I captured birds in a central Guatemalan cloud forest (Sierra Yalijux) in two adjacent habitats, with different
habitat structure to assess the influence of land use on bird populations. The regional population of Common Bush-
Tanager (Chlorospingus ophthalmicus) showed a pattern of spatial separation of 1st-year individuals vs. adults, a pattern
not shown so far for any bird species. During the early post-breeding season, I captured similar numbers of adult
individuals in both natural and young secondary forest (38 vs. 43), while 1st-year individuals were captured mainly in
young secondary vegetation (3 vs. 40). The findings indicate that inexperienced, young or less competitive individuals
may use other habitats than adults, at least temporarily.
