The peregrine falcon has a sad and difficult history in the Eastern United States, with the use of DDT on crops causing the falcon eggs to be thin-shelled and to break under the weight of parent birds during incubation. By 1966 it seemed that peregrine falcons in Massachusetts were a thing of the past. When DDT was banned in 1972 (30 years ago), efforts were made to reestablish the falcon, and now there are more than a dozen nesting pairs in Massachusetts.
The UMass Du Bois Library is home to one of these nesting pairs, and they have laid eggs. You can watch the falcons, and hopefully the chicks in upcoming weeks, from the webcam on the library roof.
Enjoy your view of the birds!
