I've been studying the Costa Rica book a lot and trying to puzzle out all the hyphenated combination names (e.g. Antwren, antshrike, shrike-vireo, shrike-tanager) and it seems like if Townsend's Solitaire had been named under similar conventions it would be Bluebird-thrush. Yes I know that bluebirds are technically thrushes. I chased the Solitaire that Kip had found at Warren Dunes. Brad pointed me in the right direction (a cedar stand I know they and Tim have been checking for years) and I didn't have to wait long for the bird to fly in. When I saw it flash through the bins my first impression was of a really brown mockingbird as a bird with a long tail with light edges flew away around a tree and perched out of sight. I had almost convinced myself I had somehow gripped a junco when it flew back.
As someone who doesn't go the UP very often, the only other time I've seen this bird in Michigan was a Livingston Co bird that I'm guessing was a lot of SE Michigan birders' state lifer from back in the digi-scoping days.
