We have found, however, that this incredible diversity is underpinned by a hidden mathematical rule that governs the growth and shape of beaks in nearly all living birds. What's more, this rule even ...

A shared shape rule, the power cascade, governs most bird beak growth. It links modern birds with extinct dinosaurs.

While rare, a few birds we studied were rule-breakers. One such rule-breaker is the Eurasian spoonbill, whose highly ...

Traumatic damage to the germinal cells at the base of the beak can cause distortion, as can tumours and infections. However, simple overgrowth is probably the commonest beak problem seen at the ...

Bird beaks come in almost every shape and size—from the straw-like beak of a hummingbird to the slicing, knife-like beak of an eagle. We have found, however, that this incredible diversity is ...
