Rev. A. C. Smith on the Birds of Portugal. 435 



5. fAQUiLA HELiACA, Sav. Imperial Eagle. " Aguia im- 

 perial." 



I entertain considerable doubts whether the only specimen of 

 this bird in the Museum of Lisbon is a genuine Imperial Eagle, 

 inasmuch as there is not a single trace of white on the scapulary 

 feathers; and though Professor du Bocage, whose attention I 

 called to the fact, accounted for it by declaring the bird in ques- 

 tion to be immature, I cannot find that this distinctive charac- 

 teristic of the species is ever wholly absent, though doubtless it is 

 more conspicuous in adult birds*. There can, however, be no 

 question that the bird is as well known in Portugal as it is 

 in Spain ; indeed it is said to be common in the province of 

 Alemtejo. 



6. t^QUiLA BONELLii (Temm.). Bonelli's Eagle. 



In addition to those in the Lisbon Museum, there are speci- 

 mens of this species in the museum at Coimbra, where it is said 

 to be especially abundant. 



7. t^QUiLA PENNATA (Gmel.). Bootcd Eagle. 



This species is said to be common generally throughout Por- 

 tugal ; and that it is so seems probable from its abundance (as 

 Lord Lilford points out) in Spain. 



The three last-mentioned species appear to be thoroughly at 

 home throughout the peninsula, whereas it seems doubtful whe- 

 ther the hettev -known A. navia and Haliaetus albicilla, though 

 included in Prof, du Bocage's list as probable visitors, have ever 

 been seen within the limits of Portugal. Circaetus gallicus 

 (Gmel.), the Short-toed Eagle, is confidently asserted to be occa- 

 cioually met with ; but it has not as yet been procured for the 

 Lisbon Museum. I think myself bound to add that Prof, du 

 Bocage entertains considerable doubts as to the reported abun- 

 dance in Portugal of A. heliaca, which he assures me he has 

 never seen alive, or, indeed, in the flesh. 



8. tP-A^NDiON HALi.EETUs (Linn.). Osprey. " Aguia pes- 



.eira." 

 Common in localities suited to its habits.
