The specimen now before us of this species of falcon, is a female ; 
its weight twenty-eight ounces and a half ; length twenty-three inches 
and a half ; bill black ; cere and irides yellow. The whole plumage 
is of a chocolate brown, tinged more or less with ferruginous ; the 
crown of the head is of a dull yellow; legs long and yellow; claws 
black. The male is somewhat less, weighing about twenty-one ounces ; 
length twenty-one inches ; plumage the same, but generally brighter 
in colour. 
These birds are subject to some variety in markings : sometimes the 
crown of the head is white ; others have the whole head white, or 
yellowish ; the shoulders are said to be sometimes yellow; and we 
have seen a specimen with the head, part of the wing coverts, and the 
four first quill-feathers, white. These markings are considered as mere 
varieties, as some are said to be found wholly of a chocolate-brown : 
such, however, are by no means so common as those with a yellow 
crown, or of various shades of that colour to white. In more than 
twenty specimens we have examined, this was the constant mark, 
except as above described. 
This species appears to be local, mostly frequenting swampy moors 
and barren situations ; and though rarely met with in the more culti- 
vated parts, it is the most common of the falcon tribe about the 
sandy flats on the coast of Caermarthenshire, where they prey upon
