I live in Mechanicsburg PA. Since enrolling in the Joy of Birdwatching course, I have notice a significant drop in Northern Mockingbird sightings. I would see them daily in my back yard as well as when riding my bike through the local parks and adjoining neighborhoods.
In fact, I haven’t seen any mockingbirds for at least two months. They are supposed to be year long residents here.
Anybody else notice this?
