Status: Rare regular spring migrant east, rare casual elsewhere. Rare casual summer visitor east and central. Rare casual fall migrant east and central, accidental west.
Documentation: Specimen: UNSM ZM10813, 15 May 1888 Peru, Nemaha Co.
Taxonomy: No subspecies are recognized (Pyle 1997).

Spring: May 5, 6, 8 <<<>>> May 21, 22, 22
A later date away from likely breeding locations is 4 Jun 2005 Scotts Bluff Co.
Most of the 50 or so spring reports are from the east in late Apr-early Jun, although documented records limit the dates to those cited above, which are not known to be related to later summer occurrences of perhaps the same individuals. For such reports and for other later reports, see Summer.
There are four reports from the Panhandle, 6 May 2000 Carter Canyon, Scotts Bluff Co (Jorgensen 2002), two photographed on 8 May 2007 Scotts Bluff Co (the initial report of two birds was not accepted by NOURC, but a female photographed in the area the same day was (Brogie 2008)), 20 May 1982 Sioux Co, and 4 Jun 2005, a female, Gering Cemetery, Scotts Bluff Co. There are few other reports away from the east, most westerly of these 19 May 1993, a female netted in Keith Co (Brown et al 1996), a singing male at Lake Ogallala, Keith Co 15 May 2004, 15 May 1982 Keya Paha Co (Brogie and Mossman 1983), 17-18 May 1980 Thomas Co (Bray 1994), and 22 May 1971 Brown Co.
Considered “possibly the best total for one season”, six were reported in Sarpy Co 5-24 May 1995. Other good counts were the four on 30 Apr-21 May 2011, four on 11-30 May 2014 in the east, and four in 2015. However, sightings have declined in recent years as Golden-winged Warbler sightings have increased; no Blue-winged Warblers were reported in spring 2020.
Summer: Nebraska is at the extreme western edge of the breeding range with no confirmed breeding records for over 10 years. The only evidence for breeding is a set of eggs ascribed to this species collected in Sarpy Co in 1901 (Ducey 1988). According to Bruner et al (1904), it was a “rather common summer resident and breeder in the wooded Missouri bottoms,” said to be “present about Omaha and Peru all summer.” There are no breeding reports since that time, suggesting a significant range contraction possibly resulting from clearing of preferred habitat. It was a regular breeder in the Kansas City area until the 1940s (Robbins and Easterla 1992), and there is a small breeding population in northwest Missouri at Weston Bend SP, Platte Co, where territorial males have been present each year since about 1996, although “vegetational succession” is threatening the small population (Robbins 2018). It breeds throughout most of the southeast half of Iowa (Kent and Dinsmore 1996).
Recent Nebraska records of potential breeding are of one singing in “perfect breeding habitat” four miles south of Verdigre, Knox Co along the Verdigre Creek 8 Jun 2002 and found there again 24 May 2003 (Mark Brogie, pers. comm.), singing birds in Keya Paha Co 18 Jun 1999 and 4-19 Jun 2000 (recorded, Jorgensen 2003).
Additional summer reports in likely breeding locations are 11 Jun 1993 Sarpy Co (Grzybowski 1993), 11 Jun 1999 Fontenelle Forest, Sarpy Co, and 6 Jul 1974 Douglas-Sarpy Cos.
Fall: There are only 17 fall reports, all during 28 Aug-16 Sep, with one very late documented record 3 Oct 1982 Madison Co (eBird.org).
The only fall Panhandle report is of one 28 Aug 2016 at Chadron SP, Dawes Co, well-described by a bander from Bird Conservancy of the Rockies (not accepted by NOURC, Brogie 2017). Westerly was one 30 Aug 1970 Custer Co.
The only recent fall reports (not all documented) are 2 Sep 1994 Dakota Co, 1 Sep 2019 Lancaster Co, 7 Sep 2015 Lincoln, Lancaster Co, 9-10 Sep 1995 Dixon Co, 9 Sep 2018 Sarpy Co, 10 Sep 2018 Lancaster Co, 10 Sep 2019 Lancaster Co, 15 Sep 2011 Lancaster Co.
