White-breasted Nuthatches are small, stocky, black-capped songbirds, most often seen as they actively forage up and down the trunks of large trees. This species readily visits backyard feeders, and typically flies off with a single seed before using its wedge-shaped bill to hammer open the shell on a branch.
Nuthatches are wonderful, perky birds that can be entertaining backyard visitors, but it can be challenging to attract nuthatches. How can you encourage these small climbing birds to visit your feeders or take up residence in your bird houses? Here.
