Snowy Owls Have Invaded the Lower 49

Snowy owls are visiting from the Arctic.
Snowy owls have been
spotted on Vancouver Island and points south. This has the bird watchers
all aflutter as these beautiful birds belong in the Arctic. They are adapted
for life on the tundra with their thick feather coats and their white spotted
camouflage.
I haven’t seen any of the interlopers as of yet, but they
have appeared during the day and in unexpected places. Vancouver Island is
mostly snow free through the winter and trees are abundant. This seems to
confuse the birds as they are not used to trees. They have even been sighted
perching on the railings of the ferry that plies between the mainland and the island.
This is the second year that snowies have been showing up
this far south. Last year large numbers flew south across the continent. It was
surmised that they were looking for food. There had been a couple of good years
for the lemming population in the Arctic and the snowies benefitted from an
abundant food supply. They successfully raised larger than normal broods. Now
those youngsters are competing for food and territory and finding the pickings
pretty slim.
Some of the snowbirds have not fared well on the Island.
Rescue groups have been receiving distressed birds that are starving. The food
supply is different here and competition is ongoing. Those birds in residence
are not happy to see another at their food larder.
News reports from the city of Seattle state that snow owls
have occupied niches within the city. They have been observed attacking shore
birds and in turn, being mobbed by irate crows that want nothing to do with a
predator in their midst.
There’s always something new that Mother Nature has to show
us.
