Why Do Pigeons Thrive In The City?

Why Do Pigeons Thrive In The City?

Cities became the perfect backdrop for the pioneering pigeons' success. "Pigeons are naturally cliff-dwellers and tall buildings do a pretty great job at mimicking cliffs," Carlen told Live Science. "Ornate facing, window sills and air-conditioning units provide fantastic perches for pigeons, similar to the crevices found on the side of a cliff."

Another trait that makes pigeons more adaptable is their appetite. While other bird species have to rely on supplies of berries, seeds and insects, pigeons can eat just about anything that humans toss in the trash.

The pigeon's unusual breeding biology seals the deal: Both parents rear their chicks on a diet of special protein- and fat-rich milk produced in a throat pouch called the crop. So, instead of having to rely on insects, worms and seeds to keep their young alive — resources that would be scarcer in cities — pigeons can provide for their offspring no matter what, Portugal says: "As long as the adults can eat, they can feed their babies, too."
