BIRDS OF ETHIOPIA AND KENYA COLONY 63 



Other variable factors are the number of bars on the outer and 

 the inner webs of the outermost primary. On the outer web the 

 number varies from one (the terminal dark bar) to five; on the inner 

 web from three to five. 



The wing measurements given by Swann ^^ are too small. Ac- 

 cording to him, the wings of male birds measure from 385-390, and 

 of females 396 millimeters, while the series before me gives the fol- 

 lowing limits: 365-397 millimeters in the male and 393-400 in the 

 female. 



One of the birds collected at Gato River had an entire rat, appar- 

 ently recently eaten as it had the skin and hair on it, in its stomach. 



The crested hawk eagle occurs throughout Africa south of the 

 Sahara, and in all this enormous range has not become differentiated 

 into geographic races. The Frick expedition observed it at the fol- 

 lowing places: Aletta, March 7-13, 12 birds; Loco, Gidabo River, 

 March 13-15, 2 seen; Abaya Lakes, March 18-26, 5 individuals; 

 Gato River, March 29 to May 17, 54 seen ; Boclessa and Sagon River, 

 Ma}^ 18 to June 6, 10 birds ; Meru and Kilindini, August 10, 2 seen ; 

 Tana and Thika Rivers, August 23-27, 8 birds; west of Ithanga 

 Hills, August 28, 4 seen ; Athi River, August 29-30, 10 ; Escarpment, 

 September 4-12, 4 birds seen. 



Mearns noted that this eagle may be partly nocturnal as it fre- 

 quently cries at night as well as during the day. 



TERATHOPIUS ECAUDATUS (Daudin) 



Falco ecaudatiis Daudin, Traite, vol. 2, p. 54, 1800: Pays d'Anteniquoi ; i. e., 

 Knysna district. Cape Province. 



Specimens collected: 



Male, Sagon River, Ethiopia, June 4, 1912. 



The bateleur is widely distributed thoughout Africa from the Cape 

 Province north to the southern limits of the Sahara from Senegal 

 to the Anglo-Egyptian Sudan, Ethiopia, and Eritrea, and, while 

 variable in the sense of having color phases, is not divisible into 

 geographic races. 



The single specimen collected is rather small, having a wing length 

 of 510 millimeters. Swann ^- records the wing length of the male as 

 532 millimeters. The present specimen has grayish shoulders, but 

 has black greater upper wing coverts. The figure in Von Heuglin's 

 " Ornith. Nordost-Afrikas," ^'' of his variety fasclatus has the greater 

 wing coverts brown.
