On Saturday, October 4, 22 birders awoke before sunrise, loaded into vans, and began our journey from Northern Virginia to Cape May, NJ, our eyes set on this faraway destination perfectly aligned with the Atlantic Flyway, one of the four “avian superhighways” in North America.
Spring migration is about to bring millions of birds north along the Atlantic Flyway, a welcome sight for Virginia bird-lovers emerging from a season of persistent cold and stubborn snowbanks. With these birds, concern is also returning about a bird flu outbreak that has been active in the U.S. since early 2022.
Now is the time to clean and fill the feeders to help birds make a living when other food sources are scarce. It’s also time to think about providing next year’s winter bird food by planting more native plants, including native grasses, wildflowers, and woody plants, such as shrubs, vines and trees, that provide sustenance all winter long.
Fall-fruiting native shrubs and trees not only provide nutritious, fatty berries for birds, but also display beautiful fall color. That’s not for our benefit: what’s called foliar fruit flagging is the way the plants signal to birds that fruits are ripe and ready for plucking—just in time for migration.
The July 2023 Statement from the international Scientific Task Force on Avian Influenza and Wild Birds includes some alarming information about the effect of the current avian influenza or “bird flu,” H5N1, but it also includes some helpful recommendations on steps we can take to keep from exacerbating the spread of this deadly disease.
