We also get dozens of papier mache' wasps nests under our very wide and
extensive eaves in Silverdale. They never reach a mature stage because of
predation by the following species (that we've observed over the years):

Black-capped Chickadees
Chestnut-backed Chickadees
Dark-eyed Juncos
American Robins
Song Sparrows
Pacific-slope Flycatchers (while nesting under said eaves)
Northern Flickers!
Steller's Jays (probably your "bluejays" If they are Scrub Jays, please
report them to <KitsapAudubon at avisys.net>)

The smaller of the above birds also clean out the spider webs of spiders
and their prey, and Rufous Hummingbirds take away large amounts of web.

The wasp nests serve as a season-long food source for our birds because
they no sooner get ravaged than the wasps build again.
