litt. 2010), and 219-480 at San JosÃ© del Cabo. The race goldmani is now known from at least 12 sites including large numbers at San Ignacio (537-648 birds) and La PurÃsima (RodrÃguez-Estrella et al. 1999, Erickson et al. 2008). The population at San JosÃ© del Cabo increased in 2009 to an estimated 487-700 adults, probably related to a chance increase in the quality of habitat (Pronatura in litt. 2009). It is common at most of these sites, but the area of suitable habitat is probably very restricted (RodrÃguez-Estrella et al. 1999). It appears to have been extirpated from at least one site, El Triunfo (Erickson et al. 2008). However, in 2009 up to three adults were present at El Oro. This might be the location referred to as El Triunfo, where the species was collected in 1924 (C. Devenish in litt. 2010). Another small breeding population was recently found at Las Cuevas (Erickson et al. 2008) and San Dionisio (Pronatura in litt. 2009), near Santiago.
