Alpaca fiber nesting material offers birds a premium, natural alternative for nest construction. This one-ounce bundle of locally-sourced alpaca fiber provides exceptional insulation for developing chicks during cool spring weather. The fiber's hollow structure remains lightweight while delivering superior warmth retention. Unlike synthetic materials, alpaca fiber naturally resists moisture absorption and fluffs back to full loft after rain exposure. Simply place the fiber in a mesh produce bag or wire suet holder and hang from a tree branch. Chickadees, titmice, and goldfinches particularly favor this sustainable nesting option for its superior thermal properties and workability.
