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.
In early August, we accepted a partnership invitation to develop a series of bat conservation and management training videos. Though growing numbers of biologists are studying bats, few have the breadth of experience essential to meet their widely varying conservation needs. Each species has unique requirements. In order to better share my nearly 60 years of personal experience, John Chenger founder of Bat Conservation and Management, and Janet Tyburec founder of Bat Survey Solutions, invited me to collaborate. They are providing video shooting and editing, featuring my narration and illustrations.
Four programs are now being edited. The first, tentatively titled “Win Friends, not Battles,” explains key approaches that have most effectively won long-term cooperation. The second features the worldwide importance of bats. The third addresses greatly exaggerated disease claims, and the fourth deals with assessing cave suitability for bats and special long-term management needs.
Under John’s guidance, we began field shooting on August 15, greatly aided by Teresa Nichta and John’s associate, Julie Zeyzus. For the next 10 days there was little time for sleep or even eating. On my birthday, we spent seven hours filming underground, a great antidote for thinking of getting old!
Illustrating the need for such education, one of the caves we visited in a protected nature reserve, had lost its entire colony of tens of thousands of cave myotis when fire protection permitted entrance blockage by vegetation. Another cave, also well protected by its owner, had overgrowth of an invasive, introduced plant that could have prevented restoration of a formerly large colony. It only took minutes to eliminate the threat.
During both weeks of our workshops, we encountered periodic rain showers, keeping the normally hot, dry-season temperatures far more comfortable than anticipated. The downside was that we had poor netting results on three nights during the second week. We shared the forest with some interesting characters, such as a black jaguar, which fortunately left us alone, though it likely observed our activities. This one was photographed on a trail camera near one of our netting sites.
We set up a triple-high mist net almost every night, both weeks.
During our two-week stay in Panama’s Cocobolo Nature Reserve, we recorded more than 600 bats of 53 species, more than half the total number known for the entire country. Additional species were netted nearly every night, including two on our final evening. Over our two-weeks of workshops, common vampire bats (Desmodus rotundus) and greater fishing bats (Noctilio leporinus) were participant favorites, though an incredible variety of fruit-, nectar-, and insect-eating species were seen. The hardiest of our group members often worked till dawn, bringing in a steady stream of species for portrait photos, especially during the first week. By the second week much more time was devoted to training bats to come on call, especially to locations where Merlin could photograph natural behavior, such as catching katydids.
The new group arrived successfully and with bells on for Week 2.
We have three bats in training. Merlin trained a hairy big-eared bat (Micronycteris hirsuta) for photography. Within 15 minutes it was flying to his hand on call, rewarded with meal worms. Janell Cannon, the famous author of Stella Luna, trained a white-throated round-eared bat (Lophostoma silvicolum) to eat from her hand. Her bat has a very calm temperament. Alexis and Amy trained a Niceforo’s big-eared bat (Trinycteris nicefori) for photography, a very sweet and eager gal.
We’re just finishing up an incredible first week at Cocobolo and already caught 44 species of bats, everything from fishing bats to vampires, not to mention a wide variety of fruit, nectar, and insect eaters. Merlin added 10 additional species to his collection! Pygmy fruit-eating bats were found roosting in leaves they had cut to form “tents”.
Chestnut short-tailed bats were all around camp, feeding on piper fruit.
We caught more than 20 Common vampire bats. Frontier campesinos keep a few livestock not too far away, explaining the presence of so many vampires. Most of these seem to have lots of personality, enabling Merlin to get this cool photo. The trip participants had loads of fun shooting videos of the vampires running around on the ground on all fours.
MTBC’s Bat Adventures in Panama Week 1 group started out from our base camp for an energetic hike to the top of the mountain ridge. Some did it in 3.5 hours, some 6.5 hours, and everything in between. My GPS said I hiked 19,190 steps (about 10 miles!) and burned 2,701 calories. Some will go back at night to net for bats in this cloud forest where they hope to find different species than the ones found at the Cocobolo Nature Reserve banana plants, and along the lower river forest.
Merlin and Daniel Hargreaves, co-founder of Trinibats, have teamed up to co-lead two weeks of bat workshops at the Cocobolo Nature Reserve in Panama. The reserve is over 1,000 acres located about halfway between the Pacific and the Caribbean on the narrow Isthmus of Panama, about 35 miles wide.
Taiwan’s Endemic Species Research Institute provided ideal facilities and hospitality thanks to Director, Kuo-Yun Fang’s and Research Fellow, Hsi-Chi Cheng’s enthusiastic support and the outstanding collaboration of their staff, especially Cheng-Han Chou (Shock) and Yu-chun Tan (Tammy).
