76 Dr. Heaglin on some Birds of North-Eastern Africa. 



I cannot decide the question whether B.tachardus from Smyrna 

 and from Southern Russia ought to be referred to the present 

 species, nor do I know whether B. minor is a stationary bird in 

 the Sudan. 



The following are the other known species of the genus in 

 North-Eastern Africa : — 



1, 2. BuTEO ANCEPs and B. eximius, Brehm (' Naumannia/ 

 1854), are known to me only from the names. They are found 

 on the Blue Nile. 



3. BuTEO RUFiPENNis, Suudcv. and Strickl.* has been erro- 

 neously taken by myself for a species of Circus, and described 

 and figured as Falco mulleri, nob. (' Naumannia/ iii. 1849), 

 Sundevall has correctly classed it as a Poliornis, Kaup. It is 

 frequently found in the months from June to November round 

 Chartum, on the Bahr el Abiad, and in Kordofan ; its habits 

 approach to those of Circus pallidus, but it is also frequently 

 found sitting on trees. 



4. BuTEO RUFiNUS, Riipp., is, without doubt, identical with 

 Buteo ferox, Gm., andButa'cfus leucurus, Naumann. I have found 

 this beautiful bird from October to March, generally in pairs, along 

 the Nile, in Upper Egypt and Nubia, and still more frequently 

 in Eastern Sennaai-, and in the forests of the North-Western 

 Kolla. The iris is dark brown ; bill bluish ; base of the mandible 

 lead-grey ; angle of the mouth, cere and feet yellowish. Imma- 

 ture specimens have the ground-colour of the tail light brownish- 

 grey, with ferruginous shades. The wings extend to a distance 

 of 8 inches from the end of the tail. The total length of the 

 male is about 20 inches ; that of the female 22 or 23 inches. 



5. BuTEO AUGUR, Rupp. 



This is a beautiful bird, representing B.jacal of Southern 

 Africa. It is frequently found southwards from Mareb, in 

 Eastern and Central Abyssinia. 



6. BuTEO VULGARIS, Bcchst. 



Occasionally seen during the winter in Egypt. According to 

 Riippell, " Everywhere in N. E. Africa."
