The Family and I were new birdwatchers a decade back when we visited Patna one October. We were told that just east of the city, in a place called Danapur, one can see trees full of birds. Just the previous year The Family had bought a field guide to birds by Salim Ali, and I had bought my first digital camera. We drove out along the Khagaul-Danapur road, turned right near the Ganges, and almost immediately saw several trees full of storks. Today we know that such a group of trees is called a heronry. Year after year, generation after generation, herons and storks will come back to their heronry to breed.
We were amazed. My five-year old niece, who was with us, was stunned. I took photos. When we came back home, The Family brought out her field guide, and patiently leafed through it, with my niece at her shoulder, trying to identify the bird. It turned out to be the Asian open billed stork. This was what bird watchers call a lifer: the first sighting of a species. We never forgot that it is called "open billed" because there’s always a gap between its bills. We saw it many times later, but this was the only heronry of this species that we ever saw.
