Abstract
Why Birds of a Feather Flock Together
The biological determination of sociality, that is, why one might choose to associate with others and how many, has been unclear.
Goodson
et al.
(p.

) show that in gregarious finches, oxytocin-like receptors and their cognate ligand, mesotocin, are associated with group size choices. Receptor distributions clearly differentiate territorial species from flocking species. Furthermore, these compounds appear to play a role in affecting choice in affiliation in mammals, and thus may be conserved across evolutionary distant taxa.
