Aren't sounds brilliant!

Having recently acquired sound recording equipment (unfortunately too late to record the much debated Dump Clump Yellow-browed Warbler, or to attempt the putative Syke's Warbler) Bob and I are making our first forays into a more detailed appreciation of bird vocalizations - sonograms. It was pleasing therefore, to record a group of Common Crossbill in the pine belt at Trenoweth and confidently assign them to type: Type C or Glip Crossbill (see sonogram below).
