The nesting range of the Black Merlin (Falco columbarius suckleyi), adapted to the temperate rain forest, has been reported as southeast Alaska (Gibson and Kessel 1997), coastal British Columbia (AOU 1957), and adjacent Washington (Wahl et al. 2005). Not all of this distribution has been documented with specimens collected in the nesting season, although some nesting individuals have been trapped and examined in Washington state (C. M. Anderson, fide C. M. White, in litt., 2013). Migrants and wintering birds have been recorded in Oregon (Marshall et al. 2003) and California (AOU 1957). Elsewhere, specimens have been reported from Arizona (Monson and Phillips 1981), New Mexico (Jewett 1944, Friedmann 1950), Colorado (Bailey 1942), Nevada (Alcorn 1943), Idaho (Burleigh 1972, Haak and Sawby 2012), Utah (Behle 1985, Haney and White 1999), Wisconsin (Friedmann 1950), and New Jersey (Capainolo and Pitocchelli 1990).
