coverts, the innermost secondaries conspicuously paler, whitish

Adult Female, — Similar to the male, but slightly smaller. 



Young, — Similar to the adults, but with less white on the 

 forehead, and to be distinguished by some brownish spots on 

 the under tail-coverts. 



Range in Great Britain. — A rare and occasional visitor, having 

 only been met with on two occasions, both in the middle of 

 summer. One was shot at Great Horkesley, near Colchester, 

 on the 8th of July, 1846, and another towards the end of July, 

 1879, near Ringwood in Hampshire. In the latter case, two 

 were observed flying for some days over the River Avon. The 

 species has not been obtained anywhere else in Europe, and 

 the Needle-tailed Swift is apparently one of those birds which, 

 for some reason or other, sometimes w'anders w^estward, out of 

 the ordinary course of its migrations. 



Range outside the Biitisli Islands. — The breeding range of this 

 siiecies extends from the neighbourhood of Krasnoyarsk in 

 Siberia eastwards to Amoorland and South-eastein Mongolia, 

 as well the northern islands of Japan. In winter it migrates 

 by way of China to Australia. 



HaMts. — Very similar to those of our Common Swift. It 

 arrives in its northern quarters about the end of April or the 

 beginning of May, and departs in August, a few staying on till 

 September. On migration vast flocks are often seen. Its 

 powers of flight are prodigious, and it is often noticed at a 

 great height in the air. It also visits the lowlands in the 

 vicinity of the mountain f ;slnesses in which it breeds, and is 

 there noticed hawking over the ground in company with other 

 Swifts.
