Boreal Owl (Aegolius funereus)
Arctic Redpoll (Acanthis hornemanni)
Small owl with large, square head and spotted upperparts. Eyes bright yellow and facial disks white. "Astonished" expression. Size approximates that of Little Owl, but appears more bulky. Head much larger than in Pygmy Owl, and flight pattern includes interspersed glides without bounding. Seldom seen in the open.
Sound:Song consists of fast series of fairly deep whistling notes "po-po-po-po-po-po-po-po", slightly ascending in pitch, and descending in the last few syllables. Phrase includes up to 25 units. Other calls include a drawn-out, squeaky "kweeat" and some peculiar, explosive sounds with an almost "electronic" quality.

CCDiffers from Common Redpoll by white, almost unstreaked rump (young birds may have some streaks). Under tail coverts white, with only very narrow black center, or no black at all. Upperparts greyer, underparts whiter with less prominent streaking. Wing bars brighter. Bill shorter and less deep, and face "flatter". Juveniles difficult to distinguish from Common Redpoll, even when held in hand. Species status debated.
Sound:Very similar to Common Redpoll, but possibly with a softer tone and slightly longer pauses between each syllable. See Common Redpoll.
