Improving Methods for Regional Landbird Monitoring: A Reply to Hutto and Young
Ellingson AR and Lukacs PM. 2003. Improving Methods for Regional Landbird Monitoring: A Reply to Hutto and Young. Wildlife Society Bulletin. 31(3):896-902
Hutto and Young (2002) advocate an approach for regional-scale landbird monitoring that is based on convenience sampling and index values. We take issue with their methods and argue that convenience sampling and index values do not provide credible data from which to make inference about population dynamics. We clarify misconceptions of distance sampling from Hutto and Young used to dismiss the utility of the method. instead we propose that monitoring programs must address the issues of variable detectability and sound survey design, emphasizing rigor in all steps of the planning process.
