EAST AFRICAN BIRDS. 915 



BUTEO AUGUR Riipp. 



A male Augur Buzzard sliot on a rock had a large black rat 

 (A. ieneb)'0S7is ?) in its stomach (Mtali's, 19. x. 21). Another male 

 shot in a tree had an Unstriped Grass-Rat (A. a. neumanni) iii 

 its stomach aiid in its crop a lizai-d [Eremias sjjekii) (Ndala, 

 15.xi. 21). 



Two newly-fledged young were shown me by a native child 

 who was about to eat tliem. I saw a nest in a thorn-tree among 

 the rocks, but it was empty. The natives say that the buzzards 

 nest here every year (Mtali's, 19.x. 21). A nest was seen in a 

 tree leaning out over the edge of a rocky krantz. My collector 

 shot the hen bird and took the eggs, which were quite fresh and 

 measured 52 X 62 mm. They were \^hite with brown smudges 

 and reticulations, mostly at the lower pole, but also extending 

 towards the upper pole (Shanwa, 23. x. 22). 



Mbi-ierax canorus jietabates Heugl. 



An immature male Northern Chanting Hawk with two lizards 

 (B. spekii) in stomach (Ulugu, 7.xi.21). An adult male with a 

 pregnant lizard (Ayama atricollis ?), grasshoppeis, and many 

 parasitic nematodes, which were not preserved, in its stomach 

 (Ndala, 15. xi. 21). 



Melierax poliopterus Cab. 



A nest containing a single nearly-fledged young of the White- 

 rumped Chanting Hawk was built in a tree growing from a 

 fissure in the rocks. Its plumage was striking)}' different from 

 the adult. The back plumage is nearlj'^ black; it has a central 

 gular streak, but the lower breast shows signs of barring like 

 the adult. When first seen it was being fed on an agama 

 lizard by its parent, but it soon took to feeding itself on scraps of 

 meat cut up small (Shanwa, 24.x. 22). The stomach of another 

 specimen shot at Mwadira contained an agama and grasshoppers 

 .(19.x. 22). 



Circa iixus fasciolatus Gray. 



The Banded Harrier-Eagle is, I believe, a somewhat scarce 

 bird ; in the stomach of a male shot to-day there were remains of 

 a rat {R. c. m/icrodon) and the scales of a lizard, apparently those 

 of Mab'uia striata (Mkindo River, 8. ix. 21). : 



Circaetus cinereus Vieill. ; 



A female Brown Harriei'-Eagle had snake scales in its stomach 

 (Mtali's, 19.x. 21). 



Kaupifalco monogrammica Temm. 



The stomach contents of a One-streaked Hawk, shot at 7 a.m., 

 were a gerbil (^Taterona vicina ?) and a freshwater purplish crab,
