Bird ringer and a keen nest recorder Craig Cerrig Gleisaid searched the Brecon Beacons for a Raven’s nest and came across a Peregrine Falcon roost site. After squeezing the pellets and finding bird rings inside he soon realised a Metal Detector would cut down his search time.
“I visited another Peregrine site the following day and found a Dutch ring. Then, a thought hit me, what if I searched at these sites with a metal detector? It was getting close to the Peregrine nesting season, so I had to leave it until the following autumn/winter, when they had finished breeding, before I searched again, this time armed with a cheap metal detector.” – Extract from Text
