App Goes Mad

As some readers might recall, I recently took a step into the 21st century (more fool me) by buying an 'app' for my mobile that claims to identify birds from their songs. Initially it worked quite well, and helped me to distinguish the songs of various warblers. Since then, however, it appears to have developed a mind of its own, and that mind has become increasingly deranged. Among the latest birds it has kindly identified for me have been the (American) Great Horned Owl, the Australian Reed Warbler, the (American) Chimney Swift, and a wildly improbable Crossbill. I look forward to confident identifications of the Phoenix and the Roc, maybe the Dodo...
