Yesterday while birding at Narbeck in South Everett I heard quite a
commotion of high squeaky noises. I spotted what appeared to be a newly
fledged cowbird begging and subsequently being fed by a song sparrow. I have
a heard a lot of song sparrow noises in the past but never one like this
fledgling was making. The youngster was definitely larger than the parent
feeding it. The youngster was on a branch, no more than a couple feet off
the ground, where I usually see song sparrows. When I looked in my field
guides later I thought that the young song sparrows and the young
brown-headed cowbirds look similar.
Since song sparrows tend to nest close to the ground and cowbirds seem
like higher up kind of birds I was wondering if this was possible. Or is it
more likely that I confused the two younglings? Are song sparrow youngsters
noticeably larger than their parents?
