244 Capt. J. H. Speke on Birds collected 



again during my recent expedition into Eastern Africaj as far 

 south as 6° S. lat. They fly about in large flocks like the 

 common Parroquets of India^ and make a loud and continuous 

 chatter. Their irides are red. 



3. Helotarsus ECAUDATUS (Daudin). Native name, iVaSorfi. 



I have seen this bird also as far south as 6° S. lat. Irides 

 red. It is said by the natives to be very destructive to small 

 animals, and to lay only one egg. The specimen obtained had 

 a nest of small sticks loosely placed together in the upper 

 branches of a large Mimosa-tree. It was very shy and hard 

 to kill. 



3. Melierax polyzonus (Riippell). Native name, Hat- 

 kaadag. 



Irides red. It flies very swiftly ; with the habit of a Sparrow- 

 hawk. Shot on the Plateau. 



4. Bubo africanus (Temminck). Native name, Shimir- 

 libah, meaning "the Lion-bird." 



5. BucEROs flavirostris, Riippell. Common Somali Horn- 

 bill ; called there Kudunkutu. 



These birds fly about in bodies of five or six together, make a 

 loud croaking sound, not unlike a frog, and are especially noisy 

 about sunrise. These also I found six or seven degrees south 

 of the equator during my recent journey. 



6. Irrisor senegalensis (Vieillot). 



These birds are also numerous in more southern latitudes. 

 They fly in flocks of fifteen to twenty, and feed in Acacia-trees. 

 They have a very ofifensive odour. 



7. Irrisor minor, Riippell. 



The female is much smaller than its mate, and has a still 

 more arched bill. Living on the Plateau, they usually frequent 

 thickly-leaved large Acacia-trees to feed, and make a peculiar, 

 loud, unmusical noise, but have not the same unpleasant voice as 

 the Irrisor senegalensis. 



8. Denduobates 7ETHI0PICUS (Ehrenberg). 



Called by the natives Daudaute, from the sound it makes
