But one figure, low down on the cold north side of the building, had neither crown, mitre, nor nimbus, and its face was hard and bitter and downcast; it must be a demon, declared the fat blue pigeons that roosted and sunned themselves all day on the ledges of the parapet; but the old belfry jackdaw, who was an authority on ecclesiastical architecture, said it was a lost soul. And there the matter rested.
One autumn day there fluttered on to the Cathedral roof a slender, sweet-voiced bird that had wandered away from the bare fields and thinning hedgerows in search of a winter roosting-place.

Minimizing the environmental damage that new roads cause is generally regarded as a good thing. But to do that, it helps to understand just how new roads cause the damage of which they are accused.
Recently, a group of researchers led by Dr Gonzalez conducted an experiment which shows what ecologists have long suspected, but never been able to prove: that immigration is good for the health of animal populations.
A road destroys only a small part of the habitat it traverses, and thus annihilates just a few local populations of creatures. So the argument that road-building itself is bad for biodiversity is not self-evidently correct. Those who nevertheless hold this view usually point to a piece of ecological theory called "meta-population dynamics". This says that apparently separate local populations of animals are, in fact, parts of much larger populations connected via migration.
According to this theory, when a local population flounders &mdas
