Using Migration Counts to Monitor Landbird Populations: Review and Evaluation of Current Status

  • Erica H. Dunn
  • David J. T. Hussell

Abstract

Increased knowledge of North American landbird populations and concern for their status (e.g., Robbins et al., 1989; Askins et al., 1990; Askins, 1993) has led to greater interest in methods of monitoring population change in nongame birds. Without monitoring we are unable to document long-term change, to determine whether short-term fluctuation is within a normal range, or to evaluate the effectiveness of management.
