flight of parakeets

Sure, you can't really see them.  I promise they were there - see below (from the same image).  But try imagining what they sounded like, screeching across the morning sky.  For some reason (nothing that they like to eat, I suppose), we don't ever see them in our back yard: these are down the street.  There are, indeed, more parakeets visible in my parents' back yard in Wimbledon, which doesn't seem right to me.  But with so many bird species here that are different from England (apart from sparrows, and they are unthinkable, to quote E. M. Forster), I invoke parakeets as some kind of tenuous avian link between the two places.
