T. Richardson 1937 Eastern Kingbird (Tyrannus tyrannus) June 6, 1937 - Phasel, Warner Valley, Oregon - Three of these birds were collected in the open meadow-willow thicket association-the meadow, though cultivated (hay) in part, being quite unassociated with civilization. A pair was first seen and one bird collected. This proved to be the 8- will tests hypertrophied. A nest in process of construction was found. The mate, though rather wary, was seen to bring nesting material shortly after the first bird was collected. The nest is in a dead, small, willow, about 10' high. June 7, 1937 - Phasel, Warner Valley, Oregon - The mate, ♀, of the above 3 was collected while returning to the nest- probably still actively constructing it. It seems significant that the nest building instinct has been powerful enough in the ♀ to hold away after the absence of the ♂. Yesterday! the ♀ did not approach me at all when the ♂ was shot- this in contrast to ♀'s of other species who may be actually alarmed by the dead ♂ and boldly approach it (cf. Brewer Blackbird). The time in the nesting cycle is probably influential in this problem.
