The sudden death of swarms of starlings in British Wales raised suspicions as to why this happened, which prompted local authorities to open an investigation into the matter, according to the website The Sun.

The lady noticed the swarms of the fold on her way to see a doctor, but she was surprised by the same swarm lying on the ground an hour after her return, while she estimated the number of dead birds at more than 300 birds.

The Royal Society for the Protection of Birds said the incident was cause for concern, as the starlings are an endangered animal.
