Population justification: This species appears to have a population of fewer than 2,500 individuals, with an estimate of 400-600 individuals given by Juniper and Parr (1998), which is also cited by Berg and Angel (2006), who estimated 214 birds at one roost in south-western Ecuador. Surveys of more than 40% of the coastline of Ecuador in November 2012 and January 2014 have yielded a minimum of 304 individuals in the study area (M. Pilgrim and B. Biddle in litt. 2013, B. Biddle in litt. 2014). The population is therefore placed in the band for 1,000-2,499 individuals, assumed to equate to 670-1,674 mature individuals, rounded to c.600-1,700. The population appears to exist in multiple sub-populations that are isolated by a lack of continuous habitat, with the largest sub-population recorded in recent surveys numbering 139 individuals (B. Biddle in litt. 2014), thus it is assumed that all sub-populations number no more than 250 mature individuals.

Trend justification: There has been an apparent reduction of 18-35% in the number of birds in the Puerto Hondo Mangrove area between 2006 (Berg and Angel 2006) and 2014 (B. Biddle in litt. 2014). Overall, the population is inferred to be in decline owing to on-going habitat destruction and unsustainable levels of exploitation.
