Abstract: Seven nuthatches of four pairs studied at their nests inspected models of snakes placed nearby without otherwise reacting to them initially. Six of these seven then flew away, gave alarm calls, and/or performed threat displays to the snake model. Threat displays included Tail-Fan-Back-Ruffle, Wing Spread and/or Sway.
