Fall Migration Summary

Spring migration is often characterized by large masses of brilliantly colored birds passing through Magee Marsh within a very brief time period. Fall migration does not give us the brightly colored hues that adorned many of our feathered friends in the spring, but it does give us more time to enjoy their passage to their southern wintering grounds.

Fall migrations are much more drawn out, and some sort of migration can be seen from as early as July to as late as early January. By knowing the general sequence of migration and the favorable weather conditions, we can enjoy the many sights and sounds of these fall flights.

Weather Watch

Look for northerly winds and Canadian cold fronts. These cold air masses bring lower temperatures, winds coming in the direction of the migrating birds, usually clear skies.

July

Shorebirds - Shorebirds begin returning from the north. Lesser and greater yellowlegs, semi-palmated sandpiper, short-billed dowitchers.

Passerines - Eastern phoebe, yellow warblers, Baltimore orioles begin staging in the marsh region. Martins and swallows begin staging.

August

Waterfowl - Mallards migrate to marshes to molt. Blue-winged teal arrive.

Shorebirds - Migration continues (peaks late August-early September). Yellowlegs, pectoral and semi-palmated sandpipers, and semi-Palmated plovers.

Passerines - Flycatchers, yellow and prothonotary warblers head south. Bobolinks staging and blackbirds begin roosting in the marshes. Martins and swallow migration peaks.

Waterfowl - Blue-winged teal migration peaks. Green-winged teal arrive.

Waterbirds - Rails peak early in the month. Great egrets communally roost in the marshes, and gull and tern migration peaks.

Raptors - Bald eagle staging at its peak in the marshes. Other raptors peak but are sporadic in this area.
