Population justification: There were 113 territories recorded in 2009 (D. Wege in litt. 2009), hence the total population appears to number 226 mature individuals, roughly equivalent to 340 individuals in total. |
|
Trend justification: Population estimates based on yearly counts by N. Krabbe in litt. (2007) are as follows (numbers indicate occupied territories): 1999: 12-22; 2000: 15-27; 2001: 35-37; 2002: 20-35; 2003: 30-34; 2004: 42-45; 2005: 50-52; 2006: 59-61; 2007: 81-83. In 2008, there were an estimated 110-120 occupied territories (M. Juiña in litt. 2008), and in 2009 the number of occupied territories was estimated at 113 (Krabbe et al. 2010). An extremely rapid increase has occurred over the past eleven years (estimate of three generations), but the species may reach carrying capacity at around 150 pairs (N. Krabbe in litt. 2011). |
