Détails de l'observation
Unexpected here, although likely annual or semi-annual in eastern Boulder County. Initially heard giving incessant toots from backyard in the downtown, and later in a thick row of spruce several hundred yards away. Unlike the vocalizations of other species except for pygmy-owl, which is predominantly diurnal. No visual, but heard from close distance.
