The decision has been taken to create awareness among people about these small birds which are vital for the eco system but are facing threat.
The campaign will also be supported by international organisations such as Eco-Sys Action Foundation (France), Avon Wildlife Trust (UK), Cornell Lab of Ornithology (USA) and numerous other institutions around the world.
Reports have shown that over the years the population of sparrow has been on a continuous decline due to changing architectural practices, diminishing green-cover, changing life-style and the increasing number of mobile towers and its radiation.
Sparrow is a vital part of the eco system as they survive on insects and bigger birds survive on them. Experts have pointed out that if their number decreases their will be a negative impact on the entire natural cycle.
To promote the campaign and create awareness, BNHS has also launched a website called www.worldsparrowday.org.
The website provides information about 22 out of 26 sparrow species including rare photographs. Further information of events on bird related issues taking place across the world will be made available on the website.
