Here is the only shot I got of my British Lifer Two-barred Crossbill! No complaints; what a cracking bird and I was so lucky to get a shot at all. This female has been frequenting an area on Leith Hill in Surrey and has been associating with a group of Common Crossbill. It was a 3 hour vigil but worth the wait. At one point I could hear Common Crossbill above my head but could also here a weird (to me) call. My best description is that it sounded similar to a Red-breasted Nuthatch of North America - 'sounds like a child's trumpet'. Anyhow, minutes later the Two-barred Crossbill made an appearance for about 30 seconds before flying off. My best guess is that it was the culprit.
