Taxonomy: No subspecies are recognized (AviList 2025).
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.” Along the same lines, in reference to a male Black-chinned apparently paired “for several weeks” with a Ruby-throated in North Platte, Lincoln Co, Nebraska in Jun 2022, Sheri Williamson commented ““Sad to say that Black-chinneds are on the decline here in southeastern Arizona, but at least they seem to be taking advantage of new opportunities further north. It’ll be interesting to see if a new hybrid zone develops as Black-chinneds expand into areas with Ruby-throated populations.”
A possible Nebraska hybrid is discussed in Comments. A male Black-chinned Hummingbird was paired with a Ruby-throated Hummingbird 16-23 Jun 2022 at North Platte, Lincoln Co; the latter had been present “a few weeks”.
Summer: May 22, 24, 26 <<<>>>Aug 29, 29, 30
Earlier dates are 7-8 May 2012 photographed Scottsbluff, Scotts Bluff Co photo (DeLara and Smith 2013, Brogie 2013), 11 May 2022 male Ogallala, Keith Co (Ochsner, eBird.org), 13 May 2019 male photographed at Croft feeders, Scotts Bluff Co (eBird.org), and 19 May 2025 Turkey Drive, Scotts Bluff Co.
Later dates are 8-10 Sep 2022 at a Kearney Co feeder (Robin Harding, personal communication), 13-16 Sep 2013 immature photographed Shelton, Buffalo Co (Brogie 2014), and 18 Sep-2 Oct 2018 at the Smith feeders, Scotts Bluff Co (eBird.org).
There are about 60 documented records, almost all from 2019-2025, indicating the steady increase in records since the first in 2012.
The first indication of possible breeding was the appearance of an immature at the Croft feeders in Scotts Bluff Co 13 Jul 2023 (Steven Mlodinow, personal communication). In 2024, a male and a female were at the Croft feeders 24 Jun-11 Jul, although no breeding evidence was noted. Evidence was stronger in 2025, when two apparent pairs were reported in Scotts Bluff Co. A female arrived on Old Stage Road 19 May; possibly the same female was at Turkey Drive feeders 20 May, soon joined on 21 May by a male, with both continuing through at least 1 Aug, when breeding was confirmed by the presence at the feeders of a pair with two juveniles. At Wildcat Hills NC, a female arrived 24 May, joined by a male 29 May, a male continuing almost daily through 30 Jul, with two males seen only once, on 13 Jun. Sightings of a female were intermittent, with only six reports 24 May-26 Jun, none in Jul. The only evidence for breeding at WHNC was a male in courtship display to a female 26 Jun 2025.
Nebraska is east of the summer range and so sightings in the state would be expected to reflect spring migrants lead by males in May, summer vagrants, and fall migrants. The latter generally follow a pattern of adult males first, as early as late Jun, followed by adult females and young birds Jul-Aug (Baltosser and Russell 2020).
Records from the east and central are 11 May 2022 male Ogallala, Keith Co (Ochsner, eBird.org), 29 Jun 2014, male photographed at a Lake McConaughy, Keith Co feeder 29 Jun 2014 (Brogie 2015), 30 Jun-17 Aug 2021 female/immature Lincoln, Lancaster Co (Michael Willison, eBird.org), 8 Jul 2017 and about a month prior, photographed Blair, Washington Co (Brogie 2018), 13-16 Sep 2013 immature photographed Shelton, Buffalo Co (Brogie 2014), and 16-23 Jun 2022 male paired with Ruby-throated Hummingbird present “a few weeks” North Platte, Lincoln Co.
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. 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). Two “young birds” in a well-known hummingbird yard in Scotts Bluff Co 12 Aug 2016 were thought to be this species but were not photographed (eBird.org). 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. An immature photographed at the Croft feeders, Scotts Bluff Co 19 Sep 2018 was judged to be a Ruby-throated Hummingbird (eBird.org; Brogie 2019), while earlier at the same feeders, an immature Black-chinned Hummingbird was present at least 25-29 Aug (eBird.org); one or both of these immatures were present during 25 Aug-21 Sep (Colin Croft, eBird.org).
A puzzling bird with a strongly decurved bill in Lincoln, Lancaster Co 30 Jun-17 Aug (fide Michael Willison) was determined to be this species by Sheri Williamson albeit having a bill that was “on the decurved end of the bell curve”.
Comments: Bray et al (1986) discussed a specimen in the B. J. Olson collection at Kearney State College purportedly collected in Buffalo Co Aug 1903 by C. A. Black, but later determined by Swenk (1920) to have been purchased from an Arizona collector; Swenk (1920) removed the species from the state list. Swenk’s (1919) note that there was one Nebraska record of Black-chinned Hummingbird presumably refers to this 1903 specimen.
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, personal communication). 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 abundance of Black-chinned Hummingbird in western Kansas in 2015 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.” Joseph Grzybowski (personal communication) noted in 2019 for Oklahoma “In 1993, there was a surge of Black-chinned Hummingbirds into the Wichita Mountains at least” and “In recent decades Black-chinned Hummingbirds began to expand into central Oklahoma such that one can no longer assume a hummingbird in, say, Oklahoma City or Cleveland County is a Ruby-throated.” Ted Floyd noted in Jul 2024 that Black-chinned Hummingbird “continues its inexorable march across western Weld Co” Colorado (post to COBIRDS 7 Jul 2024).
