A.B. Hamilton 1965 Polysticta stelleri Jun. 26 low area at the N end of the Britton Area. They always were observed in pairs and one pair claimed ownership at least transiently of a small puddle. Sometimes there was violent interaction between pairs. One pair would chase the other with all four birds throwing their head and necks back over their necks at about the rate of one / second. The birds looked especially ludicrous waddling as fast as they could while continually throwing their head back. When one pair got close to another they would lower their head and necks till about parallel to the ground and would rush at the other. If the birds were in water the chase would become quite violent and water would be splashed up to about two feet in the air. As this pursuit occurred a "gwarah" sound was heard but I couldn't tell which birds were making it. The pursuit always ended when the intruder retreated. June 27 A total of eighteen were observed in suitable places in the Tundra. June 28 Eight present in Britton and with Areas. June 29 Ten were observed. June 30 Twelve were observed. A female has been consistently seen near trapline II and will probably try to bait them. July 1 Six were observed. July 2 Eight were seen. July 3 Five was seen. A long trail observed near lake 100. July 4 Six seen. Bird still present near lake 100.
