46 ELEONORA FALCON. 



one with the other. The only similarity between the 

 two birds is that they are each unicolorous; but then 

 the colour of one is chesnut; the other dark slate or 

 lead-colour; while there are specific points of difference 

 between them sufficiently clear. I have, however, amid 

 the uncertainty which exists, thought it better to omit

The Eleonora Falcon is found in Sardinia, Greece, 

 and Syria; and it occurs also in Africa. It seems to 

 prefer plantations and shrubby woods for its residence. 

 According to Prince Bonaparte it nests in July and

Nothing more seems to be known at present of its

 the under parts are fringed with a reddish tint, more

 inches long, and the same colour as the rest of the 

 body, but barred underneath Avith nine or ten rows of 

 darker tints. Cere, tarsi, and feet are said to be 

 greenish yellow; claws black. 



The female, which is labeled by M. Verreaux as in 

 immature plumage, is so exactly like the Hobby, that
