Of the residents, 40 are endemic to the Philippines while 16 are restricted only to Mindanao. Twenty-two species currently listed as threatened were also encountered. It is recommended that additional surveys employing a more standardized methodology should be conducted in order to adequately determine bird species diversity, abundance and distribution
