"You can know the names of a bird in all languages of the world,but when you are finished ,
You will know absolutely nothing whatever about the bird.....
So let`s look at the bird and see what it`s doing --that`s what counts.
I learned very early the difference between knowing the name of something and knowing something."

-Nobel Laureate Richard P Feynman(1918-1988)

InverteBlitz in Idukki Wildlife Sanctuary Successfully Completed

Cochin Natural History Society and Kerala Forest Department have conducted a Faunal Survey of the invertebrate fauna of the Idukki Wildlife Sanctuary on 14-16th March 2014. This was done using a new method of monitoring and documenting biodiversity in a given place using citizen volunteers and scientists and professionals. It is called InverteBlitz a modified form of BioBlitz which has been done in Aralam WildLife Sanctuary in the past. A bioblitz is an intense period of biological surveying in an attempt to record all the living species within a designated area (protected Area/Wildlife Sanctuary). Groups of scientists, Naturalists and Volunteers conduct an intensive field study over a continuous time period. There is a public component to InverteBlitz, with the goal of getting the public interested in biodiversity. Total of 18 participants from different parts of Kerala and from different backgrounds like Pharmacists, Mechanics, Sociologists, Doctors,Clerks,Entomologists(those who study insects in general),Myrmecologists(those who study ants) ,Odonatologits(those who study Dragonflies and Damselflies) Lepidopterists(those who study Butterflies),retired Engineers, Zoology students  all participated in the exercise.

The InverteBlitz was designed by Dr.Mohammed Jafar Palot, Scientist, Western Ghats Field Research Station, Zoological Survey of India, Kozhikode and Prof.Dr.Dilip K.G., President, Cochin Natural History Society. This survey was held with the assistance of Malabar Natural History Society and Travancore Natural History Society.
