Population justification: Since 2009, 80-113 territories have been recorded in each year (D. Wege in litt. 2009; H. M. Schaefer in litt. 2020). The total population hence numbers 160-226 mature individuals. This is roughly equivalent to 240-340 individuals in total.
Trend justification: The number of occupied territories has been surveyed annually since 1999. 12-22 territories were counted in 1999, 15-27 territories in 2000, 35-37 territories in 2001, 20-35 territories in 2002, 30-34 territories in 2003, 42-45 territories in 2004, 50-52 territories in 2005, 59-61 territories in 2006 and 81-83 territories in 2007 (N. Krabbe in litt. 2007). In 2008, there were an estimated 110-120 occupied territories (M. JuiƱa in litt. 2008), and in 2009 the number of occupied territories was estimated at 113 (Krabbe et al. 2011). Counts of singing males found 99 in 2011, 107 in 2012 and 112 in 2013 (S. Hartmann in litt. 2014). In 2018 and 2019, 75 and 83 territories were counted respectively, albeit with lower observation effort as compared to previous years, so that the population is currently estimated at c.100 pairs (H. M. Schaefer in litt. 2020). An extremely rapid increase has occurred between 2003 and 2009, but the species has now reached carrying capacity within the Yunguilla Reserve (Hartmann et al. 2017; H. M. Schaefer in litt. 2020). Increases beyond the current population size are limited by habitat availability (H. M. Schaefer in litt. 2020).
