One of the first sounds you'll hear when you visit our Wetland Centre is the distinctive call of our Eider Ducks. Instead of the typical "quack" of a mallard, the Eider's have a unique "aah-woo" sound 🔊🎶 This large sea-duck is the UK's heaviest duck and is a firm favourite at the centre - their regular displays and singing always brings a smile to our face! Come and hear them for yourself - visit us today! | WWT Martin Mere Wetland Centre

🪶 Eiderdown: The world’s softest and warmest feather! Harvested from eider duck nests without harm, it's rarer than gold. #Eiderdown #LuxuryFeathers #NatureFacts | Facts that will blow your mind

The eiderdown is a type of down feather, which is a soft and fine layer of feathers located under the eider duck's tougher exterior feathers. It stays dry thanks to the air trapped within and it's the only kind of down that these ducks naturally shed during molting.
