Status: Rare casual spring migrant west. Rare regular fall migrant west, rare casual central and east.
Documentation: Specimen: display mount at Wildcat Hills Nature Center, Scotts Bluff Co, 23 Jun 1994 Sioux Co (Gubanyi 1996; Silcock and Rosche 1994).
Taxonomy: No subspecies are recognized.
Calliope Hummingbird was formerly included in genus Stellula, which has been merged with Selasphorus (Chesser et al 2012).
Changes Since 2000: There has been a notable increase in numbers detected in fall, especially eastward, where the nine records are all since 2002, eight since 2012. It is not known whether the increase represents an actual rise in numbers or improved identification and detection by observers or a combination of both.
Spring: There are four records, all adequately documented, including one as far east as Knox Co. These are 8 Apr 1962, a female found dead 40 kilometers (25 miles) northwest of North Platte, Lincoln Co, that was identified by Emmet R. Blake at the Field Museum of Natural History (Shickley 1965), but now lost (Bray et al 1986), 18 May 2015, adult female photographed at Creighton, Knox Co (Silcock 2015), 25 May 2015, apparent immature male photographed in southeast Dawes Co (Silcock 2015), and ca. 23 Jun 1994, male captured by a dog in central Sioux Co (specimen cited above).
