Evolution and Taxonomy

From feathers to flight, speciation to song, the Evolution section explores how birds became what they are today. We cover the latest research on avian phylogeny, genomic change, trait development, and adaptive radiations—bringing clarity to the origins and diversification of bird life across deep time. Whether it’s a newly resolved lineage or a genomic insight into migration, this is where bird evolution takes shape. Tag image credit: © John J. Harrison, All rights reserved

Bound by Coastlines: Genetics and the Hidden Structure of Mexico’s American Oystercatchers
American Oystercatchers along the coast of north-western Mexico inhabit a landscape shaped by strong site fidelity, where breeding populations remain closely tied to specific bays and shorelines despite their ability to travel long distances.© Rain Saulnier

Bound by Coastlines: Genetics and the Hidden Structure of Mexico’s American Oystercatchers

Genetic evidence from Mexico’s coastlines reveals that American Oystercatchers are far less mobile than they appear, shaped by loyalty to place and hidden evolutionary boundaries.

Cormorants: Evolutionary Failure or Underwater Mastermind?

Cormorants: Evolutionary Failure or Underwater Mastermind?

Cormorants are often labelled evolutionary misfits for having partially wettable feathers – hardly ideal for a diving bird. Their design is far from flawed. It is a finely tuned adaptation that reveals an unexpected path in the evolution of underwater hunting.

Born in Isolation: The Australian Origin of Songbirds

Oscines – true songbirds – make up nearly half of all bird species alive today. A new study confirms that their evolutionary roots trace back to Australia, offering powerful new insight into one of the greatest radiations in avian history.
