Status: Common, locally abundant, regular spring and fall migrant statewide. Accidental breeder Cherry Co. Rare casual summer visitor statewide. Uncommon regular winter visitor west, south, and east, rare casual elsewhere.
Documentation: Specimen: UNSM ZM12460, 2 Apr 1909 Cass Co.
Taxonomy: No subspecies are recognized.
An intriguing report was of an apparent hybrid at Offutt Base Lake, Sarpy Co 30 Mar 2018; its identification was uncertain, but it was likely a mix of Ring-necked Duck and Lesser Scaup, or, based on its contrasting black and white appearance, Tufted Duck and Lesser Scaup, although the bird did have a pale area on its bill suggestive of Ring-necked Duck.
Changes Since 2000: Increasing occurrence of mostly males in the Rainwater Basin late Jun-early Aug is suggestive of an establishing molt migration location. This species is rare anywhere in Nebraska in summer.
Spring: winter <<<>>> Jun 13, 13, 15
The earliest arrivals are coincident with the spring thaw; probable migrants were 12 on 30 Jan 2010 at Kearney, 12 at Boystown Lake, Douglas Co 1 Feb 2012, and 11 on 30 Jan 2016 at Lake Wanahoo, Saunders Co. Migration peaks during late Mar and early Apr, but small numbers occur into May. See Summer for later Jun reports.
- High counts: 2200 in the eastern Rainwater Basin 31 Mar 2001, 1450 at Crescent Lake NWR, Garden Co on 5 Apr 1994, 1000 at Valentine NWR, Cherry Co 29 Apr 2019, and 872 at North Platte NWR, Scotts Bluff Co on 14 Apr 1995.
Summer: There is only one recent breeding record for the state, although it was once (before 1920) a “regular historic nester” in the Sandhills (Ducey 1988). This statement appears to be based on Oberholser and McAtee (1920), who listed the species as “breeding” in June 1915 but gave no details. Today, a breeding occurrence in Nebraska would be considered extra-limital; the nearest regular breeding is currently in far northeast South Dakota (Tallman et al 2002). Thus, surprisingly, the first modern Nebraska breeding record was of a hen and brood photographed on a wetland at NNF McKelvie, Cherry Co 16 Sep 2019 (Greg Wright, personal communication; photo). A possible brood was at the same location 27-30 Jul 2020, but photos were equivocal.
Reports from locations like the Sandhills and Rainwater Basin that might be expected to host nesting birds are few but almost annual since 2000, especially in years with good water conditions. Many if not most may be one-year-old non-breeders resulting from late broods the prior year and delayed sexual maturity, and from mid-Jul molt migrants can occur. Males and unsuccessful females depart breeding locations by 15 Jul to molt in small groups in remote parts of the breeding range (Baldassarre 2014). Most late Jul Rainwater Basin reports are of males, suggestive that a few from the relatively close Minnesota breeding range might molt in Nebraska.
There are about 22 reports in the Sandhills 16 Jun-6 Sep usually of 1-2 birds, but five were at Crescent Lake NWR, Garden Co 21 Aug 2017. A surprising influx in 2005 saw a total of six males at four Rainwater Basin locations, including three at Deep Well WMA, Hamilton Co, 11 Jun-17 Jul and, in 2015, four were reported at various locations in the Rainwater Basin 27 Jun-7 Jul. A large influx occurred in 2019, with five reports of 18 birds in the Rainwater Basin. Additional Rainwater Basin records 17 Jun-Jul are of an immature in Butler Co 16 Jun-28 Aug 2020, two birds in Clay Co 26 Jun 2013, Seward Co 3 Jul 2013, Seward Co 9 Jul 2011, two in Butler Co 14 Jul 2018, and a male at Moger WPA, Clay Co, 22 Jul 2007.
The Lake McConaughy area, Keith Co may occasionally host molting males; one was at Lake Ogallala 13 Jun 2002, another on 7-12 Jun 2003, and 1-4 from 22 Jun-29 Jul 2006. The only Panhandle records 10 Jun-6 Sep are of one that may have summered at North Platte NWR in 1994, when two were noted 14 Jun and 10 Sep; one was reported in Scotts Bluff Co 10 Jun 1991, two were at Scottsbluff SL 16 Jun 2019, and a surprising 40 were at Oliver Reservoir, Kimball Co 12 Aug 2009.
There are few summer reports away from apparent suitable breeding habitat, most presumably non-breeding immatures: 9 Jun 2011 near Fremont, Dodge Co, a single at a Butler Co wetland 10 Jun, 10 Jul, and 25 Jul 2020, 11 Jun 2011 in Omaha, 20 Jun 2003 Lancaster Co, 24 Jun 2020 Dodge Co, 28 Jun 2019 Brown Co, a male was at Cunningham Lake, Douglas Co 16 Jul 2021, a male was at Salerno Marsh/N 264th St, Douglas Co through 19 Jul 2021, 24 Jul 2020 Dodge Co, 4 Aug 1990 Polk Co, 4 Aug 2006 Alma SL, 12 Aug-19 Sep 2020 Madison Co, 14 Aug 2013 Douglas Co, 15 Aug 1980 Harlan Co, 17 Aug 1981 Douglas-Sarpy Cos, 22 Aug 2018 two Chase Co, and 3 Sep 2017 Sarpy Co.
Fall: Sep 7, 7, 9 <<<>>> winter
Fall movement becomes evident during Sep, peaking generally in Oct. Good numbers often remain on larger lakes and reservoirs well into Dec; 137 were at Lake Wanahoo, Saunders Co 26 Dec 2015, 103-120 were in Scotts Bluff Co 30 Dec 2005- 2 Jan 2006, and 310 were at Lake Ogallala 30-31 Dec 2016.
- High counts: 2100 at Crescent Lake NWR 27 Sep 1995, 1228 at North Platte NWR on 10 Sep 1994, and 779 at Lake McConaughy 31 Oct.
Winter: Overwintering occurs at locations favored by other diving ducks, such as Scottsbluff SL, Scotts Bluff Co, Lake McConaughy and Lake Ogallala, Harlan Co Reservoir, and, more recently, Carter Lake, Omaha. Best mid-winter count at Scottsbluff SL is 29 on 23 Jan 2015; at Lake Ogallala 94 wintered 1999-2000 with 300 there 20 Jan, 15 wintered at Harlan Co Reservoir 1999-2000, and up to 35 at Carter Lake 2013-2014 and again in 2014-2015. Up to eight wintered at Boystown Lake, Douglas Co 2008-2009, up to four overwintered at Ta-Ha-Zouka Park, Madison Co 2019-2020, and 110 were at North Platte, Lincoln Co 2 Jan 2014.
Fewest winter reports are mid-late Jan; northerly such reports in Madison Co in 2021 were of up to 15 at Skyview Lake throughout Jan, and up to 10 at nearby Ta-Ha-Zouka Park 13-15 Jan.
