In Bangalore a pair of wagtails lives on the patch of grass by the basketball hoop. They are a sheer pleasure to watch: they hop, daintily, about the grass, occasionally inclining their head to inspect a blade before jabbing it down, sword-like, to extract some hapless creature. Then they will turn, look up and contemplate the sky; perhaps in response to a movement they will take off and bob five meters in the air before coming down to land again, whereupon the process resumes. They are mime-like, black-and-white comedians of the grass.
