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

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.

Why Wait to Grow Up? Shorebirds' Delayed Maturity Tied to Coastal Living
Often seen roosting or foraging near coastlines, Oriental Pratincoles (Glareola maldivarum) are among the species analysed in the study. Their life-history strategies reflect the behavioural demands of complex habitats — an important factor in the timing of maturity. © Arkajit Chakraborty

Why Wait to Grow Up? Shorebirds' Delayed Maturity Tied to Coastal Living

Shorebirds that winter along dynamic coastlines delay their first return to breed, a strategy linked not to body size, but to the behavioural demands of tidal habitats — revealing new insights into how environment shapes avian life-history timing.

North America’s Bird Declines Reveal a Global Conservation Blind Spot

Common species are the backbone of ecosystems, yet new research shows they are declining at a scale that reshapes the conservation challenge. If familiar birds disappear, the loss will be both ecological and cultural — and it may already be happening faster than we think.
