Bonelli's Eagle

Aquilla fasciata

Very rare visitors to Britain, chiefly in the Spring.

Residents in Europe.

Adults  are dark brown above, from a cold hue similar to dark chocolate to an umber as well as to some extent individual and regional variances, with pale margins to most feathers.

Adult's tail is grey with obscure darker brown thin bars, with a broad blackish subterminal band and creamy white tip. 

Juveniles are a lighter medium brown above with variable paler edges, sometimes with a creamy patch on the back (not the mantle as in the adults) and uppertail coverts.
