cinematography, we planned to see if there would be measurable differences in the flight-initiating jumps of
Desmodus rotundus
and
Diaemus youngi,
the two vampires I would collect and bring back from Trinidad.
Not long after arriving in Trinidad and Tobagoâs capital, Port of Spain, I told Farouk what a pain it had been for us to machine the metal components of our force platform, get the electronics working just right, and then write the data-acquisition software. He stood by patiently as I tooted my own horn, polished it a bit, then tooted some more. Finally, I ran out of intricate gear to describe (or it might have been air).
âIt wonât work,â Farouk said, matter-of-factly.
âExcuse me?â I replied, my voice cracking like a twelve-year-old boyâs.
âYour experiment wonât work.â
Now I was getting visibly annoyed. Hadnât I just told him how much time, effort, and brainpower had gone into this project?
âOf course itâll work.â I was getting frantic now.
The Trinidadian said nothing.
âWhy wonât it work?â
Muradali put his hand on my shoulder and smiled. âBecause
Diaemus youngi
doesnât jump.â
âOh,â I replied, sheepishly. âRight.â
The light from Janetâs headlamp swept upward from the bottom of the empty elevator shaft (now below us) to the ceiling. âSo where are all theââ Her beam had stopped tracking abruptly.
Illuminated at the top of the chamber were three circular clusters, each composed of a dozen or so black silhouettes, arranged concentrically. They hung silently, reminding me of giant Christmas tree ornaments. Suddenly, one of the fusiform shapes unfurled, revealing wings nearly two feet across.
âPhyllostomus hastatus,â
Farouk whispered. âThe second-largest bat in Trinidad.â
âCrawling mother of Waldo,â I muttered, and Muradali threw me a confused look.
âDonât mind him,â Janet explained, keeping her light trained on the bats. âHe gets all scientific when heâs excited.â
Muradali nodded politely, then began assembling an object that looked suspiciously like a drawstring-equipped butterfly net at the end of a four-foot pole.
I shot him a quizzical look. âA butterfly net?â
âSwoop net,â Muradali corrected, handing it to Janet.
Farouk nodded toward the net, then shined his light up at a cluster of bats. âTo catch the ones closest to the elevator door, you lean out over the edge while someone holds your belt or backpack.â
Janet glanced up at the bats, then quickly shoved the net into my hands. Possibly sheâd had the same vision that Iâd just had, of tumbling down a concrete-lined abyss with nothing except years of rainwater, bat guano, and asbestos to soften the fall.
As I moved into the doorway, it was impossible to chase away the image of that poor woman, stepping off the solid concrete floor and into a bottomless pit of bat-shit soup. âThanks, hon,â I said.
Janet only smiled.
âWeâll leave these bats alone,â Muradali said, moving away from the shaft.
As we quickly followed him, I let out a breath I hadnât realized Iâd been holding. âCan we catch vampires like this?â I asked, suddenly feeling a bit braver and taking a few swings at some phantom air bats.
âNo,â he replied, picking his way through the debris. âToo smart.â
Later, the scientist explained that early efforts to eradicate vampire bats had resulted in the deaths of thousands of non-blood-feeding species. In 1941, Captain Lloyd Gates was placed in charge of protecting the American forces stationed at Wallerfield from the twin threat of mosquitoes and vampire bats. Gatesâs less-than-subtle response to the bat problem was to have his men use dynamite and poison gas in caves known to contain bat roosts. Flamethrowers became a popular alternative, but
