Red-footed Falcon (Falco vespertinus)
House Sparrow (Passer domesticus)
Small falcon recalling both Kestrel and Hobby at a distance, but most likely to be confused with latter. Adult male unmistakable with ashy grey plumage and rufous red "trousers". Colour of trousers not always obvious, but silvery upperwing often visible in flashes at distance. Adult female also distinct with almost unstreaked buff underparts and under wing-coverts, buff neck and crown, dark mask and white cheeks. Immature most likely to be confused with Hobby but differs in barred upper side of tail, pale forehead, white (half)collar, contrasting dark trailing edge to wing and more striking fringes to coverts. Underparts also less heavy streaked. Flight profile similar to Hobby but tail slightly longer and more rounded. Hunts insects in flight, but in contrast to Hobby, hovers frequently and with deeper wingbeats than Kestrel.
Sound:Flight call very similar to Hobby, a wryneck-like series of "kew kew kew kew", each call falling rapidly in pitch. Sometimes given in a harsher more staccato version. Very vocal at colony with various squeaky and whimpering begging calls.

Male told from Tree Sparrow by grey crown, grey cheeks with no cheek-patch, larger black bib and grey rump. Female rather featureless, and thus not likely to be confused with Tree Sparrow. Confusion with female Scarlet Rosefinch possible, but underparts unstreaked. Profile of House Sparrow differs from Tree Sparrow by larger, less rounded head and less heavy bill.
Sound:Most calls very similar to Tree Sparrow, but lacks said species' distinct high pitched call (chew-itt), and alarm call is less dry and raucous. Song a primitive, monosyllabic, or slightly disyllabic "chilp", hard to distinguish from Tree Sparrow.
