The work in which this supposed discovery was announced was published in 1844, four years after the second edition of Nuttall’s ‘Manual’ appeared. Since this manual was the first American work on ornithology, excepting Wilson’s, to go into a second edition, it was presumably widely known among ornithologists, and it is not easy to understand why Audubon and his coworkers were in ignorance of their lack of claim to Nuttall’s Mourning Finch.
During the twenty-five or thirty years following Audubon’s visit to the Missouri haunts of the Sparrow, practically nothing was learned of its life-history or distribution, and the few scattered specimens that were taken were all from the same general region. A specimen furnished by Lieut. Couch, taken at Fort Leavenworth on October 21, 1854, formed part of the material used by Prof. Baird in his epochal work in 1858, as did another taken at the same point on April 21, 1856, by Dr. Hayden, of Lieut. Warren’s Pacific Coast Surveys party. Dr. Hayden took three other specimens further up the river in the same year. Dr. P. R. Hoy, who collected in the type region in 1854, took a specimen on May 7, and on May 13 met with a troop of fifteen or twenty. There are a few other records from the Missouri Valley and one from Texas (Dresser, Ibis, 1865) prior to the numerous ornithological activities of the early seventies. Dr. J. A. Allen, collecting in the interest of the Museum of Comparative Zoölogy, had his headquarters at Fort Leavenworth during the first ten days of May, 1871, and found Harris’s Sparrows exceedingly abundant in the bottom timber on the Missouri side of the river. He added a few field notes on behavior, appearance, etc, and took a series of specimens. Baird, Brewer, and Ridgway state that from the time of its discovery in 1834 up to 1872 but little information had been obtained in regard to the Sparrow’s general habits, its geographical distribution, or its mode of breeding, single specimens only having been taken at considerable intervals in the valley of the Missouri and elsewhere. In 1874 Dr. Coues brought together all the available data in his interesting article on the bird in ‘Birds of the Northwest,’ but was able to add nothing in determining the bounds of its habitat, which he gave as “Region of the Missouri. East to Eastern Iowa.”
It was not until ten years later that enough information had accumulated to warrant an attempt at defining the limits of its range and the periods of its migration. This was done by the painstaking and accurate Wells W. Cooke in the first volume of ‘The Auk,’ in 1884. In this article, ‘Distribution and Migration of Zonotrichia querula,’ he was able only in a very general and indefinite way to give the western and southern extent of the range, but the eastern limits remain practically as he defined them.
In 1913 Professor Cooke noted the interesting peculiarity of the migration of the Harris’s Sparrow in the interval that elapses after the first spring advance. He states[11] that the birds become common along the Missouri River in northwestern Iowa soon after the middle of March and yet it is not until early May that they are noted a few miles further north in southeastern South Dakota and southwestern Minnesota. He adds that the dates suggest the probability that these March birds have wintered unnoticed in the thick bushes of the bottomlands not far distant, and have been attracted to the open country by the first warm days of spring. This theory is borne out by the facts as observed by the writer in the Kansas City region. The birds are present in this vicinity during even the most severe winters, but keep to the dense shelter of the Missouri bottoms. During mild and open winters a few scattered flocks may even spend the entire season until spring in the hedges and weed patches of the prairie country.
This Sparrow has always attracted attention in the field by its large size and conspicuously handsome appearance, as well as by its sprightly and vivacious manner and querulous notes, but it has seldom been the subject of special notice in the literature of American birds. Its bibliography is chiefly confined to diagnostic listing in formal works on ornithology, brief annotations in faunal lists, and occasional mention in published field notes.
During the thirty-four years that have elapsed since Prof. Cooke’s article of 1884, the Sparrow, as a migrant, has become well known to ornithologists. Its narrow migration path, the center of which in the United States is approximately down the 96th meridian, has been worked out; the wide extent of territory covered by stragglers has been fully reported;[12] the food habits of the bird while on migration have been thoroughly investigated and the results published;[13] the nest has been seen once,[14] and young just out of the nest have been collected,[15] and the general region of the breeding ground itself is known to be where barren tundra meets the edge of the timber between Hudson Bay and Great Bear Lake. But the eggs yet remain to be discovered.
