This pigeon is foraging in a hole in the wall of the library at Bishop's College in Kolkata. I am not sure whether he was chasing bugs or seeking a crevice for a new home.
What faith...that this wall could yield something of creature comfort. But there was a lot of that in India. There were so may places where someone had made "a silk purse from a sow's ear." Houses were built from an amazingly diverse range of "building materials." Trash was combed over for the very lasts bits of usefulness.
What could the world around us yield if we had the faith to look and expect to find what we need?
