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

  • Erica H. Dunn
  • David J. T. Hussell
Part of the Current Ornithology book series (CUOR, volume 12)


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.
