I have long been a believer in the power of good photos for conservation. But they work even better when paired with a passionate, intelligent speaker. That’s why I was delighted to receive the below email from Shera, the Co-Executive Director at PROGRES Sulawesi & Conservation Scientist at the Wildlife Conservation Society Indonesia.

Members Making a Difference Worldwide

By Merlin Tuttle

3/17/2022

By illustrating scientific discoveries with spectacular photography, we equip others worldwide to overcome fear and inspire appreciation of the key ecosystem roles of bats. Our members have opportunities to contribute, both financially and personally, in making a measurable difference.

Recently, Partner Members Mindy Vescovo and Kathy Estes, funded and assisted me, our Workshop Advisory Trustee Daniel Hargreaves, our Program Coordinator Danielle Cordani, and Videographer Joey Chapman, in field photography and education in Costa Rica. We visited multiple locations including Fiona Reid’s Sylvan Falls and Harmony Hotel.

The major decline of traditionally abundant species, in Costa Rica and throughout Latin America, is cause for serious concern. In just a few days, we took a thousand new photos and recorded eight hours of video, covering 14 bat species. Many of these will soon be available in our photo gallery for use wherever needed.

Inspiring Bat Conservation Through Photos

4/9/2021

By Teresa Nichta

The Bat Scan Project provides photo documentation, enabling a growing number of conservation projects and exhibits worldwide to share the values of bats. These photos are also heavily used in children’s books, school reports, and in both scientific and popular publications. For example, the Smithsonian’s book, BATS: An Illustrated Guide to All Species, exclusively relied on nearly 400 of Merlin’s photos.

We’re delighted to share a few highlights from recent use.

Costa Rica’s Bat-Friendly Hotel

3/11/20

By Paula Tuttle

Merlin and I recently spent an especially productive week promoting bat conservation at the Harmony Hotel in northwestern Costa Rica. Merlin’s lecture, introducing the many values of Costa Rican bats, attracted a large and enthusiastic audience that included both hotel guests and community members.

Thanks to the owner’s passionate commitment to a healthy, sustainable environment, the hotel is a wildlife oasis in the midst of the small town of Nosara. Wherever possible, a lush profusion of native vegetation has been restored or introduced, serving as a magnet for animals, from howler monkeys, coatis and margay cats to large iguanas and an impressive variety of bats.

We quickly recorded more than a dozen bat species, belonging to five families, and introduced them to appreciative staff and guests. In fact, the proximity of multiple species posed the biggest challenge to use of a bat detector. The hotel may soon attract even more bats, as it intends to put up bat houses.

We were especially encouraged to learn of all the hotel’s progress toward environmental sustainability while maintaining top quality. The staff were outstanding. The food was healthy and delicious, and we thoroughly enjoyed the two evenings spent introducing the owners’ family and friends to the diverse array of bats found in their own yard.

Merlin has prepared a program on Costa Rican bats for the hotel to share with guests and in local schools, and we look forward to further collaboration.

Thai Adventures Part 4: Khao Chong Pran

2/19/20

By Merlin Tuttle

For me, our trip highlight was the visit to the Khao Chong Pran Cave in Ratchaburi Province. Nearly 40 years ago Buddhist monks who owned the cave had asked my advice. Their monastery relied on bat guano fertilizer sales for support. But in 1981 production was plummeting. Of course, and the monks wanted to know why.

Before dawn the next morning, my then young field assistant and interpreter, Surapon Duangkhae, and I discovered poachers using large fish nets to capture bats at the cave entrance. They were selling them to local restaurants. We hired two of the poachers to help us document the extent of the problem, then advised the monks to hire a game warden to protect their bats.

Thai Adventures Part 3: Cave Bats

12/26/19

By Daniel Hargreaves

We arrived at sunset at the OurLand Nature Reserve in Kanchanaburi Province, our home for the next 5 days. We quickly set up a few mist nets and a harp trap and were rewarded with a brace of lesser false vampire bats (Megaderma spasma) and several cave nectar bats (Eonycteris spelaea). Merlin took the opportunity to show the group how to train a bat. Unfortunately, the chosen bat was unusually difficult. However, just over an hour later it eagerly permitted Merlin to approach, enticing it to drink from a syringe filled with sugar water.

The next morning, we climbed 200 steps in search of roosting bats located in two caves above a monastery occupied by Buddhist shrines.

Initially, we captured a long-winged tomb bat (Taphazous longimanus) but as the group was looking at that one, I netted two bumblebee bats (Craseonycteris thonglongyai). Both were females weighing around two grams. They were delicately held by group participants while I explained the species’ anatomy, ecology, and conservation status.

Thai Adventures Part 2: Flying Foxes

1/21/20

By Daniel Hargreaves

Several hours after leaving the painted bat village, we arrived at the Wat Chantaram, Buddhist temple, in Ang Thong province. The monks protect Lyle’s flying foxes (Pteropus lylei) in the courtyard. We explained the ecology and diet of the species and how the group should approach the colony to minimize disturbance. Slowly approached, most of the bats remained calm allowing us to watch them grooming as they prepared to depart for the evening. The bats steadily increased their activity and their chattering became louder as they started to fly out in all directions, leaving the temple grounds in search of fruiting or flowering trees. As the bats were leaving, we could hear the monks chanting inside the temple providing a magical backdrop to the evening.

The following morning, we headed to Bang Pahan village in search of a second Lyle’s flying fox camp (a colony roosting site). The bats had set up camp alongside the river and after several attempts we discovered a spot where we could get closer.

Our focus was on photographing these roughly four-foot wingspan bats as they flew among roost trees. These weren’t as well protected, and something had made them nervous. They had a right to be, as some had wing membranes were perforated with holes from apparent shotgun pellets. Our group looked in awe as hundreds of these flying giants took to the sky, moving farther along the river.

Thai Adventures Part 1: Painted Bats

1/24/20

By Daniel Hargreaves

Following a 6-hour road journey from Bangkok we arrived at our first destination, the painted bat village. With only two hours left before sunset, we split into two teams. One assisted Merlin with setting up the flight studio. The other went to find a painted bat to photograph in the studio that evening. Team two headed out in carts pulled by two-wheeled tractors. They quickly spit into small groups furiously searching the dried leaves of banana plants for bats.

It wasn’t long before we found a single male painted bat (Kerivoula picta) hanging in a dried leaf about a meter from the ground. The bat had been banded for research, so although a good candidate, we didn’t disturb him and continued our search for more. Less than 200 meters away we found another male this time without a band. We quickly checked his weight at 4.6 grams (less than the weight of a U.S. nickel) and decided he was a perfect candidate for flight cage training.

This one was carefully placed in a soft bag, and to ensure picture and set authenticity we took the bat and the leaf he was roosting in back to the village. (There was no shortage of such leaves.) Leanne Townsend balanced precariously on the back of a moped, holding the bat and set material, as it sped to the village in order to setup for the night’s photography. As our Thai hosts prepared a banquet for their guests, Merlin got to work on the set, helped by an enthusiastic group of members fascinated to watch the master at work. As soon as the set was ready, we fed and watered the little star and released him into the studio. The group looked on as his shallow wing beats resembled that of a butterfly. He investigated every corner of the studio until he was sure there was no easy escape, then entered his now relocated roost.

Bats: An Illustrated Guide to All Species Gains Top Reviews and Sales

7/1/19
By Merlin Tuttle

The American version of BATS: An Illustrated Guide to All Species, published by the Smithsonian Institution, sold its first print run of over 5,000 copies in just three months. It also received high accolades from the science journal Nature and a prestigious Star Award from the Library Journal. The Library Journal verdict? “Far beyond the practical value of a guidebook, this is an important update to bat literature and one to savor, containing a wonder on nearly every page and proving that bats are indeed ‘intelligent, curious, comical, even essential animals.'”

The science journal Nature reported, “This guide by writer Marianne Taylor and bat conservationist Merlin Tuttle shines a light on the order Chiroptera, from the wee Kitti’s hog-nosed bat (Craseonycteris thonglongyai, a candidate for world’s smallest mammal) to the ‘megabats’ of the Pteropodidae family. Meshing deft scientific text with Tuttle’s sumptuous images, it’s a superb introduction to the baroque morphologies and flying prowess of these beguiling beasts.”

Experiencing Texas Bats

By Renee Anna Cornue
4/22/19

As MTBC’s Photo Collection Administrator, much of my responsibility lies behind a computer screen. I’d seen thousands (about 120,000 if we’re being real) of photographs from Merlin’s most-active field work days, preparing me for what to expect as much as photographs can. I’d seen mist nets, harp traps, banded bats, guano piles, and evidence of the bats’ incredible diversity.

Though fortunate to see Austin’s bats in a variety of ways, I’d never worked with bats first-hand. On this trip, I was most excited to step away from the desk and learn how bats are studied in the field, especially surrounded by knowledgeable and talented peers.

As with MTBC’s past adventures, our trip was a hands-on working trip with invaluable time and expertise contributed by leading colleagues from varied specialties. We were in the company of expert bat researchers, photographers, videographers, rehabilitators, consultants and passionate citizen scientists as we searched for some of the least known bats in the U.S.
