Although it is now extinct, the Carolina parakeet was last seen in Florida in 1920. Back then, large areas of habitat were logged and converted to agricultural fields. Honeybees evicted the parakeets from hollow trees where they nested. Many parakeets were shot for food and their feathers. In addition, farmers shot the parakeets to keep them from eating their seeds. What can you conclude from these observations about why the Carolina parakeet became extinct?

• Extinction may be the result of several factors.

• Extinction is always the result of human activity.

• Extinction occurs when an organism adapts to changes in its environment.

• Extinction can be reversed if conservation measures are immediately put in place.
