Status: Common regular spring migrant east and central, rare west. Common regular fall migrant east and central, fairly common west.
Documentation: Specimen: UNSM ZM12658, 22 Apr 1890 Lancaster Co.
Taxonomy: No subspecies are recognized.
Spring: Mar 4, 8, 13 <<<>>> Jun 20, 21, 21
One of the late dates above is a specimen, UNSM ZM12663, collected in Lancaster Co 12 Jun 1910. Later reports are 4-5 on 19 and 24 Jun 2005 eastern Rainwater Basin (Jorgensen 2012), 23 Jun 2017 Saunders 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, and 30 Jun 1967 Garden Co. One-year-old birds migrate north somewhat later than adults and probably account for these later Jun records (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.
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 3, 4, 4 <<<>>> Nov 14, 14, 16
There are later reports 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.
- High counts: 1200 near Niobrara, Knox Co 27 Aug 2011, 1000 in Dakota Co 30 Jul 2011, 800 at Lakes North and Babcock, Platte Co 15 Aug 2006, and 768 at Jack Sinn WMA, Lancaster Co 16 Aug 2012.
