Some Amazing Bat Trivia

  • The world's smallest mammal is the bumblebee bat of Thailand, weighing less than a penny.
  • Giant flying foxes that live in Indonesia have wingspans of six feet.
  • The common little brown bat of North America is the world's longest-lived mammal for its size, with life spans sometimes exceeding 34 years.
  • Mexican free-tailed bats sometimes fly up to two miles high to feed or to catch tailwinds that carry them over long distances at speeds of more than 60 miles per hour.
  • The pallid bat of western North America is immune to the stings of scorpions and even the seven-inch centipedes upon which it feeds.
  • Fishing bats have echolocation so sophisticated that they can detect a minnow's fin as fine as a human hair, protruding only two millimeters above a pond's surface.
  • African heart-nosed bats can hear the footsteps of a beetle from more than six feet away.
  • Frog-eating bats distinguish between edible and poisonous frogs by listening to the male frogs' mating calls. The frogs counter by hiding and using short, difficult-to-locate calls.
  • Red bats, which live in tree foliage throughout most of North America, can withstand body temperatures as low as 23 degrees Fahrenheit during winter hibernation.
  • Tiny woolly bats of West Africa live in the large webs of colonial spiders.
  • The Honduran white bat is snow white with a yellow nose and ears. It cuts large leaves to make "tents" that protect its small colonies from jungle rains.
  • Vampire bats adopt orphans and have been known to risk their lives to share food with less fortunate roost-mates.**
  • Male epauleted bats have pouches in their shoulders that contain large, showy patches of white fur, which they flash during courtship to attract mates.
  • Mother Mexican free-tailed bats find and nurse their own young, even in huge colonies where many millions of babies cluster at up to 500 per square foot.

Chiropterophily: Bat Pollination

I see you! Geoffroy's tailless bat (Anoura Geoffroyi) - photo by Nathan Muchhala Ever since coming across this word, I can't stop saying it: chiropterophily. Chiropterophily, or pollination of plants by bats, is very common in the tropics. Hundreds of tropical plant species are exclusively or at least partly pollinated by nectar-feeding bats. Many tropical flowers are night-blooming, specializing in attracting bats. Bat-flowers are typically white, cream, or pale green in color, making them easier to see in the dark. They usually have a musky, fermented odor - like that of the bat - or sometimes a fruity odor. They have a large, sturdy, open shape with long, bushy anthers so that the bat's head and chest get coated in pollen when it visits. In return for the bat pollinating the flower, the flower provides the nectar that these high-energy flying mammals need.* Tube-lipped nectar bat (Anoura fistulata) - photo by Nathan Muchhala Nectivorous bats have both good eyesight an

Eyeshine in Nocturnal Animals

Peters' Epauletted Fruit Bat (Epomophorus crypturus), Kruger National Park - photo by Peet van Schalkwyk Have you ever noticed how under certain lighting conditions some animal's eyes seem to glow? Animals that are nocturnal hunters - and a few of them that are not - have something called eyeshine . Eyeshine is the light that we see reflected back from the animal's tapetum lucidum (a membrane behind the animal's retina). Light enters the eye, passes through the retina, strikes the reflective membrane, and is reflected back through the eye toward the light source. This phenomenon makes the most of what little light there is at night for these nocturnal creatures. a moth with pink eyeshine Humans can display the red-eye effect in flash photography, but we do not have a tapetum lucidum , and thus, do not have eyeshine. Eyeshine is best observed by wearing a head lamp or holding a flashlight at eye level against your temple because the light is reflected right back into

Leaving Bosque del Cabo

January 4, 2010 We woke right before dawn. The howler monkeys were especially vocal this morning (or perhaps we just slept through the loud parts the previous mornings). We got ready then had a super quick breakfast of granola and fruit. The staff packed us some sandwiches for later. I selected avocado; Nick selected the pb&j deluxe. Eric drove us to the small, regional airport in Puerto Jiménez. It was a quiet ride; we were sad to go. We were fortunate to be able to stay 6 days; but even in this amount of time, we didn't do everything we wished to, like hike down to the beaches, hike to the waterfalls and the take the zipline tour. As we continued down the road, we passed the signpost to Lapa Rios, the lodge we had stayed at the previous year. Which was better? I hate to make such comparisons, as each of these places holds a special place in our hearts. Lapa Rios was the climactic end to our very first trip to Costa Rica. It was during the rainy seaso
