A new study published this week in The Auk: Ornithological Advances shows that appearance alone is not enough to identify these hybrid zone birds: there is no single, intermediate «phenotype» or physical appearance common to all of the first - generation hybrids found, and birds from further backcrossed generations were often indistinguishable from the parent species.
