Range Description

Micrastur plumbeus is restricted to the Pacific slope and lowlands in south-west Colombia (Choc, Valle de Cauca, Cauca and Nario) and north-west Ecuador (Esmeraldas and Pichincha). It was not recorded in Colombia in 1959-1992 but, since then, two sites in Valle de Cauca and four sites in Nario have been discovered (Wege and Long 1995, N. Gomez in litt. 1999, P. G. W. Salaman in litt. 1999, 2000, R. Strewe in litt. 1999), including four pairs studied in the c.20 km2 Ro ambi Community Nature Reserve (P. G. W. Salaman in litt. 1999, 2000). In Ecuador, from 1959-1998 there were only single records from three sites (K. S. Berg in litt. 1999,N. Krabbe in litt. 1999), but the number of known locations has been increasing considerably in recent years, and now includes at least seven sites in Esmeraldas (K. S. Berg in litt. 1999, O. Jahn in litt. 2007, P. Mena Valenzuela in litt. 2007, Jahn in press a) and two sites in Pichincha (N. Krabbe in litt. 1999, Jahn et al. 2002, Krabbe and Nilsson 2003). It is described as rare (Hilty and Brown 1986), but is likely overlooked.
