The
Pacific Flyway is a major north-south route of
travel for
migratory birds in the Americas, extending from Alaska
to Patagonia. Every year, migratory birds travel some or
all of this distance both in spring and in fall, following
food sources, heading to breeding grounds, or travelling to
over-wintering sites.
Any given bird species travels
roughly the same route every year, at almost the same time.
Ornithologists and bird-lovers can often predict to the day
when a particular species will show-up in their area.
Along the Pacific Flyway, there are many key rest-stops
where birds of many species gather, sometimes in the
millions to feed, and regain their strength before
continuing. Some species may remain in these rest-stops for
the entire season, but most stay a few days before moving
on. One of these rest-stops, Boundary Bay, Canada, has been
listed as an Important Bird Area by the Canadian government in
recognition of its value to migratory birds.
