Status: No accepted records.
Taxonomy: No subspecies are recognized (Pyle 1997).
Comments: The only report accompanied by tangible evidence is that of a specimen HMM 2866, collected by Wallace and Brooking near Meadow in Sarpy Co 19 May 1921 and now on display at the Hastings Municipal Museum (Bray et al 1986).
We have reservations about the provenance of this specimen, given the existence of other unique specimens in the Brooking collection (See Introduction, “The Swenk years, 1900-1940”). Although Black-capped Vireo apparently was “quite common” and bred in south-central Kansas in the 1880s, it has not been acceptably recorded there since, probably because of Brown-headed Cowbird nest parasitism (Thompson et al 2011, Grzybowski 2020). The current nearest breeding population is in southwest Oklahoma, where it persists largely due to control of Brown-headed Cowbirds (Grzybowski 2020). A case could thus be made for a spring overshoot migrant during the 1880s, at about the time of the Omaha report cited above but seems extremely unlikely as late as 1921.
There are two additional published references to the appearance of this species in Nebraska. Skow was said to have recorded it in the Bellevue, Sarpy Co area (Bruner 1896), and Trostler and Skow saw and “thoroughly identified” a single bird near Bellevue 19 Jun 1894 (Bruner et al 1904). These reports appear to be of the same sighting; neither was documented. Indeed, Swenk (Unpublished notes in NOU Archives) stated “Mr. Skow states that his record of the black capped vireo, as previously published, is to be regarded as doubtful.”
