Appearance:

Only in the UK. Similar to Red and Parrot Crossbill in plumage. Bill size possibly the only visual identification clue, but even this overlaps with the other two species. Bill is usually deeper and heavier than Red Crossbill. Certain separation from Parrot Crossbill in the field by visual characters alone, probably not possible. Species status mainly upheld by isolated breeding population and differences in excitement calls from other crossbills. Calls probably play an important role in maintaining the reproduction barrier between Crossbill populations with different bill-size. See Birdlife link below for more info.

Sound:

Calls very similar to Parrot Crossbill, and sonogram analysis may be needed for certain identification. Flight and excitement calls show most unique quality. Sonogram image above by Ron Summers (used with permission). A detailed article about crossbill calls can be found here.

Appearance:

Small and neat finch with red forehead patch, black bib and base of bill, yellow bill with dark tip and buff wing-bars. Male with pinkish or red chest. Rump streaked, and under tail-coverts with dark centre (as opposed to Arctic Redpoll). Base colour of plumage varies between different subspecies from warm brown to greyish. S.sp. cabaret (often treated as an own species: Lesser Redpoll) has brownish plumage tones, and is smaller than flammea (Common Redpoll). Juveniles lacks red forehead, has less contrasting head markings and more prominent streaking than adults. Underparts with darker streaking, and lores and chin darker than juvenile Linnet and Twite. Dancing flight, with deeper undulations than Linnet.

Sound:

Contact call diagnostic. A chattering "Chutt-utt-utt", with a more metallic and nasal timbre than Linnet and Twite. Other sound includes plaintive call mostly given when perched. Uttered as a continuous sound, but with a disyllabic feel. First part ascending slowly, then faster before it is cut off "tsooeet". Song an improvised chattering on various contact calls with no apparent phrasing.
