Reaching new heights

This user-friendly app does a thorough job of documenting the birds in the country. You get a checklist of species found in different cities like Mumbai or Bengaluru thanks to a bird-distribution map. There is also a Q&A forum where experts answer queries, and there is added data about the different levels of elevation that birds fly at. Dalvi, who conceptualised Vannya, tell us, "Let's say there is a ferry bird. It can fly at 1,500m above in a place like Maharashtra. But that same elevation drops to 300m in the Himalayas, and having such information helps you spot and photograph them based on your location."
