| Behavioral adaptations
are inherited behaviors that help animals survive. Some behavioral adaptations are called instincts. They affect how an animal behaves around other animals of the same species or different species. Lemmings are small rodents that have an instinct to migrate if their population in an area gets too large. Some animals, like musk oxen, have an instinct to form a circle around their young when predators threaten them. |
|
| Not all behaviors of an animal are due
to behavioral adaptations. Some behaviors are learned. For example, lion parents teach their offspring how to hunt. A lion cub stays with its mother for 2 or 3 years until it can hunt on its own. |
| The
way that a hummingbird makes a nest is a behavioral adaptation. |
| Legs that can tuck close to the body make it easier for the hummingbird to fly. This is a structural adaptation. |

Expository During your
life, you have learned some behaviors that have helped you survive. In your science journal, write a survival guide using information that you have learned about safety around the house. |
