The occurrence and distribution of the Ruby-throated (Archilochus colubris), Calliope (Selasphorus calliope), and Rufous hummingbirds (S. rufus) in British Columbia and Alberta north of the 55th parallel and east of the Rocky Mountains are poorly known. In 2011, we banded Ruby-throated Hummingbirds as far north as North Star, Alberta (56° 52′ N), and as far west as Charlie Lake, British Columbia (121° 00′ W). In both 2011 and 2014, we also banded Calliope Hummingbirds as far north as Charlie Lake, documenting overlap of the ranges of the Ruby-throated and Calliope hummingbirds in northeastern British Columbia in 2011. We confirmed breeding of the Calliope but not of the Ruby-throated or Rufous hummingbirds.
