For the final time this season, my friend Niaz and I are on a boat on the Padma in Rajshahi. We are watching birds in the chars. As I look through my camera at a small bird skipping along in the mud, I hear a loud racket approaching overhead. “Bar-headed! Bar-headed!” cries Nuru, our boatman. The V-shaped formation of Bar-headed Geese flaps wings in perfect synchronicity. It continues its flight over the shoreline past our boat and disappears.
