birdwatchers , who gathered to see a rare swallow on the angus coast were horrified , when they saw it snatched and eaten by a perigrine , they headed for lunan bay as word spread of a bird that was last seen frequently 20 years ago,,,,,,but the red rumped swallows which flew 1000,s of miles ,to get there probably with a mate, are no more because of the perigrine ,,,,,,,,,,nature brought these lovely little birds in ,,,,,and the rspb, destroyed them ,,,,,with their artificial spread of perigrines ,,,,, this is not the balance of nature
