Could smell play a role in the origin of new bird species?
Date:3/23/2010

in sizes. Birds also lack the vomeronasal organ that many mammals (and reptiles) use to sense pheromones specifically.

Then came the discovery that sea-faring petrels can smell so well that they can identify other birds through sense of smell alone. This discovery kicked off a re-examination of several bird species, and preliminary results suggest smell in birds is a behavioral cue that has been overlooked for far too long.

"We still don't know how common it is for birds to use smell," Whittaker said. "The evidence so far suggests there is much for us to learn."
