Small Eggs, Big Trade-offs: How Shorebirds Balance Clutch Size and Climate Risk

Why do some birds lay fewer, larger eggs? Shorebirds breeding in extreme environments have evolved surprising strategies to balance energy, risk, and reproductive success.

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.

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.
