feathered-legged Eagles, but merely on the front and 
sides. 
_ The various species forming this genus are found 
in Europe, Asia, and North America. The European 
Rough-legged Buzzard (Archibuteo dagopus) has been 
known, though very rarely, to breed in Great Britain, 
and is not an unfrequent autumnal visitor to our 
coasts, where in some years it has appeared in con- 
siderable numbers, especially in the Eastern Counties. 
These migratory arrivals are almost entirely composed 
of birds of the year, which have probably traversed 
the German Ocean after leaving their native haunts 
in the north of Norway and Sweden, where they 
in great measure subsist on that singular little rodent, 
the Lemming, the strange migrations of which are 
believed considerably to influence the movements of 
this and other Scandinavian birds of prey. 
Of the genus Luteo, one species, Butco vulgaris, is 
a native of England, where it is called the Common 
Buzzard, because, though now comparatively rare, it was 
before the trap and the gun had reduced its numbers, 
one of the commonest of the British Birds of prey. 
This species is found throughout most parts of Europe 
and Western Asia; its chief food appears to consist 
of mice, moles, and lizards. The Norwich Museum 
contains a fine series of various species of the genus 
Buteo, as well as of the two succeeding genera, 
Tachytriorchis and Leucopternis, both of which are 
limited to the Continent of America.
