There's nothing like bats to draw a crowd to the scorching Chihuahuan Desert in the late summer heat.
Several hundred people, myself and my son included, gathered a little before sunset one recent weekend outside the natural, open-mouth entrance to Carlsbad Caverns, eager to witness the nightly spectacle of bats spiraling out by the thousands and winging their way toward a buggy dinner.
With a pandemic disease killing millions of bats farther east, we wanted to see the impressive Carlsbad colony before it might be too late.
The caverns - home to perhaps 350,000 to 450,000 bats representing 16 species - were the big draw for us after having read Jules Verne's Journey to the Center of the Earth.
Throw in a nightly bat exodus, and the decision was made. We would visit at the hottest time of year in hopes of seeing a colony swelled in numbers by new-flying pups.
White-nose syndrome, the mysterious fungal bat-killer, has biologists everywhere on guard. The disease is believed to have spread from New York state, destroying an estimated 5.5 million bats since 2006 in the eastern U.S. and ÎÚÑ»´«Ã½, as well as the Midwest. The telltale sign of affliction: white powdery fungus on the nose, ears, wings and feet.
Fortunately at least for Carlsbad Caverns, white-nose syndrome, or WNS, has yet to make it this far west. National Park Service biologist Renee West said there's reason to believe Carlsbad may luck out since its bats tend not to hibernate in winter. (The disease appears to target hibernating bats.)
As they do every evening from May to mid-October, the crowds began gathering an hour before sundown at the stone amphitheatre next to Carlsbad Caverns' gaping mouth.
Glenn Reynolds, the National Park Service ranger serving as master of ceremonies for that evening's bat flight program, urged the crowd to snap one last picture before turning off all cameras, cellphones and other electronic devices. The gadget blackout, he explained, was to protect the bats.
Minutes later, the bats began to emerge, appearing as black shadows circling counterclockwise, first dozens, then hundreds, too many clumps to count in the dimming sky.
They headed toward the hills off to the right, occasionally passing right over our heads.
Not one cellphone rang. No flashes went off.
Rangers prowled the amphitheater, looking for potential violators and stray rattlesnakes. (One rattler had to be shooed off.)
As asked, the spectators were largely silent, with only the occasional whisper or baby's cry.
By the time darkness set in, only a few dozen diehards were left, peering into the night for signs of flight. Reynolds said afterward that his trained eyes observed thousands of bats launching into the pitch black. We adopted a bat for $5 before leaving, part of a research and education effort. We even got to name it.
Squeaky Toes, stay safe.
