Population justification: The current known population includes important concentrations at Punta San Pedro (70 birds), Todos Santos (120 individuals) Santiago (up to 150 birds) and San José del Cabo (487-700 adults in 2009) (Pronatura in litt. 2009, B. Matheson in litt. 2013, R. Rodríguez-Estrella in litt. 2016). Although the total population size has not been precisely estimated, it is best placed in the band 1,000-2,499 mature individuals. This equates to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals.

Trend justification: This species is suspected to be undergoing a rapid population decline owing to pressures on Baja California's oases and the resultant conversion of habitat at many sites.
