Status: Rare casual statewide summer visitor.
Documentation: Photograph: 7-8 May 2012 Scottsbluff, Scotts Bluff Co (DeLara and Smith 2013).
Taxonomy: No subspecies are recognized.
Hybridization with Ruby-throated Hummingbird was studied in Oklahoma, where ranges of the two species overlap (Judd et al 2011). The following is an excerpt: “During the course of this study, 30 adult male Ruby-throated hummingbirds, 77 adult male Black-chinned hummingbirds, and 11 male hybrids were banded. A total of 118 adult male hummingbirds were banded, with 9.3% of them being apparent hybrids. Banding 11 apparent male hybrids from 2006 to 2009 suggests that hybridization between the two Archilochus species in Oklahoma is widespread. …. Black-chinned Hummingbirds appear to be expanding their range farther north, causing more frequent overlap with Ruby-throated Hummingbirds.”
A possible Nebraska hybrid is discussed in Comments.
Summer: There are six documented records.
7-8 May 2012 photographed Scottsbluff, Scotts Bluff Co photo (DeLara and Smith 2013, Brogie 2013)
29 Jun 2014, male photographed at a Lake McConaughy, Keith Co feeder 29 Jun 2014 (Brogie 2015)
8 Jul 2017 and about a month prior, photographed Blair, Washington Co (Brogie 2018)
25 Aug-21 Sep 2018 immature photographed at Croft feeders, Scotts Bluff Co (Brogie, in press)
13-16 Sep 2013 immature photographed Shelton, Buffalo Co (Brogie 2014)
18 Sep-2 Oct 2018 at Smith feeders, Scotts Bluff Co (Brogie, in press).
Prior to the first record cited above, a female Archilochus hummingbird was observed at Kimball, Kimball Co 4 Aug 1996 (Grzybowski 1997) but not identified to species. Two birds in a well-known hummingbird yard in Scotts Bluff Co 12 Aug 2016 were thought to be this species, but were not photographed. A report of one at a Lake McConaughy feeder 28 Jul 2013 was not accepted by NOURC due to insufficient detail shown in the photograph submitted. A report including video of one in a Douglas Co yard 21 Aug 2015 (see Comments) was not accepted by NOURC based on an expert opinion that the evidence did not allow conclusive identification (Brogie 2016). A report of one in a Scotts Bluff Co yard 15 Aug 2017 was not accepted by NOURC due to “lack of detail” (Brogie 2018), but was likely correct.
Comments: A videotape of what was thought to be a possible hybrid with Ruby-throated Hummingbird, taken in Omaha, Douglas Co 21-23 Aug 2015, was sent to experts Steven Mlodinow and Sheri Williamson (Justin Rink, pers, comm.). Both agreed that the bird was at least a “probable” Black-chinned Hummingbird; Williamson noted: “I see … a probable female Black-chinned. Apparent lack of a tail notch is a further point of evidence in favor of Black-chinned …; she doesn’t pump her tail when hovering between feeding bouts, but that’s not an infallible Black-chinned characteristic.” The report was judged “Not Accepted” by NOURC based on uncertainty of the identification (Brogie 2016).
An idea of the current (Fall 2015) abundance of Black-chinned Hummingbird in western Kansas comes from a veteran observer, Tom Shane: “… we finally had a nice wave of Archilochus hummingbirds arriving on 8 Sept 2015. … I am guessing we had a ratio of 70 BCHUs to 30 RTHUs. We still had 2 Black-chins and one probable Ruby-throat today 3 Oct 2015. Black-chins nested this year 30 miles west of the Kansas – Colorado line in Lamar, CO. We have not had an adult male BCHU here in Garden City in a number of years.”
