    ABSTRACT
    Mangrove habitat, microclimate, and human activities may affect avifauna species, especially, its diversity and distribution. This study aimed to assess the avifauna as affected by human activities, microclimate and mangrove factors in Barangay Pangayawan, Gitagum, Misamis Oriental. Point-count and mist-netting methods were used to sample birds, quadrat method for mangroves and microclimate factors were measured. Results showed 20 avifauna species which belong to eight (8) Orders and 17 Families, with a total of 1,056 specimens recorded in the site. In addition, four (4) mangrove species were identified under (3) Orders and (3) Families with a total of 239 specimens. Canonical Correspondence Analysis (CCA) was employed to determine the species-habitat relationship. Findings revealed that five (5) species of birds are closely associated with mangrove factors. It also showed that microclimate factors such as rainfall and relative humidity showed a negative correlation with avifauna diversity. However, human activities were observed in the site, hence, policies and ordinances should be strengthened and strictly implemented.
