Here is a 40 second sound clip from a happy bird that I heard, but never saw at first light this morning. I am in suburban Philadelphia, PA and it was raining lightly with the temperature in the mid-40s. It reminds me of a robin in certain ways, but with an extra warble- at least I think that's the word for it. I'll just apologise ahead of time in case it's some kind of sparrow. All comments welcome. Thanks.
