The PRA included a profiling of the birds and arboreal andlarge mammals of the ancestral domain AD) of the Obu-Manuvu tribe at Barangay Carmen,Baguio District, in Davao City.
Results of this expedition suggest that the AD harbors a diverse and unique vertebrate fauna. At least 67 species of forest vertebrates were documented: 60 birds; 3 diurnal and arboreal mammals; 2 nocturnal and arboreal mammals; and 2 large mammals. Thirty five percent (23 species) of these vertebrates are endemic to the Philippines.
