Status: Common regular spring and fall migrant statewide. Rare casual summer visitor north. Accidental in winter.
Documentation: Specimen: UNSM ZM7429, 17 May 1890 Lincoln, Lancaster Co.
Taxonomy: No subspecies are recognized (Pyle 1997).
Spring: Apr 9, 10, 10 <<<>>> May 31, Jun 1, 1
Migration is from mid-Apr through late May. There is an earlier report 28 Mar 2012 Kearney Co; several other Mar and early Apr reports are undocumented. There are later reports of two on 4 Jun 2013 Gordon Cemetery, Sheridan Co, 5 Jun Keith Co (Brown et al 1996), and two singing at separate locations at Scotts Bluff NM, Scotts Bluff Co 14 Jun 2019.
- High counts: 875 at Calamus Reservoir, Loup Co 7 May 2005, 750 in Rock Co 15 May 2018, 535 in Hall Co 13 May 2006, and 512 there 11 May 2002.
Summer: There is no evidence to confirm breeding in the state, despite statements to the contrary by AOU (1957, 1983) and Bent (1968). There are several statements in the literature that imply breeding, but none eliminate the possibility of confusion with Chipping Sparrow, or late spring or early fall Clay-colored Sparrow migrants. Perhaps of most interest was a report of one netted 8 Jul at Lake Ogallala, Keith Co that had a brood patch (Brown et al 1996); this date is early for a fall migrant and is plausible as a local breeder based on egg dates in North Dakota and Minnesota, which range from mid-May through late June (Winter et al 2004; Grant and Knapton 2020). There is an intriguing report of nesting near Rushville, Sheridan Co around 1956 which stated “Song, Vesper, Lark, Clay-colored, and Field Sparrows nest in the tall grass by the buildings” but also mentioned that large flocks of Chipping Sparrows were present there for three weeks in the spring at a time when Chipping Sparrow was a rare breeder in central Nebraska (Gates 1956).
Mossman and Brogie (1983) found two singing, territorial birds during the 1982 breeding season, both in Brown Co sandhills, and considered this species a “Probable nester”. Youngworth (1955) also considered this species a rare breeder in the same general area. The Mossman and Brogie sightings were 25 May and 1 Jun; the possibility of them being migrants cannot be ruled out. One was recorded in Dixon Co 12 Jun 2020 (eBird.org).
This species breeds relatively close to Nebraska in north-central and northeast South Dakota (Tallman et al 2002) and more recently in Gregory Co (north of Boyd and Keya Paha Cos in Nebraska) in south-central South Dakota (Drilling et al 2018). BBS data (Sauer et al 2017) indicate the species has recently increased in numbers. There are no documented breeding records for Wyoming (Faulkner 2010), although Dorn and Dorn (1990) reported “multiple males singing along Highway 24” on 10 Jul 1974 near Alva, Crook Co in northeast Wyoming, and two egg sets were said to have been collected near Cheyenne, Wyoming in 1889 (Faulkner 2010).
Fall: Aug 10, 11, 12 <<<>>> Nov 13, 14, 15
Migration is from mid-Aug through early Nov, peaking during Sep. Occurrence is statewide, although much larger numbers are seen in the western half of the state in fall.
Reports in mid- to late Jul are probably early migrants: 21 Jul 1975 and 23 Jul 1978 Lincoln Co and a specimen, UNSM ZM7436, taken 4 Aug 1914 at Mitchell, Scotts Bluff Co. There are later reports 22 Nov 2018 photographed Douglas Co, 23-24 Nov 2017 one photographed in Lancaster Co, 24 Nov 1968 Adams Co, 26 Nov 2004 in Otoe Co, 18 Dec 1961 Adams Co, 18 Dec 2010 Omaha CBC, and 3 Jan 2011 Hastings, Adams Co. Details provided for three on the Scottsbluff CBC 18 Dec 1976 (Cortelyou 1977) were, however, equivocal.
- High counts: 300 at West Ash Creek, Dawes Co 4 Sep 2016, “hundreds” in Lincoln and Custer Cos 27 Sep 2004, “hundreds” at Broken Bow, Custer Co 6 Sep 2008, 176 in Banner and Kimball Cos 14 Sep 2013, and 100 at Crescent Lake NWR, Garden Co 30 Aug 1998.
Winter: The only report of overwintering is of one at a feeder in extreme southeast Sioux Co Dec 2002-Feb 2003; it was netted 12 Feb and found to be healthy except that it lacked one eye (Ruth Green, personal communication). Late fall dates extending into early Jan are discussed under Fall, above.
Comments: Wayne Mollhoff provided information from notes made by L. M. Gates of a visit to Scotts Bluff Co in 1913 with Swenk in which five nests of Brewer’s Sparrows (originally thought to be Clay-colored Sparrows) were observed at the University Experiment Station Farm. There are no subsequent nesting reports from Scotts Bluff Co. Perhaps this correction might be applied to a statement by Neidrach (1932) that Clay-colored Sparrows bred in the 1930s on streams near and southeast of Pine Bluffs while Brewer’s Sparrows bred on the neighboring uplands, although the mention of both species is interesting.
