THE PEWIT GULL. 
\29 
It is very amusing to see tins Gull run about on land, 
whetlier in pursuit of food or under other circumstances, its 
movements being so very light and graceful, and its general 
appearance so very beautiful, in consequence of its delicate 
plumage, and slender beak and legs. 
Having kept several living specimens of this gull for some 
years, we are enabled to speak with certainty as to the 
changes of plumage it passes through at the different seasons 
of the year. We represent the adult bird in summer plu¬ 
mage, and the immature bird in early spring, and describe 
also the winter plumage of the adult. 
The entire length of the Pewit Gull is about sixteen 
inches ; its beak one inch three lines from the forehead to 
the tip ; the wing, from the carpus to the tip, eleven inches 
six lines. 
The adult bird in summer has the head dark brown as 
far as the nape, including the ear-coverts, chin, and throat : 
the eye is surrounded almost entirely with a white circle, 
except the frontal part which is the same as the colour of 
the head; the eye is dusky ; the eyelid, beak, legs, and 
feet are bright crimson red ; the nape, neck, and all the 
under parts pure white; the back, scapulars, and wing- 
coverts are bluish ash colour; the quills are white with 
black tips, and the outer edge of the outer quill feather 
black. In living birds the white under parts are tinged 
with rose red. 
The winter plumage differs from the foregoing in having 
the head white, as well as all the under parts ; before the 
eye is a crescent-shaped patch of black and grey, and a 
larger semicircular patch of the same colour on the ear- 
coverts ; the back is similar to the summer plumage ; the 
beak, legs and feet not quite so deeply coloured. 
The immature bird has the head, neck, and under parts
