Artist Nishant Jethi made a series called Living Typography to provide shelter for sparrows.
The artist says,
Study proves that there is a sharp decline in the number of house sparrows. The driving force is the lack of nesting and breeding spaces. With high-rises and malls coming up everywhere, the birds have been displaced.
So, an idea called ‘Living Typography’ was developed. Hollow wooden 3D alphabets that could also act as a bird’s nest were created. Appropriate alphabets were sent to a friends and family. They could keep it outside their house as their nameplate or house number. This nameplate/House number also acted as nests for birds amidst concrete jungle of the city.
