In
spite of their common name, seagull, most gulls are shorebirds, seldom
venturing far out to sea, but often penetrating inland to scavenge on
tips, parks and reservoirs, and in towns and cities near the coast, are
a major problem. Gulls will follow the plough as readily as they follow
steamers and fishing vessels. There are six species which breed in the
British Isles, and many have increased their numbers so much that they
now are construed as nuisance pest birds (if there are any environmentalists
out there, a lot of this increase has occurred since the ban on collecting
birds eggs, but with an equivalent blame on the amount of rubbish that
the human species generate today). Such is their increase that they pollute
water, damage buildings, damage cars and attack other seabirds at nesting
sites (see the main pest bird page for damage that is done).
Gulls
are 11 to 27 inches long and have long wings. They're very good flyers
and experts at soaring (riding the wind without moving their wings). They
have white underparts, distinctive coloured legs and bills and their upper
parts vary from black to light grey. Many species have white markings
on a black background on the wings, these markings are known as "mirrors",
and some have a black or brown hood in the breeding season. Most gulls
find cliffs, stacks and uninhabited islands ideal for breeding, but colonies
of herring, common and black backed often nest in coastal dunes or on
bogs and marshes far inland. They lay three or four pear shaped eggs and
the chicks are well camouflaged as a defence against predators. Juveniles
soon leave the colonies and all species show distinctive plumage during
the first year of life. The largest of the birds take three to five years
to mature, during which they have several different types of plumages...confusing
isn't it...this can make identification difficult.
