Despite habitat strongholds in places like Illinois, white-nose syndrome continues to decimate the population.

The deadly white-nose syndrome is threatening the northern long-eared bat — one of Illinois’ 13 native bats — with extinction. The race is on to find a cure and protect what’s left of the population.

Studies show temperatures of -30°F will kill 98% of ash borer beetle larvae. Guess when Chicago was last that cold.

One of North America’s most common native bumble bee species, the aptly named American bumble bee, is on the ropes. Among the threats to its survival: competition from honey bees.

Four years after the rusty patched bumble bee was placed on the endangered species list, the U.S. Fish and Wildlife Service has released its final recovery plan for the insect, a plan critics say manages to go too far and yet not far enough at the same time.

The 240-pound, 100-year-old, nearly 7-foot-long sturgeon is making headlines. But fish that size used to be common in the Great Lakes and maybe, thanks to restoration efforts, they will be again.

The number of American bald eagles has quadrupled since 2009, with more than 300,000 birds soaring over the lower 48 states, government scientists said in a report Wednesday.

The U.S. Fish and Wildlife Service says the monarch butterfly warrants inclusion on the endangered species list but due to a lack of resources is being wait-listed behind higher-priority plants and animals.
