Wild at the Point: Shore and Sea Birds. Part 2
Published on Fri, Apr 23, 2010 by Peter Hamilton, Lifeforce Founding DirectorRead More Wild At The Point
This
article concludes our two-part report of the diversity of shore and sea birds
living in or migrating through Point Roberts at this time of year. While many
others can be seen I have listed mainly the 40-plus species that I have seen
this fall. I hope that it will inspire you to challenge yourself and friends by
seeing how many you can each find and photograph.
In the same family as upland game birds, such as Ring-necked
Pheasants sometimes spotted running along the beach, are Loons, Grebes,
Cormorants and wading birds such as herons.
There
are three types of cormorants – Double-crested Cormorant, Brandt’s Cormorant
and Pelagic Cormorant. The latter two have dark plumage and they can be
distinguished by the pencil-thin black bill of the Pelagic as compared to the
Brandt’s thicker bill. The Double-crested has orange at the lower base of the
bill, longer wings, tail, and flies with a crook in the neck. The Pelagic can
leap from the water to fly while others must run along the water to gain speed.
We
have Western Grebe, Horned Grebe and Red-necked Grebes. The Western has a long
neck with distinct white throat and black behind. Their population has
drastically declined. Horn Grebes get their name from the golden “horn” plumage
from eye to back of head when breeding. Non-breeding color is dark gray with
white cheeks. They can stay submerged for three minutes and dive to depths of
150 meters. Red-necks carry their young on their backs. During breeding they
have a reddish-brown neck that is dingy gray when not breeding.
There are Common Loons, Pacific Loons and Red-throated Loons. When breeding both male and female
Common Loons have a dark collar on the lower neck. They are common in winter
but uncommon local breeders as they breed across North America to Iceland.
Pacific Loons are gray and white during winter with silver-gray crown and nape
with vertical whiter stripes on both sides of the neck. The red-throated has a
red throat with dark back when breeding. They are white on face and front of
throat and gray back with white speckles. The Red-throated Loon is the only
loons that can take flight from land.
Great
Blue Herons are common year round in the region. They nest in tall, dead or
dying trees in colonies. They eat a varied diet from fish to rodents.
Family
– Jaeger, Gulls, Terns – Alcids (murres, guillemot, murrelet, auklet)
Pigeon
Guillemot shows a very different winter plumage from
mostly dark blackish brown
bodies with orange feet to the mostly white with black wing tips.
Common
Murre also change dramatically from their dark brown head and throat to white
throat and lower face during non-breeding. They have a dark line behind the
eye.
California
Gull, Ring-billed Gull, and Mew Gull can all be seen. The most frequent are
Glaucous-winged Gull. The most fun to watch are the Bonaparte’s Gulls who are
the only gull that can synchronize flight as do Black Turnstones. The fall
migrant, Parasitic Jaeger, chases them in flight to get their regurgitated
food. Jaegers eat lemmings and small birds when in the tundra. They breed in
arctic tundra and winters on both tropical and subtropical seas.
Caspian
Terns, identified by their screeching kaa yarrr, sounds differ than common
tern. They fly high and plunge-dive for fish that can be several feet below the
surface.
When
Rhinoceros Auklet forage, the upwelling of fish they instigate is a major
attraction to other birds. They excavate nests on grassy, bushy slopes above
the shoreline.
Rail
and Coot – Shorebirds (Oystercatchers, Sandpipers, Sanderling, Turnstone)
It is
interesting that the Killdeer, known to feign broken wing in fields and parking
lots, belongs to this marine family. They can be seen on the beaches catching
insects.
Mixed
groups of Sanderlings and Black Turnstones can be quite friendly. If I am
sitting on the shoreline they will pass by within a few feet. Some will stop
and do some human watching. They haven’t considered me a threat as the more
wary Turnstones chose not to call out in alarm. Sanderlings stay from August to
May then travel 13,000 kilometers to reach spring nesting grounds in Arctic
tundra.

Respect
and Enjoy Wildlife
While
we marvel at the wonders of wildlife please don’t approach, feed or try to
touch. They may look cute but they can cause severe injuries. Bread and junk
food can kill them. So respect and enjoy them from a distance.
