Where Are All the Baby Pigeons? The Mystery of the Urban Ghost Oisillon

It’s one of those urban mysteries we’ve all wondered about at least once: you see thousands of pigeons in the city, but you never see a baby one. No tiny, fluffy chicks begging for crumbs—only full-grown adults. Is it a glitch in the matrix? Not quite. The explanation is actually rooted in clever biology and strategic nesting.

The Secret of “Altricial” Species: Staying Hidden to Survive

The primary reason you don’t see baby pigeons is that they belong to a category of birds known as altricial (or nidicole). Unlike precocial birds—such as ducks or geese, whose yellow ducklings follow their mother as soon as they hatch—pigeons are born completely helpless.

An Extended Stay in the “Nursery”

While a common sparrow might leave the nest in under four weeks, a young pigeon (known as a squab) stays home for about 35 days. During this time, they transform from blind, hairless hatchlings into birds that are nearly identical in size and plumage to their parents.

By the time a pigeon finally decides to take its first flight into the city streets, it is already an “adolescent” that looks like a fully grown adult to the untrained eye.

High-Altitude Hideouts: Why You Can’t Find Their Nests

Even if you went looking for them, finding a pigeon nest is a challenge. Descended from wild rock doves that nested on steep cliffs, urban pigeons have adapted to use our architecture as a substitute for mountain peaks.

Pigeon nests are typically tucked away in:

Because they stay in these high-altitude fortresses until they are fully developed, they effectively bypass the “cute baby stage” in the eyes of the public.

Pro Tip: How to Spot a “Teenage” Pigeon

If you look closely at a flock, you can actually spot the newcomers. Here are the tell-tale signs of a young pigeon that has recently left the nest:

The Eyes: Adult pigeons have striking, bright orange or reddish eyes. Juveniles usually have dull, dark brownish eyes. The Beak: Look for a fleshy, grayish bump at the base of the beak (the cere). In youngsters, this is often smoother and lacks the bright white “chalky” appearance of an adult’s. The Feathers: You might still see a few wisps of yellow down sticking out through their feathers, especially around the neck or wings.

While they are a staple of urban life, pigeons are often classified as pests due to the damage their acidic droppings cause to historical monuments and the health risks they can pose.

To manage this, many cities now use contraceptive dovecotes. These specialized birdhouses allow officials to:

I had a pigeon make its nest on my apartments 16th floor balcony about 15 years ago. The nest was a disgusting mess and the babies were ugly little fuckers.

Same with sparrows. Or pretty much any bird that stays in their nest until grown, as opposed to those who start early to swim.

Birds stay young for a super short time, of which they are kept safe and secret from the likes of you.

Pigeons are known for growing up super fast, its like a month between hatching and leaving the nest. Before that, you aren’t seeing them because theyre in the nest and after that you probably just dont know what a juvenile pigeon looks like vs full adult feathers. Cities are also dangerous places so a baby pigeon that leaves the neat likely doesnt survive long enough to be seen before being eaten or something
