Status: Common regular spring migrant east, uncommon central, rare west. Uncommon regular fall migrant east and central, rare casual west.
Documentation: Specimen: UNSM ZM6808, 25 May 1901 Child’s Point, Sarpy Co.
Taxonomy: No subspecies are currently recognized (Pyle 1997).
Spring: Apr 15,17,18 <<<>>> Jun 10,10,11
Migration is from late Apr through early Jun, with peak numbers in mid-May. A very late migrant was recorded 24 Jun 2017 at Neale Woods, Douglas Co.
In the Panhandle, this species is regular but “very rare” in spring (Rosche 1994). Brown et al (1996) cited five banding records 13-29 May in the Keith Co area.
- High counts: 112 in Sarpy Co 11 May 2000, 96 in Lancaster Co 25 May 2002, 72 at Indian Cave SP, Nemaha and Richardson Cos 12 May 2000, and 55 in Wilderness Park, Lincoln, Lancaster Co 11 May
Fall: Aug 12,18,18 <<<>>> Oct 24,26,27
Migrants occur from late Aug through mid-Oct, although far fewer occur in fall than in spring. There is some evidence the fall migration routes are somewhat further east than in spring (Rimmer and McFarland 2012). Presumed failed breeders and non-breeders may disperse southward beginning in early Jul, often undergoing pre-basic fall molt while in migration (Rimmer and McFarland 2012).
There are earlier reports of one banded 25 Jul 2015 Douglas Co (Rick Schmid, pers.comm.) and 10 Aug 2012 in southeast Washington Co, and later reports 1 Nov 1971 Lancaster Co (Williams 1972) and 7 Nov 2001 Otoe Co (Falk 2002).
There are 18 Panhandle reports 1 Sep-11 Oct.
- High counts: 10 in Sarpy Co 9 Sep 1995, 5 at Wilderness Park, Lancaster Co 9 Sep 2018, and 4 at Ponca SP, Dixon Co 8 Sep 2007.
