An incredible dolphin encounter in the Shannon Estuary!
While out on survey in the inner Shannon Estuary, near the Killimer Ferry crossing, the Shannon Dolphin Project research crew came across a large group of bottlenose dolphins.
At first, we thought the dolphins were busy foraging, but it soon became clear that something else was happening. As we watched, we realised we were witnessing a amazing display of social behaviour. At times, it looked as though the water was boiling with dolphins!
Encounters like this give us a valuable insight into the lives of the Shannon dolphins, helping us understand how they behave, how they interact with one another, and when and where these behaviours occur.
event: This weekend, Estuary Watch 2026 is taking place at watchpoints across the Shannon Estuary. Come along, join us on Saturday 22 August from 1–3pm, and see if you can spot some of these amazing bottlenose dolphins. Find your nearest watchpoint here: https://iwdg.ie/estuary-watch-2026/
🎥 Please note: The footage has been edited and zoomed in for viewing. During the encounter, our research crew adhered to the IWDG Code of Conduct, maintaining a respectful distance.
