NOTES: (Breeding Status: Territorial; Cover Density: Med, Thick)
Both the "cheeew" and the "tick" calls were made from high treetops by three birds approaching their roosting hole in a dead tree in the lake. With each "cheeew" call, the bird bowed the head vehemently down, the bill nearly hitting the 45¡ trunk.
