About 35 yards from the window of my tiny office is a flat-roofed two storey rear extension on the house opposite. There's a rainwater hopper that channels the water from the roof into a downpipe. About five weeks ago I noticed a pair of fairly manky urban pigeons regularly disappearing into the hole in the brickwork that feeds the hopper, presumably to build some kind of nest.
Yesterday, I gazed out and saw a large crow sitting on the edge of the hopper, reach into the brickwork, and come out with a tiny flapping bit of pigeonkind in its beak. It then flew to another flat roof nearby and started pecking enthusiastically. Magpies followed.
An hour later, one of the victim's parents was sitting nearby the nest waiting. It stayed virtually immobile for well over an hour, seemingly not noticing the crow returning to the adjacent roof and flying off with a tiny, lifeless, limp dead pigeon in its beak. I know that a crow's gotta do what a crow's gotta do, but the body language of the waiting adult pigeon was utterly pitiful.
Red in tooth and claw.
