Jack Snipe (Lymnocryptes minimus)
Swift (Apus apus)
Notably smaller, darker and with shorter bill than Common Snipe. Two prominent yellowish back-stripes. Dark wedge-shaped tail, and slightly rounded wings. Lacks median crown-stripe. Flanks spotted, not barred. Diagnostic behaviour: Usually flushed only at close range. Takes off silently, then quickly lands nearby. Whole body bounces rhythmically when feeding.
Sound:May occasionally give a harsh, nasal and rolling "reearrr" when flushed, but is usually silent. Display call a peculiar, cyclic and rhythmic sound performed in flight. Recalling a galloping horse in the distance. "Galloping" interspersed with cyclic, whistling, hissing sounds. Hard to locate when displaying. Seems both close and distant at the same time.

All 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).
