Accipiter gentilis atricapillus
Status: Rare regular spring and fall migrant statewide. Rare casual summer visitor northwest. Rare regular winter visitor statewide.
Documentation: Specimen: UNSM ZM12491, Nov 1896 near Maxwell, Lincoln Co.
Taxonomy: Ten subspecies are recognized, eight of these in Eurasia, and three in the Americas: laingi of southwest Canada, atricapillus of the rest of Canada and the US, south to northwest Mexico, and apache of southwest US and northwest Mexico (Gill and Donsker 2017). Nebraska birds are atricapillus.
Spring: winter <<<>>> May 14,15,16
There are later reports in northwest Nebraska 24 May (Rosche 1982) and 1 Jun (Roger Sharpe, personal communication). Reports are most numerous late Mar and Apr. Most Nebraska birds and those few wintering to the south of Nebraska are probably young birds (see Fall). These might be expected to initiate northward movement later than mature birds, accounting for late Apr and May sightings.
Summer: Occasional observations during the summer months on the Pine Ridge probably are of wide-ranging individuals from the Black Hills of South Dakota (Roger Sharpe, personal communication, Tallman et al 2002), although, despite the presence of about 30 territories in the Black Hills 2003-2009, breeding has not been confirmed since, possibly because of the isolated location of the Black Hills hindering recruitment (Drilling et al 2018). Recent Black Hills sightings have been attributed to wandering non-breeding immatures (Drilling et al 2018). A bird suggestive of this species was seen by experienced observers over West Ash Creek, Dawes Co 15 Jun 2018. Rosche (1982) listed no summer occurrences in northwest Nebraska.
Fall: Oct 7, 8, 17 <<<>>> winter
Fledglings begin migration first, as early as late Aug and Sep (Squires and Reynolds 1997); there is a very early Nebraska report by an experienced observer of a juvenile hunting pigeons in downtown Omaha 7 Sep 2008 (Mark Brogie, pers. comm.), and another juvenile was shot near Valley, Douglas Co 17 Oct 2010. It is likely that most goshawks migrating into Nebraska are juveniles; adults tend to overwinter in their summer territories as long as food is available (Squires and Reynolds 1997).
Fall of 2019 saw four reports, more than usual. Singles were in Dixon Co 3 Nov, Lancaster Co 19 Nov, and Scotts Bluff Co 29 Nov. In addition, one was released 21 Nov by FF Raptor Recovery that had been recovered in western Nebraska a month earlier (fide JGJ). It was only the 9th goshawk handled by Raptor Recovery since 1976.
Winter: Wintering birds are mostly restricted to northern and northwestern Nebraska. Winter visitors generally defend a winter range for several weeks, such as Nebraska wintering birds remaining in the same area 9 Nov-5 Jan, 15 Nov-30 Jan, 11 Dec-26 Feb, and 3 Jan-10 Apr (Roger Sharpe, pers. comm.).
