Abstract: The throat was white, not definitely outlined, but gradually shading to brilliant yellow underparts.The two birds were identical.Williams and I observed the birds for at least a half hour under ideal light conditions, close at hand.We concluded that both birds were the Tropical Kingbird (Tyrannzrs melancholicus).Recent casual occurrences of this species north of its summer range have been summarized by Cogswell (Condor, 54, 1952 :1' 17).All recent Californian records have been made in October.-KENLEGG, Point Lobos Reserve, Carmel, California, January 6, 1953.Northern Record of Nestling of Red-necked Grebe.-Apair of Red-necked Grebes (Colymbus grisegena holbiillii) was found by David Walsh on July 18, 1949, nesting on an oxbow of the Itkillik River near its junction with the Colville River, Arctic Alaska.The nest contained three eggs.Floating vegetation was piled to a 5-inch high crown and the nest was located at the edge of the shoreline vegetation about thirty feet from shore.The birds were extremely wary and only after three cautious visits to the nest were both adults observed and identified at close range.The nesting bird would slink from the nest, cover the eggs and submerge in the water with the least provocation.This was our only sight record of this species in the course of six weeks spent on the Colville River.The author has been unable to find previous records of this grebe nesting this far north in Alaska.-
