The next group of birds that will be moving into the area on their southbound migration are the ducks. There are already scattered reports of ducks across the state, but numbers should really increase over the next few weeks. Below are the eBird frequency graphs for the ducks, split into dabbling, diving and sea ducks. These graphs show the percentage of checklists reporting that species in Pennsylvania. Dabbling ducks should really be arriving enmasse in the next week or so while diving ducks will really start to increase once November comes. Long-tailed Ducks, Canvasbacks and the large scoters will then follow in the middle of November.
