Purple Finches Irrupting

Every year a Winter Finch Forecast ( ) is published which predicts which finches in the northern boreal forests might be extending their range south due to a poor food supply farther north. These larger-than-normal movements of birds are referred to as irruptions, and they happen every year, to varying degrees with varying species. 

This year’s Winter Finch Forecast predicted that Purple Finches would irrupt southward, following the large spruce budworm outbreak (producing short-term population increases) and poor mast crop in much of the eastern boreal forest.  The past few days have proven the forecast right and signaled the start to a large-scale irruption event. Once Black Bears have gone into hibernation and your feeders are up, keep an eye out for ever-increasing numbers of Purple Finches (as well as irrupting Evening Grosbeaks).
