Same Species, Different Clocks: Migration That Shapes Reproductive Timing in Birds

Why do some birds get ready to breed while others are still preparing to migrate—despite living in the same place? The answer lies in how they sense time.

World Curlew Day: The Long Decline of Curlews, Now Fully Understood

Curlews are not disappearing unnoticed. The causes of their decline are now well understood, yet across flyways and landscapes, recovery remains limited and uneven — raising a harder question about the scale and persistence of our response.

What Do Shearwaters Eat? Uncovering a Mediterranean Food Web

What Do Shearwaters Eat? Uncovering a Mediterranean Food Web

DNA metabarcoding and stable isotope analysis reveal how two Mediterranean shearwaters share the same prey — and what that overlap tells us about life in a changing marine ecosystem.

Evolution or Plasticity? What the Hermit Thrush Reveals About Climate Change

Over four decades, a familiar North American songbird has grown smaller. But genomic evidence reveals that not all of these changes are evolutionary – some may simply reflect the remarkable plasticity of living organisms in a warming world.

Fabricated Birds: AI and the Future of Ornithology

Fabricated Birds: AI and the Future of Ornithology

When we generated a Shoebill that never existed, the realism was flawless – and unsettling. In an age where synthetic plausibility becomes effortless, ornithology must reconsider what authenticity means and how it is protected.
