Quiet time in the British birding world, so I thought I'd ask a question: Has anybody ever mistaken a bird not just for another species but for something completely lifeless? So far I have managed to tick an M&S carrier bag (green woodpecker) a submerged tyre in a reedbed (gadwall) a hang-glider (white-backed vulture) and a half-eaten pizza (vermillion flycatcher). Not quite up to the standard of the visitor to Minsmere who id'd an Oystercatcher as a puffin carrying a carrot, I admit, but I'm working on it. Anyone else want to 'fess up?
