Two U.S. species I have heard duetting are Carolina wrens and great crested
flycatchers. The latter is particularly interesting, because duetting
mainly occurs in non-migratory species with long-term pair bonds. Great
crested flycatchers are highly migratory, though many other members of
their genus, *Myiarchus*, are tropical and sedentary.

Subject: [mou-net] plain-tailed wren duet research--- from Science Now
To: MOU-NET@lists.umn.edu
This article reports research on the duet singing of this wren species from
Ecuador. Given its name, could this be the only wren species without a
barred tail? Anyway there are links in the text to listen to the duet and
the single song.. also a link to the original journal article for those who
like neurology. I don't think there are any duetting bird species in N
America, but there are in Africa. I would guess their finding apply to all
such species worldwide, but who knows?
