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:

Distinguished in all plumages by double wing-bars and white outer tail feathers. Male easily recognized by slate grey crown and nape, and pinkish face and underparts. Female with greyish green upperparts and whitish underparts. A long-tailed finch with peaked head. Appears more elegant in flight than other finches. Tripping gait when on ground.

Sound:

Song a falling 5 sec. phrase "zitt-zitt-chep-chepp-chu-chu-churrurrwitt". Structurally similar to Willow Warbler, but with a conclusive, ascending and accented ending, and with a much harder, finch-like, timbre.
