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:

Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Upperparts brown-grey, tail rufous brown. Underparts dull white. Throat with faint streaking on each side. Very similar in appearance to Nightingale, but tail is not as rufous, and contrasts more with the grayer/brownish back. Overall more drab appearance. Thrush-like behaviour despite the small size, with jumping gait, raised tail and drooping wings.

Sound:

Alarm call alternates between a thin, high pitched, "piuu", and a characteristic dry, rattling, frog-like "rrrrr". Song a highly distinct mix of extremely resonant, full-bodied notes and species specific, dry, rolling, rattling sounds. Can only be confused with Nightingale, but lacks this species' interwoven series of slightly ascending, plaintive notes.
