Sea & Shore Birds of the West Coast |
The Seabirds nest in colonies which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, in which they cross the equator or circumnavigate the earth. They feed both at the ocean's surface and below it. The plumage of most seabirds is less colourful than that of land birds, being mostly black white and grey. Seabirds have four basic feeding strategies for feeding at sea: surface feeding, pursuit diving, plunge diving, and predation of higher vertebrates. Like many birds, seabirds usually migrate just after their breeding season, sometimes crossing the Equator. Some birds have been recorded to make an annual round trip of 64,000 km. Some species do not have a migration pattern, but drift southwards as the winter approaches. Some shorebirds will only to feed every 2,000 km during their travels, making their feeding and resting time detrimental. Any human, or animal disturbances (such as dogs chasing them on the beaches) causes a great deal of stress on the seabirds. Here is a detailed list of the most common Sea and Shore Birds found on & off the West Coast of Vancouver Island, British Columbia, Canada.
