Follow That Flock!
You don’t have to be a birder or ornithologist (a.k.a. a bird scientist) to think this graphic is fascinating. This map shows where American Pipits, a small, sparrow-like bird, can be found throughout the year. The American Pipit likes the open country. During its breeding season, the little birds set up camp in high tundra latitudes, such as the Arctic, and high alpine altitudes, such as the Rocky Mountains. This is why you may notice they nearly disappear from the map in the spring and summer.
