Bats (Order - Chiroptera) are the only mammals capable of "true" flight. They are nocturnal feeders and locate their prey - small to medium sized insects - by echolocation. Bats consume vast amounts of insects making them very effective pest control agents. They may eat as much as their weight in insects per day.

There are estimated to be about 1,100 species of bats worldwide, accounting for about 20 percent of all mammal species. About 70 percent of bats are insectivores. Of the remainder, most feed on fruits and their juices. Only three species sustain themselves with blood, some preying on vertebrates: these include the leaf-nosed bats (Phyllostomidae) of Central America and South America, and the two bulldog bat (Noctilionidae) species, which feed on fish. At least two known species of bat are cannibalistic, feeding on other bats: the Spectral Bat, also called the American False Vampire bat, and the Ghost Bat of Australia. One species, the Greater Noctule bat, is believed to catch and eat small birds in the air. Bats are present throughout most of the world; despite the cold weather, there are six species of bats in Alaska.

Some of the smaller bat species are important pollinators of some tropical flowers. Indeed, many tropical plants are now found to be totally dependent on them, not just for pollination, but for spreading their seeds by eating the resulting fruits. This role explains environmental concerns when a bat is introduced in a new setting. Tenerife provides a recent example with the introduction of the Egyptian fruit bat.



1) Nearly 1,000 kinds of bats account for almost a quarter of all mammal species and most are highly beneficial.
2) A single little brown bat can catch 600 mosquitoes in just one hour.
3) A colony of 150 big brown bats can protect local farmers from up to 18 million or more rootworms each summer.
4) The 20 million Mexican free-tails from Bracken Cave, Texas, eat 250 tons of insects nightly.
5) Tropical bats are key elements in rain forest ecosystems, which rely on them to pollinate flowers and disperse seeds for count- less trees and shrubs.
6) In the wild, important agricultural plants, from bananas, bread- fruit and mangoes to cashew, dates and figs rely on bats for polli- nation and seed dispersal. 7) Tequila is produced from agave plants whose seed production drops to 1/3,000th of normal without bat pollinators.
8) Desert ecosystems rely on nectar-feeding bats as primary polli- nators of giant cacti, including the famous organ pipe and saguaro of Arizona.
9) Bat droppings in caves support whole ecosystems of unique organisms, including bacteria useful in detoxifying wastes, im- proving detergents, and producing gasohol and antibiotics.
10) An anticoagulant from vampire bat saliva may soon be used to treat human heart patients.
11) Contrary to popular misconceptions, bats are not blind, do not become entangled in human hair, and seldom transmit disease to other animals or humans.
12) All mammals can contract rabies; however, even the less than half of 1% of bats that do, normally bite only in self-defense and pose little threat to people who do not handle them.
13) Bats are exceptionally vulnerable to extinction, in part because they are the slowest reproducing mammals on earth for their size. Most produce only one young a year.
14) Nearly 40% of American bat species are in severe decline or al- ready listed as endangered. Losses are occurring at alarming rates worldwide.


1) The world's smallest mammal is the bumblebee bat of Thailand which weighs less than a penny.
2) Giant flying foxes that live in Indonesia have wingspans of nearly six feet.
3) The common little brown bat of North America is the world's longest-lived mammal for its size with life spans exceeding 32 years.
4) 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.
5) The pallid bat of western North America is immune to the stings of scorpions and even the seven-inch centipedes upon which it feeds.
6) 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. 7) African heart-nosed bats can hear the footsteps of a beetle walking on sand from a distance of more than six feet.
8) Red bats, which live in tree foliage throughout most of North America, can withstand body temperatures as low as 23 degrees during winter hibernation.
9) Tiny woolly bats of West Africa live in the large webs of colonial spiders.
10) 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.
11) Frog eating bats identify edible from poisonous frogs by listening to the mating calls of male frogs. Frogs counter by hiding and using short, difficult-to-locate calls.
12) Vampire bats adopt orphans and have been known to risk their lives to share food with less fortunate roost-mates.
13) Male epauleted bats have pouches in their shoulders that contain large, showy patches of white fur, which they flash during courtship to attract mates.
14) 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.

Hi Haraprasan,

Now this is something really different! Very well presented with the close-up insert. Great shot showing all of these bats. Great notes too.


Interesting composition of the bats against the nice strong sky. The insert is a nice touch too. Excellent information about them. Well done.

We have a small family of bats living in an attic window. Unfortumately they don't keep up with the mosquitos though.


Hi Haraprasan,
Excellent presentation on these bats. Great job with the insert photo. Well exposed with nice colors and sharp detail. Amazing facts and details in your notes. Very well done.

Hello Haraprasan

Cool natural history picture! Those look like large fruit bats sometimes called Indian flying foxes (Pteropus giganteus).


Helllo Haraprasan !
What an interesting picture ! Very impressive to see all these bats in the same tree ! The blue sky makesa wonderful BG, making the bats stand out very nicely. It's good to have included a small picture of a flying bat. Very well done !

Hello Haraprasan,
Very interesting to see so many bats in the broad day light like this!
well captured and well seen
thanks for the wonderful notes too

Hi Haraprasan,
Splendid shot of these Bats hanging in such huge numbers. It must have been a wonderful sight and a bit scary too. The blue sky acts as a nice BG to let the subjects stand out clearly. Oh dear......so many. Excellent POV to portray this awesome scene and atmosphere and great notes. Very nicely composed. Kudos.

Hi Haraprasan,
Amazing shot,its interesting to watch so many bats on tree.
well composed shot with pov and details.
well done.

How very cool!!!
I used to do volunteer work at a bat cave near here and that definitely made me appreciate these amazing creatures.
Thanks for sharing these wonderful beings with us. Great shots!

Hello Haraprasan

A wonderful shot of these bats hanging from the tree.They look like fruit hanging there.Excellent detail and focus,the notes are tremendous and very informative.The lighting and colours are well done.TFS


Me sorprenden estas imágenes ya que en España no tenemos este tipo de mamíferos, solo algunos de pequeño tamaño en mi zona. Bueno el detalle de la foto pequeña y buen documento el de la foto mayor. Saludos Haraprasan.

Hi Haraprasan,
Fruit bats are my favourite animals as like rousettus in my nickname. Wonderful timing and nice capture. nicely composed. small frame also very nice capture. good notes to read.
thanks for showing us.
best wishes

Hi Haraprasan,
That's a very interesting shot. Very informative note.

Hi Haraprasan,

Like most amateur natur lovers I always thought bats only sleep in dark places such as caves...

Interesting notes and image.
