Egyptian Free-tailed Bat (Tadarida aegyptiaca) lives in desert caves across Sub-Saharan Africa. It feeds on insects and spiders. Its conservation status is Least Concern.
Fascinating facts about the Egyptian Free-tailed Bat
- Its wings stretch 35.4 cm across, have an aspect ratio of 9.7 and a wing loading of 12.0 Nm⁻², making them long and narrow like a glider's. This aerodynamic package lets the bat cruise high above the ground, hunting insects over open terrain.
- Females carry a single pup for about four months before giving birth in December, then nurse until January while males wait another year to mature. This long, once-a-year reproductive schedule means each mother can devote all her energy to one offspring.
- It spans a patchy belt from Morocco across sub-Saharan Africa to India, Bangladesh and Sri Lanka, avoiding deserts and high mountains. The bat needs water sources and cliff faces, yet will also roost in roofs, temples or caves, showing remarkable flexibility in human-altered landscapes.
- In India's Rajasthan desert its menu shifts with the seasons, from beetles and flies in winter to termites dominating the monsoon. This flexibility lets the bat survive in environments where insect availability swings dramatically.
- Its nose is wired for smell: the cribriform plate has far more perforations than in other vesper bats, hinting at a keen sense of scent used in colony recognition. Strong odors at roost sites may help bats locate and keep track of their homes, a crucial skill for a species that can travel large distances each night.
