62 Col. E. Meinertzlmgen on Birch from [Ibis, 



Juvenile plumage (October) . In this plumage rupicokeformis 

 is even moi-e distinct, the markings on the head, back, and 

 under parts being much heavier and blacker than in any 

 example of F. t. tinnunculus. 



•I am unable to scpai'ate the following individual males 

 from riipicolceformis : — 



Crete (June) : -wing 241. . Senaar (Nov.) : wing 230. 



Sardinia (Nov.) : wing damaged. Sokotra (Dec.) : wing 225. 

 Syria (Oct.) : wing 228. Morocco (Dec.) : wing 239. 



Lower Jordan (Feb.) : wing 237. Morocco (May) : wing 246. 

 Solium, VV. Egypt (Jan.) : wing 236. 



But in examining females from these localities it is clear 

 that these males are only intensely coloured individuals of 

 the typical race ; they are certainly not rvpicolcvformis. 

 One female from Morocco is^ however, inseparable from 

 rnpicokeformis. 



I must also refer birds from northern Somaliland and 

 southern Arabia, resident in both localities, to VKpicola:- 

 formis. Eight males have wings from 220-244, and eleven 

 females from 235-259. 



Birds from Sardinia are puzzling. Both dark males and 

 females are common, but the majority are inseparable from 

 continental specimens in both colour and size. Of two 

 breeding males from (,^rete, one is the pale northern Euro- 

 pean bird, the other a richly-coloured specimen closely 

 resembling Egyptian breeding birds. 



Range. Resident in the Egyptian Delta south to Nubia, 

 southern Arabia, and northern Somaliland. Occurs in winter 

 in the Sudan, where it is possibly resident. 



Milvus migrans (Bodd.). 



The following characters have been noted among the races 

 M. m. migrans, cegyptius, and parasitus, and may be of use in 

 determining visitors to tropical Africa, where all three occur 

 in winter. 



M. m. migrans (Bodd.). Bill black in both adults and young. 

 Breast-feathers with broad daik brown shaft-stripes.
