Population justification: The population is estimated at 19,000 mature individuals (Partners in Flight 2019).
Trend justification: This species underwent a large and statistically significant overall decrease estimated at 81% between 1970 and 2014 (Rosenberg et al. 2016), and James (1995) calculated a 23% decline in the number of clusters between the early 1980s and 1990. More recently, some large areas of Federal land have demonstrated increases in both the number of individuals and of clusters as a result of intensive management (U.S. Fish and Wildlife Service 2008, W. McDearman in litt. 2010). For example, between 1994 and 2002, populations at six military installations increased by as much as 50% (U.S. Fish and Wildlife Service 2008). As a result of conservation action, several population may currently be stable, and could be increasing overall, although some subpopulations are known to still be in decline and losing their viability (W. McDearman in litt. 2010, Sauer et al. 2017, Jackson 2020), even despite intense conservation intervention (D. Wood in litt. 2020). It has been hypothesised that there may be a time-lag between reintroduction and translocation events and the actual population growth due to the fact that groups will be small at first, but increase their reproductive rate with time (D. Wood in litt. 2020). Until the situation is clarified, an on-going slow decline is precautionarily suspected, on the basis that further cluster losses may be occurring in some subpopulations.
