Ten of them looking all ways

I don't especially like pigeons, or rock doves, whatever you call
them. They hang about on edges of roofs leaving their crap behind
them, and they spill birdseed I leave out for tinier birds, so it goes
all over the ground, no doubt attracting other pests.

They sometime look very ominous, like so many crows, but crows strike
me as much smarter animals.
