The Insects That Are Killing Moose - Jim Robbins

Moose are big, powerful animals that most things wouldn't be able to kill them alone. As it turns out, it can take over a hundred thousand ticks to bring a moose down. Jim Robbins says that is suddenly becoming easier for ticks to do, with milder falls and shorter winters in the northern regions of the United States. There are a large number of causes harming moose, from pine beetles attacking the trees that provide them cover, to brain worms that live in snails. Robbins says that scientists aren't sure what to make of the declining numbers, but the sum of many weather-related changes combine to hurt the moose.
