Why Animals Fly
Field notes: wings at work
Kererū fly between trees to eat fruit and spread seeds. Bats use flight to hunt insects after dark. Bumblebees fly between flowers to collect nectar and pollen; as they do, they can pollinate flowers. Bar-tailed godwits migrate from New Zealand to Alaska and back, travelling thousands of kilometres between feeding and breeding grounds. Flight can help animals reach food, find mates or nesting places, escape predators, or travel to suitable habitats. To stay in the air, a flying animal needs enough lift to balance its weight. Wings moving through air help create lift, while muscles provide the energy for flapping. Not every animal with wings flies: the New Zealand kākāpō is a flightless parrot. Its wings are too small and its body too heavy for powered flight.
