Abstract: Bird banding was the most important technique for studying and identifying individual birds. Population estimates and population density trends are crucial elements in wildlife management and conservation. Especially bird population trends are good indicators of biodiversity and the environment. This study was conducted to monitor and estimate the population density of understory birds in 16 ha of permanent plots in lower montane evergreen forests at Mae SaKog Ma Biosphere Reserve, Chiang Mai Province. Birds were sampled using mistnetting at 12 gap sites for five years, from October 2014 through October 2019. The results show that 1,813 individual birds were caught, representing 82 species, with 330 individual birds recaptured in 38 species, which were classified into four avian feeding guilds. Insectivores were the most abundant guild for natural gap and closed canopy sites. Frugivorous and nectarivorous birds were prevalent in gaps. Frugivore and insectivore feeding guilds increased over time but more rapidly in forest gaps than in closed-canopy habitats. The detection probability of birds was higher in forest gaps and increased more quickly in gaps than in closed-canopy habitats, possibly due to gap succession. My findings suggest that natural forest gaps and gap age play an essential role as a temporal inhibitor to the rapid bird population decrease in the lower montane forest, which the management successfully affects depending on the period.
