© A. Weinberg What if you are having a snowball fight? You probably run away from the person throwing at you, and maybe even try to sneak up on that person and throw some snowballs! © A. Weinberg Now let’s learn about Behavioral Adaptations… Behavioral Adaptations allow animals to respond to life needs. © A. Weinberg Behavioral Adaptations are behaviors that allow animals to find food, protect itself from predators, and survive in its environment. Remember that Physical Adaptations are body structures. Each organism has unique methods of adapting to its environment by means of different actions. © A. Weinberg We can divide Behavioral Adaptations into two groups: Instinctive These behaviors happen naturally & don’t have to be learned. © A. Weinberg Learned These behaviors must be taught. Instinctive behaviors Methods of gathering & storing food Finding shelter © A. Weinberg = happen naturally & don’t need to be learned Defending oneself Raising young Hibernating Migrating Learned behaviors © A. Weinberg = Obtained by interacting with the environment and cannot be passed on to the next generation except by teaching. Types of Behavioral Adaptations • • • • • • • • • • Migration Hibernation Living in Packs Spinning Webs Stalking Prey Staying still Fleeing predators Shooting spray Sounding scary Looking scary © A. Weinberg QuickTime™ and a decompressor are needed to see this picture. © A. Weinberg What is hibernation? • This is a very special kind of deep sleep • It is brought on by short day lengths, cold temperatures and food shortages © A. Weinberg QuickTime™ and a decompressor are needed to see this picture. Why do animals hibernate? • It is a survival strategy • Dropping into a deep hibernation means animals are using less energy • Food is scarce • Animals miss the cold seasons © A. Weinberg What are the dangers of hibernation? • The animal is defenceless, which means it maybe attacked by predators and eaten! © A. Weinberg How do animals prepare for hibernation? • They try to put on as much fat as possible because they wont be eating much during the winter • This is called brown fat, which is found across the back and shoulders, close to an animal’s organs • Brown fat works hard to deliver quick energy to an animal coming out of hibernation © A. Weinberg Light Sleepers • Some animals are not true hibernators • They are easily awakened during their winter slumbers • These animals breathe a little more slowly and lower their body temperature a few degrees • The wake up to forage between winter snows • Bears, skunks, raccoons © A. Weinberg What is Migration? © A. Weinberg What is migration? Migration: • Seasonal back and forth journeys between two places. © A. Weinberg Which animals migrate? • • • • • • Mammals Birds Amphibians Reptiles Fish Insects © A. Weinberg Why do animals migrate? – – – – – Animals migrate to find food or weather advantageous to their survival. Animals migrate in a set pattern. Some travel short distances (birds, bats, whales). Some travel long distances (songbirds, shorebirds, waterfowl, hawks, some bats and whales. Some animals move up and down mountain slopes because of snow depth and food conditions (deer, elk, Mountain Goats, Spotted Owls, some songbirds) © A. Weinberg Bird Migration Over 5 billion land birds migrate between Europe and Asia to Africa 75% of 650 bird species that nest in N. America migrate © A. Weinberg Dangers of Migration • Predation – Land and water • Human destruction of migration points because of over population. © A. Weinberg
