Helpful Tips

  • Place the platform in the forest interior, preferably near a standing dead tree that can be used for perching.
  • Readily accepts artificial platforms even when natural sites are available.
  • Artificial platforms bring better nest success and allow the birds to nest in habitat that has no natural sites.
  • Construction tips: Use a plant stand with a 12 inch opening to hold the cone during construction. Build a raft-like base at the bottom of the nest cone and secure the base to the sides of the cone with landscaping wire. Create vertical stick spokes, (visualize a bike wheel) to use for attaching horizontal sticks.  Work your way from the bottom to the top, securing sticks in 6 inch segments with landscaping wire. Add loops to the outside of the cone to aid in installation.
