Rare hybrid bird

Caption

This healthy, 1-year-old male offspring of a rose-breasted grosbeak and scarlet tanager is the first-ever documented hybrid of its kind. The two species have such divergent nesting preferences that they have been on independent evolutionary trajectories for at least 10 million years — until now.
