BLACK-HEADED GULL. 
are able to fly, they scatter about the neighbourhood, to feed 
on moist meadows and such places; whence they are shortly 
conducted by their parents to the nearest coast. 
This pretty-looking bird resorts to fenny districts and the 
sides of pools and inland waters and their islands to breed, 
and vast multitudes congregate together for the purpose, as 
well both near the sea as farther from it, and on the lands 
adjoining the sea itself, if low and marshy. 
The nest is flat, and a composition of grass or the tops of 
reeds and sedge, placed, perhaps, on a tuft of rushes or other 
such herbage. 
If the first set of eggs be taken a second is laid, and a 
third if the second, but in such cases they are less each time 
in size. They are valued as food, and in some places are 
farmed for the purpose. 
The eggs, two, three, or sometimes, it is said, four in number, 
are laid the middle or end of April, or beginning of May, 
chiefly at the latter season, and are hatched the end of May 
or early in June. They vary exceedingly in colour and mark¬ 
ings; some are light blue, others yellow, and others green, 
red, or brown. Some have scarcely any spots, and others are 
thickly covered with marks of different shades of brown and 
reddish brown. One beautiful variety has been described, the 
ground-colour a very light greenish white, blotted with two 
shades of rich brown. In some instances they are found 
entirely white. 
The young birds leave the nest and betake themselves to 
the water as soon as hatched. 
Sir William Jardine writes, ‘They are particular in the 
choice of a breeding-place, at least some which*we would think 
suited for them, are passed or deserted, and others more 
unlikely are selected. We possess a reedy loch which was for 
many years a haunt of these birds, but the edges were planted 
and they left it; ten years afterwards, and when the plan¬ 
tation had grown up, a few pairs returned, and in time 
increased to a colony, when an artificial piece of water was 
made by damming up a narrow pass in an extensive muir, 
nearly two miles distant; thither the Gulls resorted the 
following spring, leaving their ancient ground; and they have 
been increasing in numbers for some years past.’
