Most of the endemic bird lives of the upper Western Ghats plateaus are found in the shola interiors rather than the grass lands. The black and orange fly catcher, Nilgiri Wood Pigeon and Grey-breasted laughing thrush are all shola species. The rare Broad tailed grass bird is found at lower elevation grass lands. There are a whole group of snakes, the shield tails, which are almost entirely confined to the Western Ghats and hills of Sri Lanka. Several of these are exclusively shola species. Mammals endemic to the Western Ghats like the Nilgiri Marten, Nilgiri Langur, dusky-squirrel etc. are also found here. Nilgiri tahr prefers grassy habitat with a clear field of view. They will only enter sholas when appropriate cliffs are unavailable to them.
