What reading level is Ornithology book?
To quickly assess the difficulty of the text, read a short excerpt:
B., 1859, No.
183; Review, 1864, 175.— B. B. & R., Hist. N. Am. B., 1, 1874, 196, pi! xi] figs. 7, 8.1— CooPEB, Orn. Cal., 82.— Coues, Key, 1872, 94; Check List, 1873, No. 67 ; B. N.W., 1874, 50.— Henshaw, 1875, 188.
Akhough not observed in summer, this bird was more or less com- mon in September in the thickets along the streams in the lower portion of the canons. It is not as yet definitely known whether this species breeds anywhere within the Western Eegion, or whether, on the other hand, th...e individuals which have been obtained at so many localities west of the Rocky Mountains were migrants from the Eastern Region, which, near the northern boundary of the United States, extends so much farther toward the Pacific coast. The same doubt exists in the case of Lanivireo solitarius.
It is well known, however, that towai'd our northern border the Rocky Mountains form much less of a barrier to the westward range of eastern species^ many of which, following the head-waters of the Yellowstone and other tributaries of the Missouri River, have but a short flight to reach the head-streams of the Columbia, and thus reach the Pacific coast in Oregon and Washington Territory, by passing down the valley of the latter stream.
