LARK. 279 



irides hazel ; the top of the head, and upper parts in general, are 

 rusty olive brown, streaked with dusky ; rump plain ; quills dusky, 

 the primaries slightly edged with olive green ; all the under parts of 

 the body pale ferruginous, darkest on the breast, vent, and under 

 tail coverts ; lightest on the chin ; sides of the neck, breast, and body 

 marked with oblong dusky spots; the two middle tail feathers dusky 

 brown, paler on the margins ; outer feather white, except towards 

 the base of the inner web, and the outer web is brownish towards 

 the point ; the second is white only at the tip ; the rest dusky black, 

 slightly edged with dusky brown ; the legs dull yellow ; claws horn- 

 colour, hind claw rather longer than the toe, and a little bent. 



The Pipit Lark is rarely seen, except in the winter months, and 

 only to be distinguished from the Titlark by the superior size, olive- 

 colour on the upper parts, and being more ferruginous yellow beneath ; 

 though by mixing with the Titlark, at the above season, and being 

 found in the same places, it has generally been confounded with it. 

 Colonel Montagu observes, that he has killed it in Cornwall, in very 

 severe weather in December, and from later experiments, seems to 

 think, the Tit and Pipit Larks to constitute only one species, and the 

 Field Lark to be distinct, and that the two former only differ in the 

 colour of the plumage, according to the season.*
