EA # 9: Eastern Puma
The Eastern Puma is one of 14 animals that are endangered in the state of Pennsylvania. Its scientific name is Puma concolor. It is also known as a panther, cougar, and mountain lion.
Weight: 110-180 pounds (maybe one of your parents weighs this much?)
Height at shoulder: about 2 feet
Length, including tail: 5.5-8 feet
Lifespan: about 12 years old in the wild; up to 25 years old in captivity
The puma will eat a variety of animals, but its favorite food is deer. Most pumas live by themselves except during mating season.
Pumas are endangered because people hunt them, and they have lost a lot of their habitat because of people building more buildings all over the place.
Pumas purr just like house cats.
Most reasons for animal extinction.
EA # 8: Bald Eagle
It is the most famous carnivorous bird, probably because it is the symbol of the United States of America. Bald Eagles can live to be 30 years old, and they mate for life. Their nest is up to 13 feet tall.
On the Fish & Wildlife Service website, we found the following explanation about why Bald Eagles have become scarce:
"The greatest threat to the bald eagle's existence arose from the widespread use of DDT and other pesticides after World War II. DDT was sprayed on croplands throughout the country and its residues washed into lakes and streams. There, they were absorbed by aquatic plants and small animals that were eaten by fish. The contaminated fish, in turn, were consumed by bald eagles.
The chemical interfered with the bald eagle's ability to develop strong shells for its eggs. As a result, bald eagles and many other bird species began laying eggs with shells so thin they often broke during incubation or otherwise failed to hatch. Their reproduction disrupted, bald eagle populations plummeted. As the dangers of DDT became known, in large part due to Rachel Carson's famous book Silent Spring, this chemical was banned for most uses in the U.S. in 1972."
EA # 7: Indiana Bat
In Pennsylvania, the Indiana bat has become endangered because its hibernation sites have been disturbed. Indiana bats hibernate in caves.
The Indiana bat eats insects, especially pest insects, such as the gypsy moth and the alfalfa weevil. Actually, we have bats flying around over our yard around 8-9pm. They might be Indiana bats, but we haven't gotten close enough to see. They also eat mosquitos.
This species of bat has been endangered since 1967. There are 5 other bat species in the US that are endangered.

Endangered Species in Pennsylvania
EA # 6: Gray Wolf
The scientific name for the Gray Wolf is Canis Lupus.
The Gray Wolf is the largest member of the Canine family, and it is the ancestor of the domestic dog.
Size: 3.25-5 feet long
Weight: 35-130 pounds
The Gray Wolf travels in packs; each pack has a territory which they defend by patrolling the borders and leaving scent markings.
Females have litters of 4-7 pups. The pups nurse for about a month and then come out of the den to eat small amounts of food that were regurgitated by their parents and other members of the pack.
Gray Wolves eat tons of different kinds of prey, including moose and caribou that might be up to 10 times a wolf's weight.
Wolves are endangered mainly because they sometimes eat livestock, and ranchers and farmers try to kill them. But there are ways for ranchers to protect livestock that don't involve killing wolves, like better fences, alarms, and lighting.
