With Josiah Clark Bird migration is like a tide that washes over us twice per year, bringing both abundance and diversity. Unlike the ephemeral movements of spring when the birds are racing to be the first to set up territories in newly-leafed and thawed habitats, in fall, with the breeding season behind them, birds are content to move south more slowly. We will visit several habitats and study numerous bird guilds, discussing when, why and where each group may be coming from and going to. Josiah will also teach us about general weather patterns and how they affect bird migration in our area. We will also study plumages of immature sparrows and other breeding songbirds and listen for the late summer and fall begging calls that can confuse even experienced birders. We will be looking to find and acquaint ourselves with the first passing fall migrants as they come into basic plumage.
