There is one tiny patch of our garden which an aggressive blackbird has
an obsession with! Early every morning he comes and digs away. You can
see his beak-marks in the earth. Maybe he has learnt that the spot, for
some reason, is rich in worms.

Anyway, he is dislodging little alpines and covering others with the
earth that he flings out of the way.

I'm wondering, is there any spray that I could saturate this small area
with so that he'll either get a whiff of it or a taste of it and bugger
off? I don't want to harm the little fella, but I do want to deter him
from constantly wrecking this particular patch of garden!

I find "Slug Clear" spray brilliant for keeping the slugs away from
certain areas. I don't suppose there's a "Bird Clear"?! :-)

Eddy.
