Blue Rock Thrush (Monticola solitarius)
Common Loon (Gavia immer)
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.
