What Is The Most Common Bird In The World?

Red-Billed Quelea

The most common bird in the world is the domestic chicken (Gallus gallus domesticus). In 2018 it was estimated that there were around 23.7 billion chickens in the world, up from 14.38 billion in the year 2000.

Chickens are mainly kept for egg-laying and meat with China alone producing 529 billion eggs in 2017. The world’s second leading egg producer, the United States, produced 106.7 billion eggs in the same year and 19.71 million metric tons of meat in 2019.

However, the most abundant wild bird is the red-billed quelea (Quelea quelea), a sparrow-sized bird in the weaver family with a population of about 1.5 billion breeding birds.

Also known as the red-billed weaver or red-billed dioch, the red-billed quelea is native to sub-Saharan Africa and can be found in tropical and subtropical areas with a semi-arid climate although it avoids forests, deserts, and colder areas such as those at high altitudes.  

Red-billed queleas have mainly brown plumage but during breeding season 75% of males develop a black facial mask bordered with pink or rust coloured feathers. Occasionally they will develop a white mask bordered with black. They have a stout, cone-shaped bill which is red in females outside of breeding season and males all year round, and orange or yellow in females during breeding season.

Their bills have evolved to crack open seeds which make up the majority of their diet, preferring grains of 1-2 mm in size, such as wild grasses and rice. Due to their sheer numbers, red-billed queleas can cause extensive damage to cereal crops including millet, teff, barley, and oats, and due to this they are sometimes known as ‘Africa’s feathered locust’.

They are sociable birds and feed in flocks of millions of birds. They usually feed on the ground and as birds at the back of the flock run out of food they will fly over the birds in front to reach a fresh feeding area which gives the impression of a rolling cloud.

Governments in a number of African countries have attempted to lessen or eradicate the population of the red-billed quelea by spraying avicides or detonating fire-bombs on colonies during the night. However, these have been largely unsuccessful and population management is now focused on areas most likely to attack vulnerable fields.
