Mandarin Duck (Aix galericulata)
Swift (Apus apus)
Male unmistakable with its stunning colours. Broad, white eyestripe from bill to nape, and two conspicuous wing sails. Large head, compact body and long tail. Female and juvenile also distinct, but may easily be confused with Wood Duck. Differs from this by "clear cut" base of bill without wedges, less white around eye, paler head and coarser white markings on flanks. Juveniles similar to female, but browner and duller. Often perches on branches and logs.
Sound:Display call a thin, whistling and rapidly rising "hueessst, accompanied by deeper clappering sounds. Other sounds include a short and sharp, coot-like "ket", and a short "ack".

CCAll black swift with small white throat patch. Very difficult to separate from Pallid swift and Plain Swift. Pallid Swift; brownish plumage tone (best seen against darker background), bigger throat-patch than swift, scale pattern on body more prominent, wing-tips slightly rounded, "saddle" darker than wings, and more contrast between darker outer primaries and inner. Plain Swift; throat patch smaller and more diffuse than swift, wings and body more slender, tail noticeably deeper forked.
Sound:A shrilling trill "zreeeee" of about 1 -2 seconds length, gradually rising in pitch with accentuated firs half, then falling from the middle of phrase. Often continued with a dry lower pitched "trrrrrr" before calling again. Very vocal at breeding area, and often a flock will call together. Despite being quite similar to Pallid Swift, the call is probably the best field character to separate the two. Pallid puts the stress on the ending of the call, followed by a quick fall in pitch (dynamics like moaning with a quick release). Plain Swift calls similar to Common Swift, but differs in slightly fluctuating pitch during the call, and a loss of resonance towards the ending (thinner sounding).
