Greetings --

BBC NEWS / SCIENCE & ENVIRONMENT today carries a story titled "Feeding
birds 'changes evolution'" which leads off... "Bird-feeders, hung in
many a garden, can affect the way our feathered friends evolve, say
scientists.

"European birds called blackcaps follow a different "evolutionary path"
if they spend the winter eating food put out for them in UK gardens."
