Birds usually fly relatively low. Most of the year, they stay under 500 feet. During migration, though, birds gain altitude, and many species fly at 2,000 to 5,000 feet or higher, using prevailing winds to assist them. A bird may begin migration at about 5,000 feet and slowly climb to 20…

Have you ever wondered how some migrating birds return to the same location, year after year? Do they learn from their parents, or do they just know how to migrate? Some birds (like this Bar-tailed Godwit) have an innate homing ability, while others follow their parents. The Bar-tailed…

Many years ago, when rivers began flowing from the mountains to the sea, the animals couldn't agree on their course. Raven wanted the rivers to turn and wind, so that as he flew up and down them, he would have different views at every bend. Mink disagreed. The loud and raucous Raven…

In spring, the Black-capped Chickadee adds a new vocalization to its repertoire. When breeding season begins, the tiny brains of Black-capped Chickadees and other songbirds enlarge to enable the birds to create more sounds. After the breeding season is over and the birds no longer need…
