ROCK PIPIT. 397 



under tail-coverts, yellowish brown, slightly tinged with 

 green, spotted and clouded with brown : the flanks olive 

 brown ; the legs, toes, and claws, brown ; the hind claw 

 longer than the toe, larger than that of the Meadow Pipit, 

 and considerably curved. 



The sexes do not differ in plumage ; during the breeding 

 season the adult birds on the upper surface of the body are of 

 a dull brown ; but slightly tinged with green, and the outer 

 tail-feathers on each side exhibit more white. After the 

 breeding season, old birds and the young birds of the year 

 have more of the olive tint above, and the outside tail-feathers 

 are dull whitish brown. 



The whole length of an adult bird is about six inches and 

 three quarters, but rather less than more. From the carpal 

 joint to the end of the longest primary three inches and five 

 eighths ; the first quill-feather rather the longest of the whole ; 

 the next three but a trifle shorter than each other in succes- 

 sion ; the fifth feather three-eighths of an inch shorter than 

 the fourth.
