[Tweeters] Cowbird Songs: How?

[Dennis Paulson]

Hi Josh,

Cowbird song is genetically programmed, as it is in the vast majority of birds. Mostly the birds that learn their songs are Oscine passerine birds, the “songbirds.” Cowbirds are songbirds, but I guess along with their brood-parasitic habits, they have reverted to a preprogrammed song. Not that it’s any great shakes as a song.

I was watching one I had located by its song, over at North Seattle College, and it suddenly occurred to me that they don't have adult conspecifics around to learn from. So, how do they do it? Any ideas/references on the matter?
