A recent comprehensive bird survey in Silent Valley National Park has recorded 192 bird species, highlighting the rich avian biodiversity of this ecologically sensitive rainforest region. The findings reaffirm the park’s status as one of India’s most important biodiversity hotspots.
Location and Geography
Silent Valley National Park is located in the southwestern part of the Nilgiri Hills in the state of Kerala. It forms a crucial part of the Nilgiri Biosphere Reserve, which is recognized as a UNESCO World Heritage Site.
The altitude of the park ranges from 658 meters to 2,383 meters, creating diverse ecological conditions.

The park features multiple vegetation types, including:
-
West Coast tropical evergreen forests
-
Sub-tropical broad-leaved hill forests
-
Montane wet temperate forests
-
Grasslands
