In a survey held at Grizzled Giant Squirrel
Sanctuary
Twenty species of rare, endemic and migrant
birds have been recorded in the Grizzled Giant Squirrel Sanctuary in
Srivilliputhur during a recently concluded bird survey.
S. Chandrasekaran, Member of the Bombay Natural
History Society, who was part of the survey, said the rare endemic species
included Sri Lankan Frogmouth, Mountain and Rufous-bellied Hawk Eagles, Great
Indian and Malabar Pied Hornbills, Mountain and green imperial pigeons. These
species were found only in the high altitudes of Western Ghats.

Steppe Eagle, Eurasian Sparrowhawk and
Bluecapped Rockthrush were some of the rare migrants recorded in the sanctuary
during the survey, Mr. Chandrasekaran said.
A total of 10 camps were pitched in the four
ranges of the sanctuary — Watrap, Saptur, Srivilliputhur and Rajapalayam — for
the survey, which was held on December 23 and 24 last year. Each camp had an
ornithologist assisted by a few students from local colleges along with two
forest guards/watchers.
The camp sights were selected in such a way that
all kinds of habitats were covered during the survey and the locations also had
some place to stay during the night hours, he said.
The survey was divided into three sessions — two
on December 23 and one on 24. The data was mainly collected for statistical
analysis and to estimate the abundance of bird species in the sanctuary.
However, the participants were allowed to record birds sighted during other
times, which would help in preparing a checklist, said T.S. Subramania Raja of
the Wildlife Association of Rajapalayam, which organised the survey.
