Tue Rock Prerr in its habits, mode of flight, and song, so 
closely resembles the two species already described, as for 
a long period to have been confounded with them. Colonel 
Montagu became aware of the distinction, and suggested 
the subject to Mr. Lewin, who figured and described 
this species under the name of Dusky Lark, in his large 
work on British Birds, with coloured illustrations.
