If you remember elementary school science, you know that mammals are warm-blooded vertebrates that have fur or hair, breathe with lungs, and give birth to live young that they nurse. There are more than 5,000 species of mammal in the world, but fewer than 40 commonly found in Westchester County.

Some mammals–such as bears, bats and some rodents–hibernate in the winter, but many can be seen throughout the year.
