What have Wales’ coastal otters been eating ?

MISE project have been collecting and analysing otter spraint from the Welsh coast to find out what otters have been eating in the area. The full results aren’t in yet, but I can tell you that Welsh otters are eating all these things: eels, wrasse, bullrout, sticklebacks, frogs, birds and mice. I participated in a workshop at Treborth Botanic Garden as a volunteer and spent the day picking prey remains out of spraint and sorting them for identification.
I even found almost intact woodlice in one sample, although we’re pretty sure they must have come from the gut of the unfortunate bird whose remains dominated the Petri dish.

The workshop was led by Rob Strachan (EA Wales).
