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:

Slightly more compact than Yellowhammer, with shorter wings and heavier bill. In all plumages note; olive to grey rump, greyish lesser coverts and finely streaked flanks. Male unmistakable with black throat and eye-stripe. Female and immature lacks black throat, but have more contrasting eye- and moustache-stripe than Yellowhammer.

Sound:

Song variable, but can generally be described as a Yellowhammer phrase with no ending, or an Arctic Warbler with bunting timbre. Tempo also variable, but rhythm always even. Alarm call a thin "tseeep", similar to Rock Bunting, but more drawn out.
