Every fall serious birders, both field birders and backyard feeder watchers, wonder what the coming winter will bring in the way of migratory and irruptive northern finches. The movements of northern finches such as pine siskins, purple finches, common redpolls, and crossbills can vary widely and wildly from year to year. For example, in some years pine siskins may dominate feeders even as far south as the Carolinas. In other years they may be completely absent.
Movements tend to be based on the availability of food produced by northern conifers. The better the yield of seeds the more likely the birds are to stay to the north. Poor yield or crop failure results in birds moving around more. And it really isn't limited to just finches. Other species like red-breasted nuthatches, waxwings, and blue jays are affected too.
Ron Pittaway released his Winter Finch Forecast for 2014-15 recently. Though predictions are generally for the northern and northeastern United States, some insight can be gained into what species we might expect to encounter here in the piedmont of the Carolinas.
