THE BLACK AND XVHITE GULL. 303 



Descriptions. 



THE BROWN-HEADED GULL 



IS much about the size of the preceding; the 

 bill is red and sharp pointed ; the under mandible 

 bunching out into a small angle, the eyes black, 

 the irides, or circles, red; encompassed with a 

 broad circle of pale, or white feathers; the head 

 and neck brown, the lower part towards the 

 breast more dusky; the covert feathers of the 

 wings and the back are of an ash-colour, the 

 prime feathers black, with their outer edges, or 

 webs white ; the rest of the body white, tinc- 

 tured with a yellowish sort of pale green. The 

 tail is near five inches long, the legs and feet red, 

 and the claws black. 



These birds are common about Gravesend, in 

 the river Thames. 



THE BLACK AND WHITE GULL 



IS by far the largest of all the gull-kind, 

 weighing generally upwards of four pounds, and 

 being twenty-five or twenty-six inches, from the 

 point of the bill to the end of the tail; and from 

 the tip of each wing, when extended, five feet 

 and several inches. The bill appears compressed 

 sideways, being more than three inches long, 

 and hooked towards the end, like the rest of this
