Status: Common regular spring and fall migrant and breeder east and central, uncommon west.
Documentation: Specimen: UNSM ZM12811, 23 Jun 1892 Lancaster Co.
Taxonomy: No subspecies are recognized.
Spring: Mar 20, 25, 25 <<<> summer (southeast). Apr 13, 14, 17 <<<>>> summer (west).
Arrival is mainly in Apr, although earliest reports are in late Mar in the extreme southeast and late Apr in the west. There are earlier reports 7 Mar 1973 Adams Co, 10 Mar 1955 Gage Co, 15 Mar 1957 Gage Co, and 16 Mar 1956 Gage Co.
- High counts: 118 in Sarpy Co 11 May 1996, 100 over Capitol Beach Lake, Lincoln, Lancaster Co 20 May 2017, 90 at Pioneers Park, Lincoln, Lancaster Co 30 Apr 2016, and 90 Over UNL Campus, Lancaster Co 8 May 2019.
Summer: The breeding range has expanded westward since settlement by Europeans, likely due to human habitation providing nest sites (Steeves et al 2020). In the early 1900s, the species was rare away from the east (Bruner et al 1904), although Bates (1900) noted that it bred at O’Neill and Atkinson. Swenk (Notes Before 1925) cited a specimen, 2626, in the Brooking collection taken at Crescent Lake, Garden Co 18 Jun 1917, Tout (1947) listed only one record for Lincoln Co, a dead bird found while cleaning his chimney in North Platte 22 Sep 1908, and Ludlow (1935) considered it uncommon “this far west,” in Webster Co, where it was not known to summer. It first bred in Brule, Keith Co in 1957 (Huntley 1958). By 1980 it was considered rare in the Panhandle (Johnsgard 1980). Ducey (1988) cited no breeding records west of North Platte, Lincoln Co, which was the westward limit noted by Rapp et al (1958).
Currently it occurs westward throughout the North and South Platte River Valleys, having been noted around Sutherland, Lincoln Co in 1956 (Short 1961), a first-time summer resident at Brule in 1957 (Huntley 1958), and first reported as a summer resident in Scotts Bluff Co in 1966.
Rosche (1972, 1982) observed Chimney Swifts at Crawford, Dawes Co from 1972 onward; there is only a single record from the northern Panhandle prior to 1972, that of birds seen at Alliance, Box Butte Co in 1956 (Mathisen and Mathisen 1958). It is now established in towns of the southern Panhandle, notably Chappell, Sidney and Kimball. In 2005 Chimney Swifts were reported from Harrison, Sioux Co, possibly the last Panhandle town to record the species. In 2015, summer reports were from Chadron and Fort Robinson SHP in Dawes Co, and Scottsbluff, locations where the species is now established.
Most nesting now occurs in brick or masonry structures, including chimneys, but at one time this species nested in holes in trees of mature woodlands. Mollhoff (2001) observed that populations are declining as older buildings with chimneys are demolished, and natural nest sites are taken by European Starlings and Wood Ducks. Steeves et al (2020) stated, however: “Loss of nesting habitat (suitable chimneys) has often been cited as the cause of population declines but has so far proven false where investigated.”
- Breeding Phenology:
Eggs: 6-10 Jun
Fall: summer <<<>>> Sep 29, 29, 29 (west)
summer <<<>>> Oct 24, 27, 27 (south, east)
Departure is in early Oct; there is a later report 5 Nov 1990 Douglas Co. In the west, departure is in late Sep, although there is a later report 5 Oct 1996 in Lincoln Co (Grzybowski 1997). During migration large numbers may build up, especially in urban areas; 1000 were using a chimney in Omaha in late Aug (Ducey 2003). One roost site, a church chimney near downtown Omaha, was used for several weeks by hundreds, perhaps the low thousands; these were observed entering the chimney at dusk 16 Sep 1983 (Roger Sharpe, personal communication).
- High counts: 1415 at a Lincoln, Lancaster Co chimney 23 Sep 2019, 695 there 19 Sep 2018, 532+ at an Omaha chimney 7 Sep 2007, and 529 there 20 Sep 2013.
