Falco deiroleucus has a range covering much of Latin America. The most northerly limit of its distribution is in southern
Mexico. In 1992, a total of 10 pairs were known from
Belize and Tikal National Park,
Guatemala. The species is known from throughout southern Central America, through
El Salvador,
Honduras,
Nicaragua,
Costa Rica and
Panama to
Colombia, where it is very rare (del Hoyo
et al. 1994). From there, its range extends eastwards through
Venezuela, where it is considered scarce and local with most known pairs in remote locations (Hilty 2003, Restall
et al. 2006). In
Guyana and
Suriname it is also scarce, and likewise in
French Guiana, although here it is at least widespread. It is scarce in
Trinidad and Tobago, with no records from the latter island
. It is rare in
Ecuador, and is also known to range through
Brazil and
Bolivia to
Paraguay, north
Argentina (del Hoyo
et al. 1994, Restall
et al. 2006), and was recorded for the first time in
Chile, at Calama, in 2007 (Jara 2008). Declines in territory occupancy, average annual fledgling production per pair and the overall breeding productivity of the population were noted between 1992-1997 and 2003-2009 in Belize (Berry
et al. 2010), and these declines continue (R. B. Berry
in litt. 2011). The small population (c.30 pairs) in Belize and Guatemala appears to be isolated (Berry
et al. 2010, R. B. Berry
in litt. 2011), and an analysis of historical and contemporary records suggests that the species has been extirpated from much of Central America and southern Mexico, and that its range is contracting in South America (Berry
et al. 2010). The species is thus suspected to have declined overall, owing primarily to continued habitat loss and fragmentation, and this negative trend is projected to continue (Bird
et al. 2011).
