Re: Passerine Sp. at Fort Boise WMA – Any Thoughts on Audio Identification? Maybe a Grosbeak?

I agree with Jay – there are some signature phrases for Bewick’s Wren, in particular the bell-like slow trill, “ding-ding-ding-ding,” that appears several times (at 8 sec, 16 sec, 38 sec). I think that’s what Jay is calling “Song Sparrow-like,” but I find it even more similar to the ending of Black-throated Sparrow. The rest of the song is easily within the varied repertoire of Bewick’s Wren, but in my experience virtually every Bewick’s Wren, in the west at least, throws in that bell-like slow trill at random intervals during its song.
