Birdwatchers of the world unite to hear a dawn symphony

The International Dawn Chorus Day --Royal Society for the Protection of Birds' Garden Birdwatch project : "Some will be hoping for the mellifluous melody of the blackbird, others the liquid warble of the robin and still more the raucous, tuneless cry of the house sparrow. Whatever the preference, the promise of a memorable dawn chorus will be enough to attract hundreds of people this weekend for an annual communion that is drawing a growing number of avian devotees."
