Many bird species migrate south every autumn to escape the frigid winters of northern North America. As the snow melts and the plants begin to green in the spring, millions of birds flow back to their summer breeding grounds. While Common Terns and a few other species will breed here, other birds only make a short stopover on or around Ship Island before resuming their northward flight. We’ve had the pleasure of catching a glimpse of a few of these passersby.
Common Loons, Long-tailed Ducks, and Black Scoters overwinter on saltwater. Loons breed on inland wooded lakes during the summer, while the ducks nest in northern Canada. Some of these waterbirds around Ship may have spent the winter in Blue Hill Bay, but others are probably working their way up the coast from further south.
Shorebirds, such as Black-bellied Plovers, Least Sandpipers, and Short-billed Dowitchers spend the colder months along the southeastern and Mid-Atlantic coast. Foraging along the tideline of Ship Island, these birds can refuel for the rest of their trip to their Canadian breeding grounds.
Bird watchers throughout the country revel in the annual springtime flurry of songbirds, especially the colorful warblers. We on Ship are no different, chasing half a dozen warbler species around our small grove. Several Yellow Warblers and Common Yellowthroats will remain for the summer, but others are on their way to breeding grounds in mainland Maine. Magnolia, Blackpoll, and Chestnut-sided Warblers, along with a Northern Parula have all visited the island, gleaning small insects from the cherry trees.
No migration post would be complete without making mention of the Snowy Owl that visited the island before the summer crew arrived. Two volunteer island-sitters were lucky enough to spot this Arctic predator flying around the island before its northward departure. As wonderful a sight as it would have been, it is probably for the best that it continued its journey before the arrival of most of the owl-meal-sized terns.
Until next time!
