Great Egret

Great Egrets Dispersing

great egret flyingAlthough Great Egrets breed sporadically as far north as Vermont, seeing one in northern New England is always noteworthy. The likelihood of a sighting increases as summer progresses, due in large part to the phenomenon of post-breeding dispersal. After young Great Egrets have fledged, individuals wander well outside their typical breeding range, as far north as southern Canada. The northward dispersal of juvenile birds peaks in August and September. Most Great Egrets migrate in the fall, from September through December.The extent of their migration is influenced by annual fluctuations in temperature. When winters are mild, individuals may remain as far north along the Atlantic Coast as Massachusetts.

Great Egrets Migrating

4-18-14 great egret2  055After overwintering in Central America and southern U.S., Great Egrets head as far north as the New England coast and Vermont’s Champlain Valley to breed. The peak of their spring migration occurs in April so now is a good time to look for them in wetlands where they stop to rest and refuel en route. Great Egrets eat mainly fish, but also crustaceans (see crayfish in insert), amphibians, reptiles, birds and small mammals.
