The World’s Most Abundant Bird

In Africa, south of the Sahara, there’s a bird that roams the countryside in flocks—hordes, really—of two million or more. They fly in such tightly synchronized masses they can be mistaken at a distance for clouds of smoke.

The birds are Red-billed Quelea. It’s estimated there are 1.5 billion of them — making them the most abundant of all wild birds.

The sparrow-sized Red-billed Quelea, which is in the weaver family, has a stout, seed-cracking bill. The birds are mostly brown, but breeding males have red and black feathered heads.

Quelea nest in enormous colonies. A single tree may be hung with hundreds, even thousands, of carefully woven nests. Single colonies can cover hundreds of acres, totaling tens of millions of birds.

Unfortunately, their tastes include cultivated crops, like millet.

In fact, the increased planting of cereal crops over the last fifty years may have dramatically increased the number of quelea.

But setting aside their taste for crops, the sight of a couple million Red-billed Quelea swirling in unison and creating ever-changing patterns in the air is one of nature’s most amazing spectacles.
