Beak Types

Hibernation/Estivation

2. Mimicry: When an organism looks like or copies something that other organisms either want to avoid or are attracted to
Aggressive mimicry: when animals copy something to lure prey
Batesian mimicry: when a harmless organism looks like a harmful one
Example: milk snake looks like a coral snake
Mullerian mimicry: when harmful organisms look alike
Example: yellow with black coloration of wasps, African honeybees, and yellowjackets
Camouflage: when an animal can blend in with its environment
Draw & color 2 examples (grasshoppers, stick insects, etc.)
Beak Type: different beak types allow different species to have different diets
Draw & color 3 different beak types & explain what they are

4. Migration: the movement of animals from one region or climate to another for a specific period of time to find warmer climates with more plentiful food supplies
Draw & color 3 examples of animals that hibernate
Birds, bats, whales, fish, elk, butterflies
Hibernation: during the winter, animals go through a resting state when their entire metabolism slows down including digestion, respiration, and heart rate
Estivation: a resting state similar to hibernation that animals use in hot weather; it can be daily or longer
Draw & color 2 examples of animals that hibernate
Examples: bears, ground squirrels, snakes, rabbits
Draw & color 2 examples of animals that estivate
Examples: snakes, lizards, iguanas, desert tortoise, salamanders, frogs
