Series 1
This series demonstrates COURTSHIP BEHAVIOR? during which an
Adult NECO inserts its head into the other NECO's throat
in a consensual act.
A Likely Explanation: From Bryant Olsen
"Rich,
I propose that it may actually be courtship behavior. Many species of birds will exchange food as part of their courtship,especially males feeding females. I think it helps let the female know she will have a good provider for her during incubation and for the young."
