On the 8th of August, 1832, Mr. Audubon, in company with Mr. Nuttall, obtained the specimen of this species in Brookline, Mass., from which his drawing was made. In the course of his journey farther east, Audubon found it in Maine, on the Magdeleine Islands, and on the coast of Labrador. He afterwards met with it in Texas.
Mr. Boardman reports the Olive-sided Flycatcher as having of late years been very abundant during the summer in the dead woods about the lakes west of Calais, where formerly they were quite uncommon. Mr. Verrill mentions it as a summer visitant in Oxford County, in the western part of
the State, but not very common, and as undoubtedly breeding there. It was never observed there before the 20th of May. It is said to be more abundant at Lake Umbagog.
In Western Massachusetts Mr. Allen regards this bird as a not very rare summer visitant. It arrives about May 12, breeds in high open woods, and is seldom seen at any distance from them. It leaves about the middle of September.
Mr. William Brewster, who resides in Cambridge, in the neighborhood in which this species was first observed by Mr. Nuttall, informs me that these birds still continue to be found in that locality. He has himself met with five or six of their nests, all of which were placed near the extremity of some long horizontal branch, usually that of a pitch-pine, but on one occasion in that of an apple-tree. The eggs were laid about the 15th of June, in only one instance earlier. The females were very restless, and left their nest long before he had reached it, and, sitting on some dead branch continually uttered, in a complaining tone, notes resembling the syllables pill-pill-pill, occasionally varying to pu-pu-pu. The males were fierce and quarrelsome, and attacked indiscriminately everything that came near their domain, sometimes seeming even to fall out with their mates, fighting savagely with them for several seconds. When incubation was at all far advanced, the birds evinced considerable courage, darting down to within a few inches of his head, if he approached their nest, at the same time loudly snapping their bills.
A nest of this Flycatcher was found in Lynn, Mass., by Mr. George O. Welch, in June, 1858. It was built on the top of a dead cedar, and contained three eggs. It was a flat, shallow structure, five inches in its external diameter, and with a very imperfectly defined cavity. The greatest depth was less than half an inch. It was coarsely and loosely built of strips of the bark and fine twigs of the red cedar, roots, mosses, dry grasses, etc. The nest was so shallow, that, in climbing to it, two of the eggs were rolled out and broken.
Mr. Charles S. Paine has found this bird breeding in Randolph, Vt. On one occasion he found its nest on the top of a tall hemlock-tree, but was not able to get to it.
In Philadelphia, Mr. Trumbull found this species very rare. It passed north early in May, and south in September. Near Hamilton, Canada, it is very rare, none having been seen; and two specimens obtained near Toronto are all that Mr. McIlwraith is aware of having been taken in Canada West.
Dr. Hoy informs me that this species used to be quite common near Racine, frequenting the edges of thick woods, where they nested. They have now become quite scarce. Some years since, he found one of their nests, just abandoned by the young birds, which their parents were engaged in feeding. It was on the horizontal branch of a maple, and was composed wholly of usneæ.
In Washington Territory this bird appears to be somewhat more common than in other portions of the United States. Dr. Suckley obtained a specimen at Fort Steilacoom, July 10, 1856. It was not very abundant about Puget Sound, and showed a preference for shady thickets and dense foliage, where it was not easily shot. Dr. Cooper speaks of it as very common, arriving early in May and frequenting the borders of woods, where, stationed on the tops of tall dead trees, it repeats a loud and melancholy cry throughout the day, during the whole of summer. It frequents small pine groves along the coast, and also in the interior, and remains until late in September.
