Dr. Cooper, in his Birds of Washington Territory, speaks of this Wren as common about Puget Sound, where it appeared to be much less familiar than our common Wren, though its habits and song seemed to be very similar. It there frequented chiefly the vicinity of woods and piles of logs, neither seeking nor dwelling in the vicinity of houses. It arrives there about the 20th of April. As observed about Vancouver in 1853, its song appeared to Dr. Cooper different from that of the _T. ædon_. He found one of their nests built in a horse’s skull that had been stuck upon a fence. Dr. Suckley, who observed these birds about Fort Steilacoom, describes their voice as harsh and unmusical. Dr. Cooper has since observed them in California, and in the winter, in the Colorado Valley, where they roosted at night under the eaves of the garrison buildings. They make their appearance at San Francisco as early as March 16, and nest at San Diego in April. He has found their nests in hollow trees at various heights, from five to forty feet, all composed of a floor and barricade of long dry twigs, grass, and bark, loosely placed, but so interwoven as to leave only just space for the birds to squeeze in over them. They are warmly lined with a large quantity of feathers. Their eggs he gives as from five to nine in number. The late Mr. Hepburn has furnished more full and exact information in regard to this species. We give it in his own words. “The _T. parkmanni_ is the common wren of Vancouver Island, far more so than of California, where I have found the Bewick’s Wren (_T. bewickii_) much more numerous. Parkman’s Wren builds its nest in hollow trees in Vancouver Island, about the middle of May, forming it of small sticks laid at the bottom of the hole, neatly and comfortably lining it on the inside with feathers that arch over the eggs. It will also readily avail itself of any similar and equally convenient cavity. I have known these birds to build under the roof of a frame house, entering by a hole between the topmost board and the shingles; also in a hole in a gate-post, through which gate people were continually passing; and also over a doorway, getting in by a loose board, in a place where the nest could be reached by the hand. In 1852 I put a cigar-box, with a hole cut in one end, between the forks of a tree in a garden at Victoria. A pair of Wrens speedily took possession of it and formed their nest therein, laying seven eggs, the first on the 18th of May. The eggs of this Wren are white, thickly freckled with pink spots, so much so in some specimens as to give a general pink appearance to the egg itself, but forming a zone of a darker hue near the larger end. They are .81 of an inch in length by .50 in width.”
