Swift (Apus apus)
Kestrel (Falco tinnunculus)
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).

CCMedium sized falcon with long tail and long wings. Upperparts brick-red, underparts pale buff with dark speckles. Male; light grey head and tail. Female; brick-red head and tail. Both sexes with broad, black terminal tail-band visible on both sides. Evident, but diffuse moustache-stripe. Hovers more frequently than other raptors. Tail and wings gives a more rounded impression when soaring. Very similar to Lesser Kestrel.
Sound:Most common call a fast series of short, high-pitched "ke-ke-ke". Much less raucous than Merlin or Peregrine.
