Overview

Otters have recovered well in northwest England following water quality improvements, and the Sefton Coast's network of drainage channels, pools and ditches provides good habitat. They're rarely seen but signs — spraint (droppings) on prominent rocks and bankside, footprints in mud, fish remains — are more frequent. A sighting at Marshside RSPB is an exceptional event but has been recorded.

Frequently Asked Questions

How do I find signs of Otter on the Sefton Coast?

Otter spraint (droppings) is the most reliable sign — it is left on prominent rocks, bridge buttresses and bankside vegetation as territorial markers. Otter spraint has a distinctive fishy, musky smell and contains fish bones and scales. Footprints in soft mud (5-toed, star-shaped with webbing) are also diagnostic.
