Garden pests or wild nature?

Our little flock of hadedahs, whose raucous calling instils ire in everyone unfortunate enough to have them roost nearby, flapped back towards the shore just after sunrise this morning. They still don't realise that they aren't seabirds and have to stick to the land. They are, to me, one of nature's oddities - birds whose call grates on the ear, who eat the earthworms that we really want in our soil for essential aeration and fertilisation, and splatter our walls with copious amounts of yellow poop.  I think their most useful purpose is to amuse, as they sometimes fly around as if they are doing it for practice, with no set plan. When they fly out over the sea, it seems as though they suddenly realise that they have gone too far, and then the flock of fourteen flaps wildly, completely out of co-ordination, and make an about-turn, cackling inanely as they head back towards the safety of dry land.

They do make quite a pretty silhouette against the sky when roosting on the steeple-like roof next door, though.

That other garden pest, the throwing mole, has returned to the front lawn. I thought he had passed by on the way to the Kom, but this morning he threw up 8 mounds, each one a few feet closer to the fence. The fact that he is burrowing through sodden ground doesn't make any difference. His strength is incredible - to push out perfect tubes of almost solid earth shows great determination. What with the porcupine snuffling out from the top and the mole tunnelling below, I expect the lawn to be nothing more than a lattice of vegetation waiting to trap the unwary and twist an ankle.

I suppose it's our obsession with wanting to neaten up the natural vegetation that makes us have lawns and flowerbeds and plant things that shouldn't be there. If we left it as a wild meadow, we wouldn't have any stress from mole-heaps and porcupines. Perhaps that is the way to go?
