Excerpt from The Philosophical Magazine and Journal, Vol. 66: Comprehending the Various Branches of Science, the Liberal and Fine Arts, Agriculture, Manufactures, and Commerce; For July, August, September, October, November, and December, 1825 To the practical ornithologist, who is desirous of promoting and extending his favourite study by the communication of his own personal observations and remarks, an intimate ac quaintance with the various notes of the feathered tribes is of such vast importance, that any difficulties he may encounter in obtaining it, will be more than compensated by the nume rous advantages it affords. In many instances it enables him to detect species that might otherwise elude his observation. Thus, the landrail, concealed in the long grass of luxuriant meadows, where it runs with great rapidity, and is sprung with difiiculty; the grasshopper warbler, closely embowered in thick hedges and bushy dingles, where it employs every artifice to escape notice; and the sedge warbler, secluded amid the reeds and other aquatic productions of pools and marshes are much more frequently heard than seen - the harsh call of the first, the sibilous note of the second, and the hurried song of the last, being repeated through the night, in fine weather, during the breeding season. It also enables him to identify species with the utmost pre cision: in some cases, indeed, with much greater certainty than he could by the minutest examination of good specimens. The three species of willow wren, for example, so strongly resemble each other, that even nice observers might have some difficulty in determining them by inspection; and, accordingly, we find that they have been the source of much confusion, perplexity, and error, among writers on ornithology. As their notes, however, are perfectly distinct, a little attention to them is sufficient to remove every difficulty. In the same manner, the crow may readily be distinguished from the rook, the raven from both, and the males of most species from the fe males.
