I just spent a couple hours at the Snoqualamie Wildlife Rec. Area (formerly
Two Rivers) near Monroe. While there I spotted a couple entaglements of
monofilament fishing line and strands of orange plastic twine in a tree near
the shore of Crescent Lake. Tangles of line in a tree are not uncommon in
fishing areas but the interweaving of orange fibers is unusual as is the
hanging bowl shape. On closer inspection I surmised these were Bushtit or
some similar nests.

While free roaming fishing line can be a life threatening hazard to some
species these birds have turned the tables and made it into an extremely
durable nesting material.

So here's a question: Do these birds ever reuse nests from previous
seasons? These two nests that I spotted will certainly last for a long time.
