Population justification: Spatially explicit habitat models linked to density functions from surveys in 2012 predicted a population size of 17,375 birds (Oleiro and Kessler 2014). This roughly equates to 11,583 mature individuals, and thus the population size is placed in the range 10,000-19,999 mature individuals.

Trend justification: Surveys in 2014 suggested a mean change in detection rates of -73% and -16% compared to previous surveys in 1983 (Engbring et al. 1990) and 1994 (Buden 2000) respectively. The Engbring et al. (1990) surveys often appear to over-estimate numbers, so the population change is estimated at 16% decline over 20 years or 11.8% over three generations (14.4 years), which is precautionarily assumed to be ongoing.
