A recent study by two College of Charleston grad students working with the Nature Conservancy has confirmed that the insect-eating birds, which nest in the bottoms, not only depend on the fields for the bugs they eat, but will go for miles from field to field looking for mass hatches of particular bugs, what are called insect eruptions.

The study by Tera Baird and Chris Simmons will help conservationists make recommendations to those landowners, said Maria Whitehead of the Nature Conservancy, an adjunct professor at the college who worked with Baird and Simmons.
