🦇 Bats!

What you’ll learn

1. The Only Flying MammalUnderstand that bats are the only truly flying mammals and that their wings are made of long finger bones.Bats are mammals, meaning they have fur and drink their mother's milk as babies, yet they are the only mammals that truly fly. Their wings are actually their hands, with long finger bones connected by stretchy skin. There are over a thousand kinds of bats, from tiny bumblebee bats to big flying foxes, and most sleep by day in roosts like caves and hollow trees.
2. Seeing With SoundLearn how bats use sound and echoes to find and catch food in total darkness.Bats find their way in the dark using echolocation. They make high squeaks that bounce off objects and return as echoes, telling the bat where things are, how big they are, and how fast they move. Big, sensitive ears help catch these echoes, and bats use them to snatch bugs right out of the air with their wings or tail.
3. Fruit Bats and Bug BatsCompare bug-eating bats and fruit-eating bats and learn why bats eat so much.Most bats eat insects, and a single little brown bat can eat up to a thousand mosquitoes in one night, helping farmers and people. Fruit bats instead eat juicy fruit and use big eyes and noses to find it. A few bats fish, sip nectar, or drink a little blood. Flying is hard work, so bats eat huge amounts of food every night.
4. Living Upside DownUnderstand why bats hang upside down and how they grip, raise pups, and survive winter.Bats hang upside down because they cannot take off from the ground easily, so they drop into the air to fly. Their toe claws lock closed automatically, letting them hang without effort even while asleep. Baby bats, called pups, drink milk and learn to fly in a few weeks. In winter, some bats migrate while others hibernate in caves.
5. Bats Help UsDiscover how bats help people and nature by spreading seeds, pollinating plants, and eating pests.Bats do huge favors for the planet. Fruit bats spread seeds that grow into new trees, planting rainforests. Other bats pollinate night-blooming flowers, helping make bananas, mangoes, and agave. Bug-eating bats protect farm crops by eating pests, so farmers use less bug spray and sometimes build bat houses to welcome them.
6. Myths BustedCorrect common myths about bats and learn why bats need our protection.Many bat myths are simply untrue. Bats are not blind, since every kind can see. They are gentle and shy, not scary, and will not tangle in your hair. Bats are clean, grooming daily, and caring toward their families. Many bats are in trouble from lost homes and disease, so protecting their caves and forests helps them keep helping us.
