Hi Tweets,

In southwestern BC just across the Strait of Juan de Fuca opposite the
Olympic Peninsula, they've come and gone. To summarise the information in
Birds of BC, vol 3, p 358 (Campbell et al):

Western Bluebirds Sialia mexicana used to be a common resident in SW British
Columbia as well until relatively recently, but declined catastrophically in
the 1960-1970 period on the BC mainland while still maintaining population
on southern Vancouver Island, even increasing population there during a
nest-box program. Numbers then declined drastically and "The nest box
program has been abandoned as a failure due to loss of habitat, competition
with European Starlings and House Wrens, and a decreasing nucleus of
breeding birds (Pollock 1990, 1991, 1992, 1993, 1994). Today the Western
Bluebird seldom occurs anywhere in the Georgia Depression."

And you wonder why it's called the Georgia Depression.
