I heard a particular bird song several times this morning. I did not know the species of bird, so this evening I listened to my Bird Songs of Alaska CDs to see if I could find the song. It sounded like one of three different birds, dark-eyed junco, chipping sparrow or orange-crowned warbler. The orange-crowned warbler does not generally winter in Southeast Alaska, and the chipping sparrows are listed as rare in this part of the state, so it seems likely that it was a dark-eyed junco. There are noticable differences in the song, so further listening and comparison should help me decide whether this conclusion is correct.
