The Common Redpoll is one of the more colorful birds you'll see at your backyard feeder this winter.

The finch spends most of the year in the cold Arctic regions, but when food gets a little scarce, they travel south. But not that far south.

One of the most southerly areas on the National Audubon migration map is Montana. And, yes, the Bitterroot Valley already has some Redpolls showing up.

Cold doesn't seem to bother them. It's the food supply that drives them out of their northerly domain.

So, keep the seeds well stocked in your feeders and you might just catch a glimpse of this finch.
