For instance, check out this video that illustrates the feeding technique used by White-winged Crossbills to extract seeds from white spruce trees. The crossbill item is one of a handful in the Lab's "How Nature Works" videos.
You can learn more about White-winged Crossbills, including their song and call, by visiting Cornell's All About Birds website. It's quite a treasure trove.
