Subject: Re: [Arlington Birds] Possible Nelson's Sparrow?
Hi Betty! Sounds like a song sparrow. I can hear where the PUC is getting
tripped up, by the trill at 2.3 secs. As much as I've enjoyed my PUC, I
wish I could tell it my habitat, ha. I'll get Nelson's sparrows
occasionally too, and nightly common loons that are actually firetrucks.
