16" Mesh Nyjer Sock (SE639)

A jumbo 16 inch durable nylon mesh thistle sock for goldfinch feeders, offering maximum feeding surface area for flocks of American goldfinches, pine siskins, and common redpolls at Ontario backyard bird feeding stations. Mesh construction lets finches cling naturally and access Nyjer seed from any angle, mimicking the way they feed on wild thistle in the field. Fill with fresh Nyjer seed for best results and replace when mesh begins to break down.
