Find out which one of the following is different from the rest?

Parrot is the odd one out. Owl, Eagle and Hawk are all birds of prey (raptors), built to catch and tear live animals with hooked beaks and strong talons. Parrot is a seed, fruit and nut eater. Its hooked beak is for cracking food, and its zygodactyl feet are for climbing and holding food, not for killing prey.

The other three belong together:

• Owl (Strigiformes) is a nocturnal raptor with silent flight and forward-facing eyes.
• Eagle and Hawk both belong to Accipitriformes, diurnal raptors that hunt small mammals, birds and reptiles.

The core concept is classification by feeding ecology and taxonomy. Odd-one-out questions test whether you can group organisms by a functional trait. This links to the biodiversity and wildlife conservation theme in Environment, and to Mains questions on the role of predators in ecosystems.

Trap: Students pick Owl because it is nocturnal and looks different in habit, but the grouping here is by diet and predatory role, and Owl is a predator like the other two.
