A walk around Norwick where I managed to sound-record the Common Crossbills with the resulting sonogram revealing they were 'Glip' Common Crossbills being the only call-type I've ever managed to record on Shetland.
Norwick: Knot, 2 Snipe, Swift, Pied Wagtail, 3 Wheatear, Common Whitethroat, Willow Warbler, Pied Flycatcher, Red-backed Shrike & 5 Common Crossbill.
