Nesting Material

You can help your birds build nests by keeping natural materials in your yard or by offering them suitable provided items.

Natural

  • Structural materials (outer nest layer). These items give the nest strength and shape.
  • Small twigs and sticks.
  • Dead leaves, dry grass or straw (must be untreated—no pesticides or fertilizers).
  • Pine needles, bark strips.

Soft lining materials (inner nest layer). These provide warmth and insulation for eggs and nestlings.

  • Feathers.
  • Plant fluff or down (e.g., cattail fluff, cottonwood down).
  • Moss, lichen, rootlets or fine plant fibers.

To offer nesting material safely place materials loosely (never tied or bundled).

  • Use: open trays, clean suet cages.
  • Place small piles in shrubs or under trees.
  • Keep materials dry and mold‑free. Refresh after rain if needed.

Materials you should never provide. These items are repeatedly linked to injuries, nest failure, and chick deaths.

  • Dryer lint - Contains chemical residues, falls apart when wet, can suffocate or chill nestlings.
  • Yarn, string, twine, thread.
  • Human hair, plastic strips, tinsel, cellophane long pet fur, any pet fur treated with flea medication.
  • Fabric scraps or synthetic fibers.
