Our observations of Boreal Owls (Aegolius funereus) from 1980-1982 indicate that a resident population is established in the mountains of central Idaho. In late February, 1980, while censusing owls by playback of tape-recorded calls, we located at least four calling males within a 2,100-ha study area near Chamberlain Basin Ranger Station, River of No Return Wilderness. Each owl was heard during at least two censuses between 26 February and 9 March and three Boreal Owls were heard again on 1 April when the study area was recensused. In addition to Boreal Owls, we also found Flammulated (Otus flammeolus), Northern Pygmy (Glaucidium gnoma), Saw-whet (A. acadicus), and Great Horned (Bubo virginianus) owls in the Chamberlain Basin area.
