How New World Blackbirds Spread From North America to Patagonia

Original: Songbirds on the Move: How New World Blackbirds Spread From North America to Patagonia

New research traces how New World blackbirds, a family of songbirds, expanded from their North American origins all the way to Patagonia at the southern tip of South America. The study follows the group's evolutionary dispersal across the Americas, mapping how one lineage of songbirds colonised a vast range of habitats over millions of years, from northern breeding grounds to subpolar regions.

Why now: Interest in the evolutionary history of a familiar bird family reaching from North America to the far south of South America.
