Status: Common, locally abundant, regular spring migrant statewide. Locally common regular breeder north-central, rare elsewhere. Common regular fall migrant statewide. Locally rare regular winter visitor south and east, rare casual elsewhere.
Documentation: Specimen: UNSM ZM12449, 14 Apr 1909 Cass Co.
Taxonomy: No subspecies are recognized. This species was recently moved to genus Spatula from Anas, based on genetic studies (Chesser et al 2017).
Occasionally Northern Shoveler hybridizes with Gadwall; there is one Nebraska record, a bird photographed in Clay Co 9 May 2020 (Peterson, eBird.org). This record is one of about 30 similar records in North America (eBird.org).
Spring: Feb 14, 15, 15 <<<>>> summer
Earlier dates are included under Winter (below). The first arrivals are typically in early Mar as water opens up. Numbers peak in Apr. Reports after about 10 Jun may indicate breeding.
- High counts: 3700 at North Platte SL, Lincoln Co 2 May 2004, 3300 at Harvard and Massie WPAs, Clay Co 9 Apr 2000, and 3000 at Carter Lake, Omaha 10 Apr 2014.
Summer: Breeding may occur throughout the state (Ducey 1988), but most are found in the Sandhills and fewest in the south and east. It is a rare breeder in the Rainwater Basin (Jorgensen 2012); Evans and Wolfe (1967) only located five Northern Shoveler nests out of 206 duck nests 1958-1962, and Harding (1986) found only eight nests out of 723 total duck nests in Clay Co 1981-85. The few recent reports of breeding in the Rainwater Basin are of a brood in 1999, two broods in 2001, broods in Seward Co 16 Jul 2005 and 20 May 2007, and hen flushed off a nest at Krause WPA, Fillmore Co 31 May 2019 (Jorgensen and Brenner 2019).
- Breeding phenology:
Eggs/Incubation: 2-18 Jun.
Dependent fledglings: 20 May- 20 Jul.
Fall: summer <<<>>> Jan 7, 7, 8
Individuals and small groups may undertake short distance movements ahead of primary migration and appear away from breeding areas by late summer. Males generally leave nesting sites to molt in groups nearby in late Jun and Jul (Baldassarre 2014); a flock of 29 near North Platte, Lincoln Co 19 Jun 2012 contained nine molting males undergoing pre-alternate molt into “eclipse” plumage (Howell 2010) and 20 females and juveniles.
Primary migration commences in Sep and the species becomes more common and widespread; peak numbers are attained in mid- to late Oct. Numbers decline in Nov, but later reports are common, such as the 204 on 14 Dec 2002 in Scotts Bluff Co, and 56 at Harlan Co Reservoir, Harlan Co 18 Dec 1998.
- High counts: 2000 at North Platte SL 8 Oct 1996, “thousands” there 11 Oct 2005, 1700 there 8 Dec 1999, and 1500 at Rat and Beaver Lake WMA, Cherry Co 10 Nov 2019.
Winter: Overwintering occurs most often in the North Platte River Valley, notably in Scotts Bluff and Lincoln Cos, but there are also multiple reports of overwintering at Alma, Harlan Co, including 76 there 5 Feb 2000, and in the southeast, notably at Carter Lake, Douglas Co, where up to 400 wintered in the years 2011-2016. One wintered with Mallards at Jackson, Dakota Co 1995-96. Mid-winter records are widespread and increasing in the late 2010s in the south and east. The only mid-winter record elsewhere is the 17 on 17 Jan 2000 in Sioux and Dawes Cos.
