Jan., tuo?l THE CONDOR 7 owner, but she had wisely disappeared. W'e collectors know how to wait, as well as to labor; and so I ensconsed myself in a convenient place and waited. Presently the owner appeared, uttering a somewhat harsh but subdued "quit," flipped her tail nervously to inform me that. she was a flycatcher, and dodged behind an adjacent clump. However, at length I captured her (my Audubo- nian spirit prevents my saying that I shot her); nest and eggs were soon packed in my basket, and another find- ing recorded in my note-book. This nest stands three inches in height, the exterior diameters averaging two and three-fourths inches. The rim of the cavity averages one and thirteen- sixteenths in diameter, the depth being one and three-fourths inches. The structure is made of gray vegetable fibers, such as soft strippings from weed-stems, with which are interwoven cottony vegetable materials and bits of gossamer. The lining is delicate grassy fibers, used sparingly, and small, downy feathers which project from the well. The illustration shows the position of the nest better than we can describe it. It may not be amiss to say here that while my business in the Flathead region in July and August was to assist in Liological work for the Montana State University, my purpose there in June was to pick up a few sets of eggs for my own little collection. You will therefore understand that when I became awake to what a treasure a common maple clump xnight contain, few of them escaped my earnest glance. The first nest of E. wri?htii was taken on June xS; it was not until the x8th that I chanced upon my second nest. The locality was a high ridge east of the lake near our camp. I had wan- dered aimlessly onward and upward, allured by the clumps of maple that dotted the hillsides and intermediate valley. Clump after clump was exam- ined; but at length I spied a nest that seemed promising. It was ten feet from the ground, in an upright crotch near the top of the clump. To reach it safely I had to strap together a bundle of the light sprouts. This nest contained five eggs, somewhat advanced in incuba- tion. In structure and appearance, it is a counterpart of the one first described. The collector can give little excuse for taking a series of eggs and nests of ?mpidonax wr?htii, upon the ground of variation, as the eggs are practically all alike except deviations in size, and the nests look much alike exteriorly. I just wanted more eggs, I suppose, (you understand the feeling, Mr. Editor), so I kept scanning the maple clumps, and on June 20 I found my third nest. It was on the same ridge where I .had taken the second one. This third nest was only four feet from the ground, situated as usual in an upright crotch of maple sprout. It stands two and one- half inches high, the interior dimensions being the same as those given for the first nest. There were three fresh eggs in this nest. What, another nest? Yes, back in the nmrgin of the swamp-woods. Four days of further search netted nothing in the way of flycatcher's eggs, though I managed to get fair returns for the time in other ways: buton June 25 I chanced upon my last nest of Empidonax wrightii, which contained four eggs in which incubation had well begun. It was eight feet from the ground, in a crotch in an oblique stem of a maple sprout. The nest stands three inches high, the cavity averaging two and one- eighth inches in diameter at the rim. This nest is somewhat different from the others in its large and shallow cavity, and in the amount of felted material used in the inner wall. All the nests of this flycatcher have a con- siderable amount of loose material at the bottom, as an exterior foundation. Theodore J. Hoover is spending the Christ- mas vacation with Dr. J.P.
