Falco communis, Gm.; Sharpe, Cat. B. Brit. Mus. i. 
p. 376. 
No. 19. An immature bird. 
Falco concolor, Tem'm.; Sharpe, t. c. p. 405. 
No. 12. Quite a young bird, the determination of which 
has given me some trouble. The peculiar pink hue of the 
under surface is quite different from that of any young 
Hobby with which I am acquainted, and no specimen out of 
our large series of Falco subbuteo can be found to match it. 
I therefore believe it to be an immature Falco concolor s 
although it does not resemble exactly any specimen I have 
yet seen, nor any figure of the young bird. This, I fancy, 
may be due to the fact that the Muscat specimen is younger 
than any previously procured by naturalists. I have asked 
Colonel Miles to endeavour to obtain an adult bird of this 
Falcon, and shall await its arrival with interest. 
The only specimen of this species from North-eastern 
Africa in the Museum is an adult bird from Efat in Shoa, 
obtained by Sir W. C. Harris. It is very much lighter grey 
than any of the Madagascar specimens in the collection, but 
much resembles the figure given by Grandidier and Milne- 
Edwards (Hist. Nat. de Madagascar). This species would 
appear to be subject to melanism, as all the Madagascar 
specimens in the Museum are blacker than the Efat bird.
