PALCONIDJi; TINNUNCULUS 285 



esting range; it spends the northern summer' in Amoorland, Japan, 

 and North China, where it nests; Leaving the neighbourhood of 

 Pekin in September, ■ it passes through ' India, where it has been 

 regularly observed in Cachar in October and November. It spends 

 our southern summer, from October to March, in South Africa, 

 where it is foufld in the upper part of Natal, the Transvaal, and 

 Ehodesia. Hitherto curiously enough it does not seem to have 

 been met with in east Africa. 



The following are recorded localities : Cape Colony — Knysna 

 (Andersson), King Williams Town (S. A: Mus.); Natal — Near Maritz- 

 burg, common in summer (Ay res) ; Transvaal — Potchefstroom, 

 December, January (Ayres) ; Bechuanaland — Boatlanami, December 

 (Ayres) ; Rhodesia — between Bulawayo and Victoria Falls, De- 

 cember (Oates), near Salisbury (Marshall) ; German south-vrest 

 Africa — Rare in Damaraland (Andersson) ; Portuguese east Africa — ^! 

 Zambesi valley (Kirk) . 



Habits. — Like its western relative the Eastern Red-legged 

 Falcon is a gregarious bird, hunting in companies of twenty to; 

 several hundred, and scouring the ground for insects which form", 

 its food exclusively. Marshall found ■ in the stomach of one! 

 examined, eighteen Pentatomid bugs, six water beetles, one grass-; 

 hopper, two winged Carabara ants, and a number of winged termites. 

 They are fond of the neighbourhood of streams and are usually 

 seen in the evening. 



Mr. Seebohm observed a flock of perhaps 300 of these Falcons in 

 the early part of March on a farm in the upper part of Natal. 

 They spent the day hawking like Swallows at a great height in the 

 air, and at night roosted all together on the naked branches of some 

 tall trees in the bush. 



It is not probable that either this or the previous species will be 

 found breeding in South Africa.
