Mimicry

• Mimicry is when a weaker animal looks like a stronger animal’s characteristics to warn off predators. Some animals who use mimicry include snakes, beetles, flies, caterpillars, bees, sea slugs, and countless others. Can you tell which snake is the mimic? The scarlet king snake is mimicking the venomous coral snake.

Camouflage

Camouflage is a method of hiding one’s self by making itself appear as part of its natural surroundings. Many animals use this to hide themselves from predators, and as a way of hunting. Some animals naturally blend in to their environment, and some can change what they look like to blend in to their surroundings.

Hunters wear Camo to camouflage themselves in the woods

Migration• Migration is the process of

changing location from time to time, especially by moving from season to season from one region to another. Animals migrate due to climate changes, food supply, and for purposes of reproduction. Migration usually involves moving from one area to another then back again. Some species such as the Pacific Salmon are born in streams, travel to the ocean, and then return to the stream where they were born to reproduce before dying. Even some microorganisms migrate in lakes. Migration is involved with a wide range of animal types.

Hibernation• Hibernation is a time where

animals sleep through cold weather seasons. This is a sleep like no other. Loud noises can not wake the animal, neither would touching it. Animals that hibernate include badgers, bats, squirrels, hamsters, hedgehogs, prairie dogs, raccoons, skunks, and bears. In the fall, the hibernating animals eat much more than normal to gain fat because when animals hibernate, their bodies live off the fat. Hibernating animals create Winter nests, dens, or burrows to hold in heat during the hibernating season.

Beak Types• Beak Types vary in size, shape, and

color. The uses of these beaks vary as well.

• Strong hooked beaks are common on raptors (predator birds, who’s beaks are usually curved and strong for an aggressive style of hunting). These beaks are great for eating fish. An eagle is an example of a raptor. A heron is a bird commonly found near water and has a dagger-like beak for impaling fish and frogs. Humming birds have long skinny beaks for sucking out the nectar in flowers. Birds like cardinals have cone-shaped beaks used for cracking seeds and nuts. Birds like snipes have very long beaks to search for food in water or mud. Woodpeckers’ beaks resemble a chisel, which helps them find bugs inside of trees. Birds like sapsuckers have beaks that work like drills to eat sap and bugs inside of trees.
