A crew transfer occurred on Oct 25th ushering in a shift from the early and mid season migration to the late season migration. During fall migration, the early migrants include the bulk of the shorebirds, flycatchers, and warblers which pass through mostly during late August and September. During October, these species begin tapering off rapidly while the sparrows and kinglets rapidly increase. This overlap of early and late migrants creates the greatest avian diversity on the island in early October when we hold the Farallonathon. During November, the late period, gulls, sparrows, and thrushes typically dominate.
