The
turkey vultures that Manning watched in the Gulf Islands are part of a
population that migrates annually to southwestern Canada and the adjacent
United States from as far south as Venezuela and Colombia. The Atlas of the
Breeding Birds of British Columbia estimates that up to 300 pairs may breed in
the province.
The
species’ ability to efficiently use their wings to glide the thermals allows
them to travel vast distances across a variety of landscapes and temperatures.
That makes them more resilient to climate change, with the potential to
increase their northern range as temperatures warm. --- Hakai
