Greater Bulldog Bat (Noctilio leporinus) lives in tropical coastal waters across Central and South America. Its conservation status is Least Concern.
Fascinating facts about the Greater Bulldog Bat
- A single greater bulldog bat can scoop a fish up to 10 cm long from just 2.5 cm beneath the water surface, then stash it in its expandable cheek pouches while still in flight. This hunting feat is made possible by its enormous hind feet, 1.8 to 3.9 times larger than those of non-fishing bats, and a powerful, gaff-like claw that can impale prey. By keeping the catch aloft, the bat can continue scanning for more fish, dramatically boosting its foraging efficiency in the dim twilight over rivers and lagoons.
- When hunting, the greater bulldog bat emits a pure constant-frequency echolocation pulse that can last up to 17 ms, allowing it to detect the faint ripples a fish makes on the water surface. It shortens pulse duration and intervals as it drops toward a jumping fish. This acoustic precision lets the bat pinpoint prey.
- A greater bulldog bat's wings stretch a full meter, about three feet, from tip to tip, and 65 % of that span is formed by the elongated third digit. This wing architecture makes the bat's wings longer than its head and body combined, giving it a slow, wingbeat that can be used like oars when the animal swims. The ability to paddle with its wings lets the bat take off from water after a splashy catch.
- Female greater bulldog bats form long-lasting roosting groups that stay together for years, even when resident males change or the colony moves to a new hollow tree or cave. A single male may remain with the same female group for two or more reproductive seasons, while bachelor males live apart in small solitary clusters.
- Pregnancy in greater bulldog bats runs from September through January, with lactation beginning in November and lasting until April, and each female gives birth to a single pup after a roughly two-month gestation. Both parents care for the newborn, which stays in the roost for about a month before it can attempt sustained flight.
