Very interesting, Greg. The River Ecology class from the Dungeness River Audubon Center had similar experiences to yours on Fri, Aug 24, while hiking along the Dungeness River near Gold Creek at only about 1250 ft elev. We saw both streaky juvenile juncos and spotty juvenile robins still begging from adults, including one barely feathered junco that looked like it had just left the nest. It's possible these birds were late clutches, but they may also be renesting attempts following earlier nesting failures, particularly your Swainson's Thrush. Seems really late.

Subject: [Tweeters] fledglings

I was hiking from Mowich Lake toward Spray Falls on Monday, about 5,000 ft. elevation. I observed an adult Swainson's Thrush foraging and feeding a recent fledgling - three trips in about eight minutes. A little farther down the trail I witnessed two fluffy fledgling Pacific Wrens being tended by two foraging adults. Since the snow lingers so long up there and it was August 20th (not really "Spring"), might I assume that in both cases there was only one brood from those particular adult birds this year? Would appreciate any thoughts on the matter...
