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:

In all plumages told from Great Grey Shrike L. excubitor by very long primary projection, stout bill, large rectangular wing patch and extended white at base of tail. Tertials without white edge. Adult birds with black forehead (more extended in male and often speckled grey in female), and a pink wash to underparts (especially male). Immatures lack the black forehead and wing coverts have pale fringes.

Sound:

Contact call a series of Magpie-like "che-che-che". Two very different types of territorial song: Most diagnostic is the short song which consists of a single, parakeet-like "irtscha". Like in a sneeze, with rapidly rising and falling pitch. Given monosyllabic, disyllabic or in series. Other song type very varied with lots of mimicry of other birds and mammals. Similar to Woodchat Shrike but usually also includes the call from the short song. The varied song is more subdued in mated males.
