Every spring and fall a natural wonder of wildlife migration takes place quietly overhead in the dark, unseen by most people. Millions of small colorful songbirds and interesting birds of all shapes and sizes wing their way between Canada or the northern United States and countries further south, from Mexico through the Caribbean and Central America. Some fly all the way to the tip of South America. At daybreak these birds passing overhead will land and find themselves in our neighborhoods and preserves. They are hungry and exhausted, and are looking for trees, shrubs and plants to provide them with insects and berries to refuel, as well as shelter for resting before they resume their long-distance journeys.
