When birds can't find food in their normal seasonal habitat, they fly farther afield to search. This is known as an irruption. And while it's tough on the birds, it does make for more interesting birding for those trying to complete a life list.
This season, birders are seeing more redpolls, grosbeaks and crossbills in the region than they normally would at this time of year.
Bird Diva Bridget Butler talks about the reasons for this season's irruption and the best places to see these birds.
