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:

All plumages differs from Reed Bunting, and most other buntings by; white belly, pale cheek-patch, flanks coarsely spotted in rufous red, rufous rump with no streaking, pale pinkish legs and lower mandible. Summer plumage male easily recognized by boldly rufous breast and contrasting black and white head pattern. Young male resembles females, and may breed before adult plumage is fully developed. Posture often erect when moving around on the ground. Crown feathers often erect. Flight pattern light and fluttering, and more even than in Reed Bunting.

Sound:

Contact call a short "zick", like Little Bunting, but slightly sharper. Song distinct and melodic: A soft, fluting phrase in an undulating rhythm. Integrated in the flute-like tones are high-pitched, dunnock-like bi-notes, especially towards the end of each phrase.
