Note: Jeanne Strahen, who’s conducting the wildlife inventory of the park, will lead a FREE bird walk THIS Saturday, June 3. Meet on the BU Bridge, facing the park, at 7:30am. Bring your binoculars! (Rain date: Sunday, June 4.)
Each spring, warblers wintering in Mexico and Central America catch favorable air currents and begin their migration up through the Midwest, then head east to New England and Canada, where they breed in the summer months. The migration peaks in the first two weeks of May, when groups of warblers arrive at Magazine Beach after traveling as much as 200 miles in the previous evening. They stay a day or two to rest and feed on insects. Depending on the weather, they will be joined or replaced by a new group of warblers every day or two. Each group brings new species, most of whom will head north. I’ve identified sixteen species at Magazine Beach since the beginning of May. Look for them in the tall trees around the Magazine Street entrance.
