Giant Kingbird
Tyrannus cubensis
The largest member of the tyrant flycatcher family, the Giant Kingbird is a powerful, heavy-billed endemic of the Cuban archipelago. This endangered species is known for its commanding presence and aggressive territorial defense in mature forest canopies.
What it sounds like
A loud, piercing, and metallic buzzy chatter, often transcribed as a sharp 'twee-twee-twee' or a raspy 'gi-zeeer'.
Field notes
- It is the world's largest tyrant flycatcher, reaching a length of up to 26 centimeters with an exceptionally massive bill.
- The species is known to be opportunistic and predatory, consuming not just large insects but also small lizards, frogs, and occasionally other birds.
- Like other kingbirds, it possesses a concealed orange-red crown patch that is flashed during territorial disputes or courtship displays.
- It is currently classified as Endangered by the IUCN, primarily due to the loss of its preferred primary forest and pine woodland habitats.
- Despite its size and aggressive reputation, it can be remarkably secretive and difficult to spot within the dense canopy of tall trees.
Habitat
Mature lowland forests, pine woodlands, and wooded areas near swamps or rivers with emergent tall trees.
Range
Endemic to Cuba, including the Isla de la Juventud and several northern cays of the Sabana-Camagüey Archipelago.
