In order to up-date the current information on the status of Sri
Lanka's 4 primate species (slender loris, hanuman langur, purple-face
langur, toque macaque) I continued efforts in the collection of nation
wide questionnaire in collaboration with my Sri Lankan counter parts. We
also selected national parks and other places in areas particularly scant
in detailed information about these primates to conduct on-site
observations and fecal sample collection. We left Colombo on 5 February
for Bundala National Park in the south. There between 5 and 7 Feb., we
observed toque macaques and gray langurs. Between 7 and 9 Feb. we visited
four temple complexes: Vadasitikanda, Sellakataragama, Kataragama and
Situlpawwa. Here we collected fecal samples from troops of toque macaque
and hanuman langur when encountered. From 9 to 12 Feb. we stayed in Yala
NP and conducted surveys and collected fecal samples from toque macaques
and hanuman langurs. We next moved north to Udawalawa NP and stayed there
between 12 and 14 Feb. were we again observed toque macaques and hanuman
langurs. From 14 Feb. we moved further north to the highlands of Horton
Plains NP, the highest national park in Sri Lanka. Between 14 to 17 Feb.
we conducted surveys on the high-altitude sub-species of purple faced
langur (bear monkeys). On 18 Feb. we visited the Kandy City suberbs,
Udawatta Kele Nature Sancturay and the Peradeniya Botanical Gardens to
collect toque macaque fecal samples and conduct questionnaires on local
residents. On 19 Feb. we visited Dambulla in the north central part of the
island site to collect toque macaque fecal samples. This temple complex is
a World Heritage site. After completion of this work, I traveled to
Bangalore, India, visiting the National Institute of Advanced Studies and
the National Centre for Biological Studies- Datta Institute of Fundamental
Studies and exchanged information and presented two lectures to members of
these institutions. Together with my local counterpart, Prof. Anindya
Sinha and his student we traveled to Bandipur National Park in the south
and observed bonnet macaques, a close genetic relative of Sri Lanka's

our driver Mr. Ruwan and Mike Huffman at the entrance to Horton Plains National Park.
