Title: Terminology used in estimating number of birds

Author: Ralph, C. John;

Date: 1981

Source: Studies in Avian Biology 6:577-578

Publication Series: Miscellaneous Publication

Description: Hundreds of papers, such as those presented in this volume, are produced annually by workers using various techniques. The purpose of this section is twofold: (1) to provide for readers unfamiliar with counting techniques a handy guide to the most common terms and methods used in the field; and (2) to attempt to set a consensus on the meanings of some terms that are too commonly used interchangeably in the literature. I have not attempted to set arbitrary standards here; rather, if two or more terms are commonly used to apply to the same method or unit, and if each is unambiguous, then I have indicated this synonymy.

Publication Notes:

  • We recommend that you also print this page and attach it to the printout of the article, to retain the full citation information.
  • This article was written and prepared by U.S. Government employees on official time, and is therefore in the public domain.
