Number of birds per species/100 ha/day, number of individuals of all species combined/100 ha/day, and number of species on the State Game Lands 33 Research and Demonstration ROW and in the adjacent forest during four time periods (June 2000, August 2000, June 2001, and August 2001) and for all periods combined. Only those species present on the ROW during at least three periods are included in this table (a complete list is available from Richard Yahner). Surveys were conducted for 6 days; the total area of the ROW and forest surveyed was 6.87 ha (17 ac). Species are listed in phylogenetic order. Common species (≥50 individuals/100 ha/day) are given in bold.
