What do Common Murre eat?

What do Common Murre eatThe Common Murre can venture far from its breeding grounds to forage; distances of 100 km and more are often observed though if sufficient food is available closer by, birds only travel much shorter distances. The Common Murre mainly eats small schooling forage fish 200 mm long or less, such as polar cod, capelin, sand lances, sprats, sandeels, Atlantic cod and Atlantic herring. Capelin and sand lances are favourite food, but what the main prey is at any one time depends much on what is available in quantity. It also eats some molluscs, marine worms, squid, and crustaceans such as amphipods. It consumes 20-32 grams of food in a day on average. It is often seen carrying fish in its bill with the tail hanging out.
The Snake Pipefish is occasionally eaten, but it has poor nutritional value. The amount of these fish is increasing in the Common Murre's diet. Since 2003, the Snake Pipefish has increased in numbers in the North-east Atlantic and North Sea and sandeel numbers have declined.

 

 

Common Murre description:

The Common Murre or Common Guillemot (Uria aalge) is a large auk. It is also known as the Thin-billed Murre in North America. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North-Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.
Common Murres have fast direct flight but are not very agile. They are more manoeuvrable underwater, typically diving to depths of 30–60 m (100–200 ft), and depths of up to 180 m (600 ft) have been recorded.
