Abstract
Population trends of woodland birds were summarized from BBS data over 1966-1991, 1966-1979, and 1982-1991. For the entire woodland bird assemblage, increasing species outnumbered decreasing species in all regions except central North America during 1966-1991. However, the proportion of decreasing species increased in most regions during the 19821991 interval. This population trend was most apparent for Neotropical migrants with 15 increasing and 2 decreasing species during 1966-1979 but only 4 increasing and 16 decreasing species during 1980-1991. Short-distance migrants and permanent residents had nearly equal numbers of increasing and decreasing species during both intervals.
