White-winged Crossbill Feeding Technique

Have you perused or subscribed to The Cornell Lab of Ornithology's YouTube channel? It offers an incredible selection of videos related to birds and birding.

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.
