Choosing Survival: Habitat Shifts in Wintering Taiga Bean Geese
Winter landscapes can appear rich in food, yet a few degrees below zero can render familiar feeding grounds unusable. For Taiga Bean Geese, survival depends on recognising when to abandon frozen pastures and seek alternative refuges. © Lars Petersson

Choosing Survival: Habitat Shifts in Wintering Taiga Bean Geese

When frost locks grasslands out of reach, Taiga Bean Geese turn to winter cereal fields to survive. New research shows how these fields become lifelines during the coldest days of winter.

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.
