Beyond Mayfield: Measurements of Nest-Survival Data. SAB No. 34 plus 2 charts and 14Studies in Avian Biology No. 34. While surveys based on bird counts can measure changes in distribution and trends in abundance, these measurements have limited value in identifying factors that directly regulate populations. In addition, measures of abundance can be poor assessments of habitat quality or habitat selection. Investigations of parameters such as productivity, survivorship, and recruitment, as well as factors affecting these parameters,
