Canvasbacks

Male Canvasbacks can be distinguished from afar by their "dark at both ends and pale
in the middle" appearance. In both sexes, the long, sloping, black bill meets the fore-
head with no apparent break in angle. Canvasbacks begin to arrive in Vancouver in
October to spend the winter along estuaries, rivers and brackish lagoons. By
December they are present in full numbers, and by early April, most have departed
for their breeding grounds in central British Columbia.
These birds are clumsy on land owing to their rear-set legs, and they require rapid pat-
tering across the water to become airborne. They are most active in the early morning
and evening, when they dive up to 10 metres for pond vegetation, small clams and
crustaceans. During the day, most sleep in deep water with their heads tucked in their
back feathers.

Red-necked Grebes

Image
Red-necked Grebes spend each autumn and winter foraging in the salty marine waters off Vancouver. In the spring, they move inland to breed in freshwater lakes as far away as Alaska or Saskatchewan. Good places to observe these birds are from the Iona Island South Jetty and from the Stanley Park seawall, especially in September and April. Here, you can observe them diving below the surface of the water for sculpins, Pacific herring, minnows, shrimp and other aquatic animals.

Black Swift

The Black Swift is the largest North American swift, and it also outsizes all swallows in the Vancouver area. One of the positive aspects of approaching summer storms in Vancouver is that the low pressure systems force this bird low over the city where it catches flying insects. During warm, clear days, it is a challenging bird to locate because it forages at such a height that it appears as a mere speck against the blue sky. This bird breeds in B.C. but because it nests on remote, moist, rocky crevices only a few nesting sites have been confirmed. Black Swifts appear to time nesting so that their young can take advantage of the abundance of flying ants available in August and early September.

Black-bellied Plover

You will have to travel south of the city to the mudflats and fields of the Fraser River delta to see a Black-bellied Plover. Plan your visit at high tide when the plovers are pushed closer to shore. You may hear the plaintive pee-u-wee calls that help to keep flocks loosely together. Black-bellied Plovers are most common during migratory periods from late April through early May and from early August through September. Up to 1000 birds may remain over winter, but they are generally difficult to find. Like many other shorebirds, the Black-bellied Plover feeds in a typical stop-run-pick manner. On its arctic breeding ground it feeds mainly on insects, but its diet expands to include worms, small clams and crustaceans during migration.
