EDITORS NOTE: This statistical report summarizing Bird-Banding at Grand Canyon National Park from the period of its inception, October 1932 to March 1934, was kindly prepared by Mr. Lester Stein of C. C. C. Company 819, who, as a member of the Museum Detail, has been recording bird-banding for the Park.
The value of this type of data is well shown in the following quotation from Mr. Frederick C. Lincoln of the Bureau of Biological Survey - "Any new field of research is usually divisible into three periods: First, experimentation, when methods are developed; second, data accumulation; and third, interpretation and report. Properly speaking, none of these has an ending, as the perfection of technique and the testing of new methods and refinements continue indefinitely, as may also the collection of usuable data. A starting point for the third period is, however, dependent wholly upon the successful prosecution of the other two, as obviously, no interpretation can be prepared until sufficient material has been obtained to permit proper evaluation."
