The Tallest Bird in the America’s!

The jabiru is the tallest bird found on the American continents. An individual can stand at heights of between 2.7 and 3.7m (9 and 12ft) tall with males being noticeably larger than the females.

These birds are found near water and will spend their day hunting for fish and other small animals. During the dry season they will also seek out dead animals.

Pairs remain together for life and will spend their time working on a nest which is sited in a tree or on top of a palm tree.

They are threatened by habitat loss and disturbance at their breeding sites.

Diet

What does the Jabiru eat?

The jabiru is a carnivore. They will feed on a range of reptiles, fish and amphibians. Their prey can be as large as a caiman.


This species has also been seen to scavenge for dead animals. They tend to increase this behavior during the dry season when their preferred prey sources are in short supply. By feeding on dead animals they help to clean up the bodies of water they inhabit.


Their large bill helps them to find food as they swoop it through the water to sense food.

Reproduction

How does the Jabiru produce its young?

Breeding takes place from December to May. As a result of the large investment of energy required to raise the chicks they will typically breed once every two years.


Pairs of jabirus are believed to remain together for life. They will perform displays to strengthen their pair bonds. Their displays are performed in the water at breeding grounds and involve wing flapping.


Their nest is a platform which is formed from sticks. It is typically located high in the trees and may be on the crushed top of a palm tree which can cause the death of the tree. They may make use of the same nest across several years.


In to the nest they will deposit a clutch of 2-4 colored eggs. Both the male and female are involved in the incubation period of the eggs.


Young are able to fly for the first time by 15 weeks old. Despite this they require care from their parents for a further three months.

Behavior

What does the Jabiru do during its day?

This species is able to fly. To aid in their take off they will perform a series of small hops. In flight they will hold their neck out in front of them. They may conduct large circles at height.


It is common to see this species in large groups.


While not considered vocal they do produce small vocalizations such as a hiss or fizz. They can also produce sound by clattering their bill.
