- 3. MAMMALS FACTS - All mammals are viviparous, except for monotremes, which are oviparous. - All mammals are vertebrates. ECHIDNAS live in parts of Australia and New Guinea. - Mammals can be CARNIVORES, HERBIVORES OR OMNIVORES. They have different types of teeth depending on the food they eat. - Baby mammals drink their mother's milk until they can find their own food. - All mammals breathe with their LUNGS. - Most mammals have FUR or HAIR to keep them warm. - Most mammals have 4 LEGS and move ON LAND. Some mammals have FLIPPERS and move IN WATER. Only one mammal has WINGS and can FLY. ELEPHANTS ARE THE LARGEST LAND MAMMALS. THEY ARE HERBIVORES. GIRAFFES ARE THE TALLEST LAND MAMMALS. THEIR NECKS ARE LONG SO THEY CAN EAT LEAVES FROM TALL TREES. DOLPHINS USE FLIPPERS TO MOVE IN WATER. THEY BREATHE THROUGH A HOLE AT THE TOP OF THEIR HEADS. THEY ARE CARNIVORES. BATS ARE THE ONLY MAMMALS THAT CAN FLY. MOST BATS ARE NOCTURNAL, SO THEY ARE ONLY ACTIVE AT NIGHT.
- 5. BIRDS FACTS - All birds are oviparous. They incubate their eggs. This means they sit on the eggs to keep them warm while the baby grows inside. - All birds are vertebrates. - Birds can be CARNIVORES, HERBIVORES OR OMNIVORES. - Adult birds find food for their babies until they can find their own food. - Birds breathe with their LUNGS. - Birds have FEATHERS and WINGS, but not all birds can fly. Some can swim or run. Birds use their feathers for flying, keeping warm and attracting other birds. All feathers are WATERPROOF. - Birds have BEAKS. Birds of prey have HOOKED BEAKS for tearing meat. Birds that eat nuts and seeds have SHORT BEAKS. Birds that catch fish have LONGS, SHARP BEAKS. Birds that eat nectar from flowers have LONG, THIN BEAKS.. Penguins are aquatic birds. They mostly eat fish and other small sea animals. They can't fly, but they are very good swimmers. Ostriches are the largest birds in the world. Although they can't fly, they can run faster than any human. Eagles are carnivores. They are very good hunters and eat fish and other animals. Bald eagles make the largest nests in the world. Sparrows have SHORT BEAKS because they eat seeds. Pelicans have LONG, SHARP BEAKS which they use to catch lots of fish at once. Hummingbirds are one of the smallest birds. They have LONG, THIN BEAKS which they use to drink nectar from flowers.

THIS MEANS THEY SIT ON THE EGGS TO KEEP THEM WARM WHILE THE BABY GROWS INSIDE. NUTRITION CARNIVORES, HERBIVORES OR OMNIVORES. THEY HAVE DIFFERENT TYPES OF TEETH. CARNIVORES, HERBIVORES OR OMNIVORES. BABIES BABY MAMMALS DRINK THEIR MOTHER’S MILK UNTIL THEY CAN FIND THEIR OWN FOOD. ADULT BIRDS FIND FOOD FOR THEIR BABIES UNTIL THEY CAN FIND THEIR OWN FOOD. RESPIRATION THEY BREATHE WITH THEIR LUNGS. THEY BREATHE WITH THEIR LUNGS. CHARACTERISTICS MOST MAMMALS HAVE FUR OR HAIR TO KEEP THEM WARM. THEY HAVE FEATHERS AND WINGS, BUT NOT ALL BIRDS FLY. SOME CAN SWIM OR RUN. ALL FEATHERS ARE WATERPROOF. HOW THEY MOVE VS BEAKS -MOST MAMMALS HAVE 4 LEGS TO MOVE ON LAND. - SOME MAMMALS HAVE FLIPPERS TO MOVE IN WATER. - ONE MAMMAL HAS WINGS AND CAN FLY. BIRDS HAVE BEAKS. -BIRDS OF PREY HAVE HOOKED BEAKS FOR TEARING MEAT. -BIRDS THAT EAT NUTS AND SEEDS HAVE SHORT BEAKS. - BIRDS THAT CATCH FISH HAVE LONG, SHARP BEAKS. - BIRDS THAT EAT NECTAR FROM FLOWERS HAVE LONG, THINK BEAKS.
