Our research on Anna's hummingbirds in Idaho was published in September 2016 in the scientific journal Western Birds. The publication documents Fred Bassett's very important capture of a pregnant Anna's hummingbird in Council, Idaho in 2015 and this bird's recapture in 2016. An Anna's x Calliope Hybrid was also caught at the same location in 2016! Bassett's records are the first documentation of Anna's breeding in the state! The article also chronicles the range expansion of Anna's Hummingbirds into Idaho.
