Status: Fairly common regular spring and fall migrant west, uncommon central, rare east. Fairly common regular breeder west, locally uncommon north-central.
Documentation: Specimen: UNSM ZM7614, 20 Mar 1900 Mullen, Hooker Co.
Taxonomy: No subspecies are recognized (Pyle 1997).
Spring: Mar 12,14,15 <<<>>> Apr 25,28,30
Migration occurs mid-Mar through mid-Apr, with an earlier report of 25 on 6 Mar 1994 in Dixon Co, and later reports 5 May 1919 Garden Co (UNSM ZM7611, collected near Oshkosh, and considered a migrant by Rosche 1994), 7 May 1980 near Valentine, Cherry Co (Cortelyou 1980), 8 May 1951 Antelope Co, 10 May 1964 Gage Co, and two on 12 May 2001 near Valentine.
Migrants are regular in the Panhandle, where they are most common in wheat stubble (Rosche 1982) but are uncommon to rare elsewhere. Easterly reports are few, although the species may be conspicuous after spring blizzards such as those of 14-15 April 1986 (Mollhoff 1986) and 10 Apr 1997. Recent easterly reports are of one near Creighton, Knox Co 7 Apr 2003 (Brogie 2004), three with Lapland Longspurs near Gretna, Sarpy Co 8 Apr 2003, 42 birds north of Blair in Washington Co 10 Apr 1997, 14 Apr 1986 Dakota Co, 14-15 Apr 1986 Douglas-Sarpy Cos (Williams 1986), 15 Apr 1985 Dakota Co, 15 Apr 1986 Pierce Co, 21 Apr 1992 during a snowstorm Douglas-Sarpy Cos, and two in “short, grassy alfalfa” in Adams Co 21 Apr 2008.
- High counts: 1045 in southwestern Kimball Co 16 Apr 1997, 500+ near Crescent Lake, Garden Co 3 May 1978 (Williams 1978), “hundreds” in the Panhandle 15 Apr 2001, and 155 in Keith Co 17 Apr.
Summer: This species primarily breeds in the northern Great Plains (Bleho et al 2015), with low densities breeding in Nebraska. BBS data (Sauer et al 2017) show a decline of > 87% throughout the species range since the 1960s; “breeding populations in Nebraska … have been much reduced” (Bleho et al 2015). Molhoff (2016) showed reports from only four BBA blocks during 2006-2011; three in Sioux County and one from Keya Paha County.
This species is most numerous in the Panhandle, where it breeds in native grasslands somewhat taller and moister than those used by McCown’s Longspur (Rosche 1982). Snyder and Bly (2009) surveyed McCown’s and Chestnut-collared Longspurs in Kimball Co in 2007 and found McCown’s to prefer heavily-grazed shortgrass prairie and bare or virtually bare cropland, with minimal overlap with Chestnut-collared nesting areas, the latter preferring lightly-grazed grassland.
The breeding range as outlined by Johnsgard (1980) extended northeastward “perhaps to Cherry County”; Youngworth (1955) reported breeding birds in northeast Cherry Co in 1932 and Ducey (1988) cited breeding season reports by Rosche eastward to pastures on the edge of the Sandhills in Cherry Co and “certain meadows” in Keya Paha Co. Two males were seen in a “historical nesting locality” in Keya Paha Co 29 May 1989 (Grzybowski 1989), and Brogie and Mossman (1983) reported three observations 11-14 May 1982, presumably in the same general area. More recently, there have been several May-Jul sightings in the Norden-Springview area of Keya Paha Co and at Hutton Sanctuary, Rock Co.
Another northeastern location is in the O’Neill area of Holt Co, where summering birds were reported a few miles northeast of O’Neill 21 May-17 Aug 1991 (Blake and Ducey 1991) and again in 1992, when 20 were seen 5 May (Grzybowski 1991). There have been several reports since those in May-Jul in Holt Co 1994-2005, including a location five miles east and 2-4 miles north of O’Neill, where “about 35” were noted 14-31 Jul 1996 (Grzybowski 1996, Silcock and Rosche 1994). One reported 17 Sep 1989 in Holt Co presumably was at the summer location there.
Away from the above locations, it may have bred near Lake McConaughy, Keith Co where an apparent family group of six was found 7 Aug 2000, and one was at NNF McKelvie, Cherry Co 19 Jun 2015.
- Breeding phenology:
Eggs: 4 Jun
Nestlings: 30 May-27 Jun
Fall: summer <<<>>> Oct 21,21,23
Departure ends by late Oct; there are later reports 29 Oct 1996 at Crescent Lake NWR, Garden Co and 8 Nov 1980 Sioux Co. There is insufficient information to determine early dates for fall migration in Nebraska, although movement of small flocks from breeding areas begins in mid-Sep (Bleho et al 2015); two were at Lake McConaughy 25 Aug 2006.
Easterly reports are fewer than in spring, the only one documented a first-winter bird photographed in Adams Co 24 Sep 2006.
- High counts: 753 in southwestern Kimball Co 13 Oct 1998, 150 at Clear Creek WMA, Keith and Garden Cos 26 Sep 1999, and 107 at Lake McConaughy 12 Oct 2000.
