Maryland Department of Natural Resources (DNR) biologists have confirmed that bat carcasses collected from a cave near Cumberland on March 5, 2010 were infected with White Nose Syndrome (WNS).
“This is the first confirmed WNS case in Maryland. DNR will implement a regimen of restricted access and decontamination procedures for all known bat locations,” said DNR Veterinarian Cindy Driscoll. “DNR has also encouraged the owners of the Cumberland cave to prohibit all access to the site.”
The four dead bats collected at the cave by DNR biologists were submitted to National Wildlife Health Center in Madison, Wis. for diagnostic evaluation of suspected WNS. The bats tested positive for Geomyces destructans, the fungus known to be the causative agent of skin lesions observed in WNS-affected bats. The center has confirmed the characteristic lesions of WNS in these bats.

Storms threaten butterflies' winter rest in Mexico. . . A loss of forests and food sources has for years thinned the number of monarchs coming to Mexico. But scientists fear that a new pattern of punishing winter storms may mark the start of an irreversible decline of the transcontinental migration.
In early February, normally one of Mexico's driest months, 15 inches of precipitation fell on hilly central regions, battering monarch reserves with snow, sleet and freezing rain.
Fewer butterflies arrived this year than ever before, and as many as half of them are thought to have perished in February.
. . . "Will butterflies come back? Yes, but the numbers will be so vanishingly small that it may mean the end of this spectacular phenomenon," Taylor added.

Crow deaths investigated
A rash of crow deaths in Florence has caught the attention of health and wildlife officials.
Florence city spokesman Phil Stevens said employees of the city's street department collected 15 dead crows Thursday.
. . . "With no one reporting seeing any sick birds, only dead ones, my initial suspicion is the deaths were caused by something that was fast-acting, like a pesticide," Hudson said. "Usually, when it's a virus or disease that causes the death, there will also be sick and dying birds in the area."
