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.
