Paint your wall top with that black sticky gunk they use to keep pigeons
off
ledges.
Or, one better, put fake bird muck on the top of the wall - you could
probably make some fake stuff (anyone got any recipes?)

Why make life hard? Just spread a kilo of bird seed once a week or so, and
the birds will keep the wall well decorated with the real stuff. No kid
knowingly sits in bird shit.
