Documentation: Specimen: UNSM ZM12658, 22 Apr 1890 Lancaster Co.
Taxonomy: No subspecies are recognized.
Spring: Mar 18 (Jorgensen 2012), 19, 19 <<<>>> Jun 12, 12, 13
Earlier dates are 14 Mar 2011 Hall Co, 14 Mar 2016 Clay Co, 16 Mar 2011 Hall Co, and 16 Mar 2015 Phelps Co.
Later dates in Jun are likely one-year-old birds that migrate north somewhat later than adults (Farmer et al 2020). Some later Jun records are of injured birds, such as an adult at Harlan Co Reservoir, Harlan Co 20 Jun 2004. One of the late dates above is a specimen, UNSM ZM12663, collected in Lancaster Co 12 Jun 1910.
Additional later Jun and early Jul dates are 15-24 Jun 2014 Seward Co, 15 Jun 2019 Clay Co, 19 and 24 Jun 2005 (4-5) eastern Rainwater Basin (Jorgensen 2012), 21 Jun 2014 York Co, 21 Jun 2017 Lancaster Co, 23 Jun 2017 Saunders Co, 23 Jun 2017 Lancaster Co, two on 24 Jun 2001 eastern Rainwater Basin, two on 24 Jun 2014 Tamora WPA, Seward Co, 25 Jun-2 Jul 2000 Harvard WPA, Clay Co, 30 Jun 1967 Garden Co, and 3-4 Jul 2016 Lancaster Co.
Arrival is in early Apr and peak numbers occur from the last week of Apr through the first two weeks of May. Large flocks are unusual.
Pectoral Sandpiper is increasingly rare westward; there are only about 35 reports west of Phelps Co. Rosche (1994) considered the species casual in spring and listed only two records from the Lake McConaughy region. Brown and Brown (2001) noted “a few records” 22 Apr-30 May in the Keith Co area.
Average stopover period in Nebraska during spring was 14.2 days (Farmer and Wiens 1999).
- High counts: 521 in the eastern Rainwater Basin 30 Apr 2000 (including 375 at Mallard Haven WPA, Fillmore Co), 506 there 1-3 May 1998, 400 at Conestoga Lake, Lancaster Co 20 May 2016, and 350 at Father Hupp WMA, Thayer Co 11 May 2007.
Fall: Jul 9, 10, 11 <<<>>> Nov 7, 7 (Jorgensen 2012), 8
There are later reports 10 Nov 2017 Dodge Co, 16 Nov 2015 Washington Co, 20 Nov 1976 and 21 Nov 1982 Douglas-Sarpy Cos, 20 Nov 1996 Richardson Co, and 15-22 Dec 2001 Pawnee Lake, Lancaster Co (Brogie 2003). A specimen, UNSM ZM12664, was collected 4 Nov 1911 in Lancaster Co.
Adults, unusually in shorebirds, led by males, arrive in Jul, with peak numbers in late Jul, and juveniles peak in mid- to late Aug. There is a gradual decrease in numbers during Sep and Oct, but only about 10 reports for Nov. There are considerably more reports from the west during fall than in spring.
