Dock: Tall red-brown spires

This distinctive prairie wildflower with tall red-brown waving spikes is classified as a weed by the Canadian federal government and several US states. Parts of it are said to be toxic to poultry (Royer & Dickison) but redwinged blackbirds apparently have no problems living in or near it.
