Currently, the Anna’s Hummingbird (Calypte anna) breeds along the west coast of North America from Baja California to British Columbia and east into inland areas of California, Arizona, New Mexico, Oregon, and Washington (Clark and Russell 2012). The current distribution is a result of 80 years of range expansion out of Baja and coastal California, largely facilitated by urbanization, landscaping with non-native plants, and supplementary feeding (Greig et al. 2017, Battey 2019). Pollock et al. (2021), summarizing the recent increase in the numbers wintering in Idaho, illustrated that the species’ range continues to expand. This increase in winter numbers over time mirrors the trend in Arizona in the 1960s, when the establishment of a breeding population followed wintering (Zimmerman 1973, Clark and Russell 2012). Pollock et al. (2021) further suggest that Anna’s Hummingbird may now be a sparse year-round resident in parts of Idaho, primarily the greater Boise metropolitan area. Given the recent trend in Idaho that includes an increase in summer numbers in the past three years (ibid.), the establishment of a breeding population in the state seems possible, even probable.
