This guide is designed to introduce the seabirds and major colonies of Newfoundland and
Labrador. There are at least 311 known seabird breeding sites around the Island of
Newfoundland. Most are small with a few dozen or few hundred nesting birds. A few colonies
are of world significance and number among the planet's largest and most easily accessed
colonies. The Labrador coast is less studied, but there are over 1000 breeding sites, including the
world's largest razorbill colony.
Auks typically lay a single, large egg and feed themselves by diving after fish and other marine
animals. They use their wings for both flight and underwater propulsion, as well as diving to
great depths. Common murres have frequently been captured in nets set 200 meters underwater -
they are probably the deepest diving member of the auk family. Auks are very vulnerable to oil
pollution - in some parts of the world, tens of thousands have died in a day due to oil
spills.
Newfoundland and Labrador's provincial bird, the Atlantic puffin, is slightly smaller and stouter
than the murre and is one of our more colourful marine creatures. Its thick orange, yellow, and
grey bill makes it one of the world's most famous birds. Not only does it flu and swim
underwater, its razor-sharp claws allow it to dig deep burrows into the rich soil of seabird island.
At the bottom of this protective burrow it lays a single egg, which both parents look after until
late August or early September when the chick is ready for life at sea.
The gulls are among the world's most familiar birds. Although these long-winded soaring birds
are often called seagulls, some varieties have individuals that travel thousands of kilometres
from the ocean. Other gulls, like the kittiwake, are seldom seen near the coast once the breeding
season is past. Young gulls go through a series of colour pattern changes between hatching and
adulthood, and some gulls have different winter and summer plumage. Over 20 varieties of gulls
and terns have been reported from Newfoundland and Labrador waters. Field guides and field
experience are often necessary to make a reliable decision about the varieties of gulls seen in an
area. Our most commonly seen varieties are the herring gull (they nest all around the province),
the great black-backed gull (also called the saddle back, the world's largest gull), black-legged
kittiwake (also called the tickle ace - Newfoundland has the continent's largest colonies and
dozens of small colonies), ring-billed gull (also called the pond gull - numerous nesting sites
along the coast and in land) Arctic terns (dozens of coastal breeding islands), and common terns
(whom usually share breeding sites with Arctic terns). A few black-headed gulls, Caspian terns,
and perhaps a few other members of the gull family breed in low numbers on different coastal
sites, while over a dozen other varieties of gull and tern can visit the province during a
year.
The three types of jaegers can be distinguished by the shape of their central tail feathers. The
pomarine jaeger has rounded tail feathers, while the long-tailed jaeger's pointed, central tail
feathers can project more than 12 centimetres (4 inches) beyond the other tail feathers. The
parasitic jaeger has pointed central tail feathers projecting just a few centimetres beyond the
other tail feathers. There are other differences in colour, but the variety of colours within each of
three types makes it a challenge to distinguish between them without lots of practice.
A variety of other seabirds are also found around the coast. The common loon (great northern
diver, waabie) nests on lakes and along sheltered coastal areas in Terra Nova National Park.
During the winter, Newfoundland and Labrador's loons join the flocks of other seabirds on the
coast Here they are joined by loons from other parts of North America, including some
red-throated loons from the north.
This reserve is a must-see for nature lovers. In season, the gannets are joined by approximately
10,000 pairs of black-legged kittiwake and 10,000 pairs of common murres. Between May and
August, the mating behaviours, together with the laying of eggs and feeding of chicks, provide
visitors with intimate views in the life of a seabird. The reserve is also home to the world's most
southerly breeding site for thick-billed murres about 1000 pairs) and also provides opportunities
to view razorbills, black guillemots, herring gulls, black-backed gulls, double-crested
cormorants, and great cormorants Ravens, eagles, and other birds of prey are also drawn to the
area by the nonstop activities of the nesting seabirds.
This reserve, located just south of St. John's, is made up of four islands: Gull, Green, Great, Pee
Pee. These are home to the continent's largest gathering of Atlantic puffins (over 90,000 pairs)
and the world's second largest colony of Leach's storm-petrel. The reserve also features North
America's second largest kittiwake colony. In addition, there are a few dozen black-backed gulls,
razorbills, and black guillemots. Reports of Manx shearwaters on the reserve together with the
establishment of a small Manx shearwater colony, orth America's first, on Middle Lawn Island
off the Burin Peninsula lead some scientists to suspect that a few Manx shearwaters may be
found in an occasional burrow among the reserve's tens of thousands of puffin
burrows.
