Hirundo rustica erythrogaster
Status: Common regular spring and fall migrant and breeder statewide.
Documentation: Specimen: UNSM ZM6456, 27 Apr 1904 Falls City, Richardson Co.
Taxonomy: Eight subspecies are recognized (Gill and Donsker 2017), seven of which occur in Eurasia and Africa; the only subspecies breeding in North America is erythrogaster (including insularis), of Alaska, Canada, and the USA south to southern Mexico.
See Cliff Swallow for reported hybrids with that species.
Spring: Mar 28, Apr 1,2 <<<>>> summer
Arrival is in early Apr, although there are earlier reports 18 Mar 2003 Buffalo Co, 20 Mar 1972 Hall Co, 22 Mar 1976 Lincoln Co, 22 Mar 2006 Lancaster Co, and 26 Mar 1971 Brown Co. Peak numbers occur in mid-May.
- High counts: 708 in Hall Co 10 May 2003, 349 there 13 May 2006, and 302 there 11 May 2002.
Summer: Rapp et al (1958) suggested that this species was least numerous in the west, but the BBS Summer Distribution Map 2007-2013 indicates even distribution of high numbers across the state. This change is probably related to the increased numbers of buildings, bridges, and other infrastructure in previously sparsely-settled areas such as the Sandhills and Panhandle.
This species has adapted almost completely to use of human structures, with very few instances nowadays of use of traditional sites, mostly caves (Brown and Brown 2020). Brown et al (1996) stated that a nesting on a cliff at Lake McConaughy, Keith Co in 1982 which may also have been active in 1981 was “one of few natural nesting locations on the Great Plains in modern times.” BBS trend analysis show a statewide annual decline of -0.25 (95% C.I.; –0.91, 0.45), indicating populations in Nebraska are relatively stable.
- Breeding Phenology:
- At nest: 26 Apr+
- Eggs: 18 May-13 Sep (often two broods)
Nestlings: 28 Jun- 6 Sep
Fledglings: 28 Jun- 26 Jul
A pair was working on its second brood in Buffalo Co 29 Jul 2003, with hatching 2 Aug (Mollhoff 2005).
A pair in Omaha, Douglas Co had fledged three young and were starting a second brood 14 Jul 2011.
Fall: summer <<<>>> Nov 4,5,6
Numbers peak mid-Sep to early Oct. Aggregations are noticeable in late Jul; 750 were in Dixon Co 29 Jul 2019 and 260 in Saunders Co 21 Jul 2011. Fall departure is mostly complete by late Oct, although there are later reports 16 Nov 1980 Douglas-Sarpy Cos, 21 Nov 1993 Sarpy Co, and 2 Dec 1983 Howard-Hall Cos.
- High counts: 10,000 at Freeman Lakes WPA, York Co, 18 Sep 1999 (Jorgensen 2012), 3600 at Lake McConaughy 21 Sep 2000, and 3000 at Lakes North and Babcock, Platte Co 29 Sep 2011. “Thousands” in a pure flock were at Lakes North and Babcock, Platte Co, and “thousands” were at Wilkinson WMA, Platte Co, 9 Oct 2004.
