In Asian cultures birds often symbolise immortality. In Indian myth birds represent departed souls and in Christian art birds often appear as saved souls. Some people say when you find a dead bird the meaning is someone you loved passed away.
Others say that dead birds actually are a good sign, showing you that an end to turmoil or pain is coming. A dead bird doesn’t necessarily portend physical death, but metaphorical death. Perhaps you’re going through the heartache of a break-up. Perhaps you are struggling to find a job. This dead bird marks the end to your search and struggle. A new beginning is just around the corner.
None of the mentioned happened (at least I did not notice) when I found this bird in my garden in Clapham, London. HDR applied.
