Taxonomy

Taxonomic note
Pica pica, P. mauritanica, P. asirensis and P. hudsonia (del Hoyo and Collar 2016) were previously lumped as P. pica following AERC TAC (2003), AOU (1998 and supplements), Christidis and Boles (2008), Cramp et al. (1977-1994) and Sibley and Monroe (1990, 1993).

Population justification: The population size has recently been estimated at 135 pairs or fewer (270 mature individuals) (Symes et al. 2015, Babbington 2016).

Trend justification: The area is being heavily disturbed by tourism activities and climate change is bringing warmer and drier weather (Symes et al. 2015, Babbington 2016), and so the population size is inferred to be declining.
