The protocol was created based on data collected through point
count method with parallel mist netting of four sites: reforestation
area, parang vegetation, disturbed montane forest and pristine
montane forest. Point counts were done by listing bird species
and number of individuals per station in a span of 15-20 minutes.
There were a maximum number of 12-point count stations per
site, spaced approximately 200 meters apart. Mist nets were
set adjacently per point count stations. The nets were layered
with ground nets (0-5 m layer) and sky nets (5-10 m, 10-15
m layers). Data collection was done from April 13-25 and July
9-17, 2003 at Mount Talomo, near Barangay Tamayong, Calinan
District, Davao City.
Field-testing of the crafted Upland Bird
Monitoring Protocol was conducted from September 19-25, 2003
at Sitio Utan, Upper Tamayong, Calinan District, Davao City.
The local participants surveyed birds along established monitoring
stations at the parang and disturbed montane forest. They
were instructed to record birds using their native dialect
in simple data sheets. They were to include what portion of
the trees the birds were found and the activity the birds
were performing at that instant.
A total of 90 species of forest-associated
birds were observed. Forty-one (41) of these birds were breeding
residents and 46 were endemic. Twenty (20) species of the
birds observed belong to the 58 threatened bird species in
Mindanao. Species richness was highest in parang vegetation
whereas percentage of endemics per site was highest in disturbed
and pristine montane forests. The data demonstrate high bird
endemicity in Mt. Talomo, which show that the environment
in the Talomo-Lipadas Watershed is still very viable for birds.
Forty-one (41) species out of the 90 observed
were chosen to be included in the Upland Birds Monitoring
Protocol based on current ecological status/threat category,
feeding guilds, tolerance to disturbance, conspicuousness,
local status/use and local names. These birds made up the
short list of indicator species. Of the 41 indicator species,
36 were accounted for by the local stakeholders during the
field-testing of the crafted protocol.
