Fascinating facts about the Broad-eared Free-tailed Bat
- A single broad-eared bat can weigh just 11 g, about the mass of two teaspoons of sugar, yet its wings are hairless and translucent, letting it slice through night air with barely a whisper. Measuring about 10 cm from nose to tail tip, it fits on the palm of a child's hand. Its ears are so wide they meet at the forehead, a design that funnels echoes straight to its ears for precise sonar. This tiny, feather-light hunter shows how evolution can trim excess weight while sharpening sensory tools, enabling it to hunt insects on the wing.
- Broad-eared bats inhabit elevations from sea level up to 1,700 m, but they are most common below 500 m, thriving in tropical forests, scrubland, cerrado, and even urban areas. Their ability to live from coastal plains to cloud forests shows a remarkable ecological versatility, allowing them to exploit a wide range of insect prey across diverse landscapes and making them a key insect-control agent in many ecosystems.
- Broad-eared bats can gather in roosts of up to a thousand individuals, and in Tamaulipas colonies of several thousand have been reported squeezing into a single cave. They huddle in rocky crevices during daylight, forming dense clusters.
- A newborn broad-eared bat opens its eyes within a few hours of birth, weighing only about 3 g,.
- During the rainy season, each female broad-eared bat gives birth to just one offspring, timing the event between June and July in the northern part of its range.
