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:

Slender warbler with long tail, short wings and pointed bill. Restless and alert with frequently raised crown feathers and dark eye framed in red. Male with black head, white throat, greyish upperparts and off-white underparts. Female less striking, with grey head grey-brown upperparts, distinct buff flanks and paler belly. Both sexes with white sides and corners to tail. Rarely sits exposed, and usually betrays itself by it's frequently used scolding call. Often just glimpsed when it dives into a bush, spreading it's tail and showing the white markings.

Sound:

Epitome of mediterranean sylvias, and learning the songs of the genus should start with extensive listening to this species (use xeno-canto link below). Scolding call a machinegun-like, short and harsh rattle. Usually consisting of 2-5 notes with some variation in timbre and delivery. Song a stream of varied, short notes, constantly interspersed with variations of the scolding call. Phrases 2-5 sec. long. Easily confused with several other sylvias, especially in the eastern part of the Mediterranean. Rattling sound (in both song and call) differs from most other congeners by being considerably harder and more "smacking". Dartford Warbler most similar, but usually betrays itself by it's characteristic and frequently used contact call (also interspersed when singing).
