Scottish Crossbill (Loxia scotica)
Wryneck (Jynx torquilla)
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.

Plumage a mix of rusty, creamy brown and grey, resembling a nightjar. A rather unmistakable bird, despite the lack of striking plumage features. Behaviour both passerine- and woodpecker-like, but with less woodpecker-like tree clinging. Often feeds on the ground. May give a reptile-like impression.
Sound:Normally silent when not breeding. Song (both sexes): an insisting, Merlin- or Lesser Spotted Woodpecker-like series of plaintive "kee kee kee kee kee ". First slightly ascending, then descending. Other sounds: a guttural "gru", and hissing sounds when threatened.
