I’m enjoying my high-definition BBC feed while I still have it. Recently, I enjoyed a documentary about Madagascar narrated by Sir David Attenborough. He mentioned a rare carnivore called Grandidier’s vontsira (BBC, Island of Marvels, Part 3. YouTube clip, 0:12:08–0:13:24). I had never heard of it, and no wonder. It’s a rare mongoose found only in a tiny part of Madagascar. It’s like the mammalian equivalent of a snail darter, a tiny fish found only in certain rivers.
It took a little while for me to find out more. It’s more commonly called Grandidier’s mongoose. It was named only in 1986 and little is known of its life. It’s adapted to an arid climate, eats small prey and insects, and pairs off to have one offspring. If you watch the video clip, you’ll hear its voice, distant whistles and then a cross between a mew and a coo.
Most of the prey items caught are insects but the greater biomass, 57% – 80% depending on the season, comes from small animals.
The range map for Galidictis grandidieri is from Wikipedia, and ultimately from the IUCN Red List of Threatened Species, species assessors and the authors of the spatial data.
