Abstract: | We compared number of avian species and individuals in morning and evening point counts during the breeding season and during winter in a bottomland hardwood forest in west-central Mississippi, USA. In both seasons, more species and individuals were recorded during morning counts than during evening counts. We also compared morning and evening detections for 18 species during the breeding season and 9 species during winter. Blue Jay (Cyanocitta cristata), Mourning Dove (Zenaida macroura), and Red-bellied Woodpecker (Melanerpes carolinus) were detected significantly more often in morning counts than in evening counts during the breeding season. Tufted Titmouse (Baeolophus bicolor) was recorded more often in morning counts than evening counts during the breeding season and during winter. No species was detected more often in evening counts. Thus, evening point counts of birds during either the breeding season or winter will likely underestimate species richness, overall avian abundance, and the abundance of some individual species in bottomland hardwood forests. |
