13 Heaviest Flying Birds in the World

1. Andean Condor

The Andean condor is a magnificent bird found in the Andes mountains and adjacent Pacific coasts of western South America. As one of the largest flying birds in the world, you’ll be amazed by its massive size, which can reach up to 33 pounds in weight and boasts an enormous wingspan of up to 10 feet 10 inches. In fact, it’s often considered the most enormous bird of prey globally [source].

Living in the high cliffs of the Andes Mountains, the Andean condor takes advantage of its extensive 10-foot wings to catch the rising warm air, enabling it to fly with minimal effort [source]. While roaming the skies, these majestic birds use their keen eyesight to search for food, primarily consisting of carrion.

As an Old World vulture, the Andean condor plays a vital role in maintaining a healthy environment by removing dead animals and preventing the spread of disease. Additionally, these condors have fascinating adaptations, such as their bald heads, which allow them to keep clean while feeding on carrion [source].

Your journey to explore the world’s heaviest flying birds wouldn’t be complete without learning about the Andean condor’s incredible ability to fly without flapping its wings.

Research has unveiled that these massive birds can stay airborne for hours while barely flapping, relying on updrafts and their immense wingspans to keep them aloft [source].

2. Dalmatian Pelican

As you explore the list of the world’s heaviest flying birds, you’ll come across the Dalmatian Pelican, which is one of the largest flying bird species. This fascinating bird belongs to the Pelecaniformes family and can be found in parts of Europe and Asia.

The Dalmatian Pelican weighs between 23.5 and 29 pounds (10.5 to 13 kilograms) with an impressive wingspan that ranges from 10.1 to 11.3 feet (310 to 345 centimeters).

The Dalmatian Pelican boasts a unique appearance with its curly feather crests, a pouch hanging beneath its beak, and large, webbed feet. This bird is well-adapted for life in wetland habitats, where it feeds primarily on fish (source).

These pelicans are known for their cooperation when it comes to capturing their prey. In groups, they work together to herd fish into shallow waters, making it easier for them to scoop up multiple fish at once with their large beaks.

The female Dalmatian Pelican even receives help from her male counterpart when gathering materials like twigs, grass, and algae for nest building (source).
