Where have all the birds gone? Many wildlife watchers have asked this question recently. Indeed, our feeders, after being in constant demand all summer, are now virtually empty of birds, save for an occasional goldfinch. As I recall, this is always a concern for feeder watchers at this time of year. There may be several reasons for this phenomenon. One thing to note is that there is plenty of natural food available. The woods are loaded with berries, nuts and insects, so the birds don’t need us as much.
Another factor is that juvenile birds have fledged and are now feeding themselves. Their parents no longer need to stuff several hungry mouths with food all day long. And an important factor is migration. Grackles and other blackbirds are now clustering into huge flocks, preparing for migration. We may see them at our feeders, but they quickly clean them out and move on. Hummingbirds filled up on sugar water and insects in the early part of September, and about mid-September they migrated south. Other birds have left too: warblers, catbirds, orioles, kestrels, cooper’s and broad-winged hawks. We are sorry to see them go; the woods are much quieter now. Some of the birds that we think of as year-round residents such as robins and jays, also move some distance south, and other robins and jays arrive here from Maine and Canada. We usually don’t notice that “our” robins are different robins than the ones we had this summer.
Most of our waterfowl have flown south, but some remain where there is open water. Some succumb to duck hunting season. There was an amusing quote about the hunting season printed in Bob Oliphant’s Westford Eagle column, “Museum Musings”, November 10, 2017. The quote is from the Westford Wardsman, November 10, 1917: “Hunters are busy firing at space and occasionally hit it–being more abundant than game. Keep right on, ladies and gentlemen, with the open season and we shall see where beautiful innocent bird life will be exterminated. But little is left now except grasshoppers, woodchucks and rats, about all else has either been killed off or frightened to death.”
One way to follow the progress of the migration season is to go to Cornell Lab of Ornithology’s website, BirdCast.info. On this fascinating site you can see the “BirdCast”, a three-day forecast of bird migration. Weather radar maps show birds migrating after sunset. They are updated every six hours. As I look at the map on October 2, it shows that Maine is experiencing a high level of migration intensity, and Massachusetts is showing a medium level. You can also watch a live migration map of your area in real time. Clicking on another map, one can see how “our” migrating birds navigated the major disruption of Hurricane Dorian that was moving up the coast in early September. Instead of migrating south along the coast as is typical, birds moved inland and caught tailwinds that speeded up their journey. We wish them safe travels.
Many thanks to all flora and fauna reporters for the month of October. Please send reports by November 26 to be printed in the next Westford Wildlife Watch. You can write to me at 7A Old Colony Drive, call me at 692-3907 or e-mail me at email@example.com
