There is also an article about these same two species nest sharing.

I believe this is the journal of the Georgia Ornith. Soc.

Subject: [va-bird] Nest sharing
Mary Reid Barrow's note on interspecies nest sharing is intriguing. Yaa
wonder what sort of reproductive pressures drive such a phenomenon. I've
never heard of this although I have heard of same species sharing nests.
This Cardinal-Robin nest sharing might deserves photographic documentation
and publication in a scientific journal, if someone has the time and
interest. Intrigued by the matter I did a quick Google search and located
few anecdotal records...scaup
1) Fournier, M. A., and J. E. Hines. 1996. Nest sharing by a lesser
and a greater scaup. Wilson Bull. 108:380-381.even
2) ..."Some owls recycle abandoned nests of hawks or crows, and there's
a record of nest sharing by a Red-shouldered Hawk that sat on a mixedclutch
of eggs at night while a Barred Owl incubated the same nest by day." inemail to va-bird@xxxxxxxxxxxxx. To unsubscribe, send email to
