Here's a recording I made on March 7th whilst walking in the Brecon Beacons. I did a circular walk up from the Taf Fechan Forest, then up the left hand side of the reservoir along Graig Fan Ddu, and over Corn Du, Pen Y Fan and Cribyn. Finally dropping down into the valley to join the far end of the reservoir.

Down in the valley near the Upper Neuadd Reservoir the whole area was alive with spring activity. There were many Frogs mating in drainage ditches and small pools. I heard the odd croaking as I was walking along, but every time I stopped and attempted to get nearer I frightened them away. However I later discovered they had also managed to reach the mountain pass between Pen Y Fan and Cribyn.

I managed to slide the microphone close to the edge of the pool and cabled back in order to not frighten them. Sadly I didn't have my hydrophone with me, but I love how the Frogs sound like much larger animals in this recording and the effect off the wind rushing across the mountain tops.
