Setophaga discolor discolor
Status: Rare casual spring migrant statewide. Accidental in summer and fall.
Documentation: Photograph: 26 May-1 Jun 1982 Niobrara Valley Preserve, Brown Co (Brogie and Mossman 1983, Bray et al 1986).
Taxonomy: Two subspecies are recognized (Pyle 1997): discolor, breeding and wintering in most of the North American range, and paludicola, resident in coastal south Florida. Nebraska birds are presumed discolor.
Spring: There are 18 reports, surprisingly scattered statewide, in the period 21 Apr-1 Jun; 12 are accepted:
30 Apr 2018 Lake McConaughy, Keith Co (https://ebird.org/view/checklist/S45128601; Brogie 2019)
6 May 2000 Carter Canyon, Scotts Bluff Co singing male (Jorgensen 2002)
7 May 1999 Wild Rose Ranch, Hall Co (Jorgensen 2001)
10 May 1979 seen singing in Jewell Park, Bellevue, Sarpy Co 21 Apr-10 May 1979 (Cortelyou 1979, Williams 1979)
11 May 2014 singing male Lancaster Co (Brogie 2015)
12 May 1996 Wilderness Park, Lincoln, Lancaster Co (Brogie 1997)
18 May 1996 Fontenelle Forest, Sarpy Co (Brogie 1997).
19 May 1974 Lincoln (Cortelyou 1974, Williams 1974)
21 May 1991 singing male Box Butte Co (Grzybowski 1991)
25 May 1978 singing male at Oshkosh, Garden Co (Rosche and Johnsgard 1984, Rosche 1994, Williams 1978)
26 May-1 Jun 1982 Niobrara Valley Preserve (cited above)
28 May 2007 Niobrara River extreme eastern Cherry Co (Silcock 2007, Gordon Warrick, personal communication, fide Wayne Mollhoff).
An additional report, probably correct, was of one singing and thought to be this species but not seen at Brady, Lincoln Co 5 May 2009; another, also heard only, was at Boyer Chute NWR, Washington Co 18 May 2018. An additional five older reports are unaccompanied by any details.
Summer: The only record is of a singing male at NNF Bessey, Thomas Co, 5 Jul 1997 (Brogie 1998).
Bruner et al (1904) cited several reports from the 19th century by Aughey and others, including two of nesting, one in Dakota Co and the other in Richardson Co, accepted by Dunn and Garrett (1997); Aughey (1878) considered it “abundant” in eastern Nebraska, and Taylor (1888) referred to it as a “Summer resident; common” in southeast Nebraska. Although some of these early reports have been questioned (Johnsgard 1979, 1980; Sharpe 1993), Wayne Mollhoff (pers. comm.) pointed out that as the forests were cleared, brushy habitat became more common, albeit often ephemeral, which would have contributed to an increase in numbers of Prairie Warbler. The existence of these old breeding records for this species and also for Blue-winged Warbler, both of which occupy similar habitat which has since largely disappeared from Nebraska, is intriguing.
Fall: There is a single documented record:
6 Sep 1998 immature male Gering Cemetery, Scotts Bluff Co (Brogie 1999).
Additional undocumented reports are 31 Aug 2002 Fontenelle Forest, 22 Sep 1983 Douglas-Sarpy Cos (Williams 1984), and 23 Sep 1972 McPherson Co.
