These unusually dressed rodents are found around the state. The young are born with soft quills that quickly turn brittle after birth. Mammals are excellent protectors of their young. A mother bear with her cubs is not beyond aggressive behavior toward an intruder. Not all mammals are seen most often on the earth or in the water.
Bats are the only flying mammal in the world.
They are not birds. These insect-eating flyers migrate and hibernate. Seven species live in Pennsylvania, including the Indiana brown bat. This species has been placed on the endangered species list. Most bats produce only one young per year.
