Needle-Tailed Swift

A needle‑tailed swift (Hirundapus caudacutus) is seen slightly from above as it flies over a mountainous landscape. Also known as the white-throated needletail, or spine-tailed swift, the needle-tailed swift is a migratory bird in the family Apodidae. In the summer, it breeds in the mountainous region of Central Asia and is rarely seen in western Europe. It is the fastest bird in flapping flight.
