Birds live in diverse habitats: deserts, mountains, forests, tundras, near the bodies of water, etc. A lot of birds never leave their living places, the others migrate to warmer countries when the weather changes. Migrations may be tens of thousands of kilometers long. Most birds can fly by means of feathered wings.
Life Expectancy of Birds. Live long and prosper. For small songbirds, that might be seven years! A songbird in the wild has less than a 50% chance of surviving more than two years. However, if a young bird can survive accidents, disease, predation, migration, and winter starvation, it may live a surprisingly long time. As a general rule, larger birds tend to live longer. It also helps to be at the top of the food chain. A Laysan Albatross has survived 42 years and 5 months in the wild.
