BLACK-CHINNED HUMMINGBIRD

Archilochus alexandri

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.

SummerThere are five 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)

15 Aug 2017 female Mitchell, Scotts Bluff Co (Brogie, in press)

13-16 Sep 2013 immature photographed Shelton, Buffalo Co (Brogie 2014).

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).

CommentsA 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.”
