Pigeon: The city neighbour that finds its way home

The pigeon is one of the most familiar city birds: striding across squares, nesting under ledges, living alongside people for thousands of years. It looks ordinary, yet it has many remarkable abilities. Let's meet this city neighbour.

Its body

City pigeons are descendants of domestic birds, measuring about 29 to 37 centimetres. Their bodies are rounded with strong chest muscles, ideal for flight. Their bill is short and slender, and their feet grip nimbly, letting them stand steadily on narrow ledges. Their eyes sit on the sides of the head, giving a wide field of view.

Why it loves buildings

The pigeon's wild ancestor, the rock dove, originally lived on sea cliffs, nesting in the crevices of rock faces. So when people built tall buildings, those flat facades and gaps looked to pigeons like "man-made cliffs" — which is why they love nesting on buildings. Understanding this shows that pigeons are not "trespassing on purpose"; they are treating the city as their old home.

How it navigates

Pigeons are famous for finding their way home. Research shows they use several methods: memorising landmarks along the route, sensing the Earth's magnetic field, and even using smell. Together these clues help them find their way back. Even a chick's food is unusual — not seeds, but "crop milk", a nutritious fluid produced by the parents' crops.

A note for grown-ups

You could watch pigeons quietly in a square with a child, noticing how they walk and find food. Tell your child: pigeons like buildings because their ancestors lived on "cliffs". Helping a child "think from an animal's point of view" is a precious kind of empathy.
