More White-breasted Nuthatch images, this time from our recent visit to the University of Minnesota Landscape Arboretum. These birds are common across much of the United States, southern Canada, and the Mexican highlands. Nuthatches often feed upside down on tree trunks, probing the bark and other crevices for insects and cached seeds. Nuthatches pound seeds with their bills to open them. Grubb and Pravosudov. (2008) surmise that this behavior gives rise to the nuthatch name.
