Blue Rock Thrush (Monticola solitarius)
Red Crossbill (Loxia curvirostra)
A slim, medium large thrush attached to rocky terrain, mountains or concrete buildings. Differs from Rufous-tailed Rock-Thrust, Monticola saxatilis in all plumages by long bill, and long, dark tail (not rufous). Bill and tail gives the bird an elongated appearance and profile. The tail reaches far behind the primaries when perched. Male unmistakable if seen well, but note that the bluish tones appears dark grey in unfavorable light. First winter males are barred underneath but gradually turns bluer and more evenly coloured. Immatures and females look alike with grey-brown upperparts and barred underparts, and are generally darker in throat and breast than M. saxatilis.
Sound:Alarm call consists of short, soft whistles. Often two notes in sequence, the second one higher ("pjuu-eee"), and sometimes followed by series of dry "check" sounds. The song is a beautiful, melodious fluting which can be very difficult to distinguish from M. saxatilis. It generally has a more melancholic feel, with more tremulous fluting than the latter, with less lingering in the higher register. The structure is variable and simple, but sometimes more elaborate in song-flight or when including mimicry. Both sexes sing, but male most actively.

CCVery similar to Parrot Crossbill, but has thinner neck, smaller head, steeper forehead and slender bill. Upper mandible is less curved towards the tip than in Parrot Crossbill, and the lower is straight, with no bulge. The tip of the lower mandible protrudes from behind the upper (tips of mandibles visibly crossing). The chest is less deep, and birds are not so front heavy. Large individuals may be difficult to identify because of overlapping characters with Parrot Crossbill. Plumage similar to Parrot, with dark wings and tail. Males with rufous red head and body, females green. Juveniles greyish green with streaking. Posture more erect than Parrot Crossbill, especially when foraging on ground.
Sound:Contact call similar to Parroy Crossbill's "tupp", but is on average higher and less powerful, with a "cut-off" ending. In sum: Parrot Crossbill; hard attack, soft ending, Crossbill: softer attack, cut-off ending. Beware regional variations and overlap in pitch of calls with Parrot. The song consist of improvised, resonant twittering, and series of contact calls with no apparent phrases. It is generally faster, with less marked pauses than in Parrot Crossbill, and the phrasing seems more random.
