Update (December 2010) Winter Finches-- "Winter finches," as they are known to the birding community, are a group of birds that periodically irrupt southward when seed crops crash in the North. During "invasion years" flocks can be found well south of typical wintering areas, and backyard feeders can become inundated with hungry finches. In our latest update, we've focused on five species that are typically involved in these winter finch irruptions: Purple Finch, Red Crossbill, Pine Siskin, Common Redpoll and Hoary Redpoll. These updated accounts include newly revised photo, audio and video galleries, as well as new identification content (located in the Distinguishing Characteristics article). With the cold of winter on its way, read through the new accounts and prepare yourself to identify a suite of potentially new backyard birds.
