I’m sorry to hear that, it’s a terrible news for our biodiversity. It’s likely that the birds succumbed to starvation or exhaustion while seeking food during harsh winter months. However, human activities such as pollution, fishing, and climate change can also greatly impact the seabird population. In such situations, authorities typically conduct post-mortem analyses to determine the exact causes of death. If you are interested in helping, consider donating or volunteering with organizations focused on protecting marine life and biodiversity.
