Hamburg Wadden Sea National Park

Popular

The Hamburg Wadden Sea National Park is a protected area located in the North Sea off the coast of Hamburg, Germany. It is part of the larger Wadden Sea, a UNESCO World Heritage Site, and is known for its vast tidal flats, salt marshes, and diverse marine life. The park is home to a variety of marine species, seals, and fish that thrive in the unique intertidal environment.

Harbor Porpoise
This small, shy cetacean is one of the few whale species that inhabit the North Sea year-round. Harbor porpoises are often seen in the waters around the Wadden Sea, where they hunt for fish like herring and sand eels. They are known for their low, rolling movements rather than dramatic leaps.

Common Seal
Also known as the harbor seal, this species is one of the most iconic marine mammals in the Wadden Sea. Common seals use the sandbanks of the national park to rest and give birth, and they are skilled hunters, feeding mainly on fish and crustaceans.

Grey Seal
Larger than the common seal, grey seals are another important marine predator in the park. They have a more elongated snout and are known for their loud, haunting calls. They are often spotted on remote sandbanks and are particularly visible during pupping season in winter.

European Eel
This critically endangered species is an important part of the Wadden Sea ecosystem. The European eel has a fascinating life cycle, migrating thousands of kilometers between the Sargasso Sea and European rivers. In the tidal channels of the Wadden Sea, young eels, known as elvers, grow before making their long journey back to spawn.

Common Shrimp
A crucial part of the Wadden Sea’s food web, the common shrimp is a small but highly abundant species. It serves as a food source for many fish and birds and is also commercially fished in the region. These shrimp are well-adapted to the changing salinity and tides of the national park.

Atlantic Herring
A key fish species in the North Sea, Atlantic herring is an essential food source for many of the park’s predators, including seals and seabirds. These fish travel in large schools and play a vital role in the marine ecosystem.

Lesser Weever
This small fish is known for its venomous spines, which can cause painful stings if stepped on. Lesser weevers bury themselves in sandy seabeds, waiting to ambush small prey. Though not aggressive, they are a species to be cautious of when wading in shallow waters.

European Flounder
A type of flatfish, the European flounder is well-adapted to life in the Wadden Sea’s shifting tides. It can change color to blend into the seabed and is an important prey species for larger fish and seabirds.

Sand Goby
A small, bottom-dwelling fish, the sand goby thrives in the intertidal zones of the Wadden Sea. It plays a key role in the ecosystem by feeding on tiny invertebrates and serving as food for larger fish.

North Sea Crab
Also known as the edible crab, this species is an important scavenger in the Wadden Sea. It has a hard, reddish-brown shell and powerful claws used for cracking shells of mollusks. The North Sea crab is also of commercial value to local fisheries.

Birds

The Hamburg Wadden Sea National Park is a vital stopover point for millions of migratory birds traveling along the East Atlantic Flyway. Its vast mudflats, salt marshes, and tidal areas provide abundant food sources, making it one of the most important bird habitats in Europe.

Eurasian Oystercatcher
Recognizable by its black-and-white plumage and bright orange bill, the Eurasian oystercatcher is a common sight along the Wadden Sea. These birds use their strong bills to crack open shellfish like mussels and cockles, making them a key species in the ecosystem.

Common Redshank
This elegant shorebird, with its long red legs and speckled brown body, is frequently seen wading through shallow waters in search of worms and small crustaceans. Its distinctive, high-pitched call makes it easy to identify.

Bar-tailed Godwit
One of the Wadden Sea’s most impressive migratory birds, the bar-tailed godwit undertakes one of the longest nonstop flights in the bird world. It breeds in the Arctic and spends its winters in Europe and Africa, refueling in the Wadden Sea during migration.

Dunlin
This small sandpiper is one of the most numerous wading birds in the park. Dunlins form large flocks that move in synchronized patterns above the tidal flats, feeding on tiny invertebrates hidden in the mud.

Eurasian Curlew
With its distinctive long, curved bill, the Eurasian curlew is an unmistakable sight in the Wadden Sea. It uses its specialized bill to probe deep into the mud for worms and crustaceans. Unfortunately, this species is declining due to habitat loss.

Brent Goose
A winter visitor to the Wadden Sea, the brent goose is a small, dark-colored goose that feeds on eelgrass and algae. Large flocks of brent geese can be seen grazing in the salt marshes during migration.

Shelduck
A striking waterfowl with a black, white, and chestnut-colored body, the shelduck thrives in the Wadden Sea’s shallow waters. These ducks are unique because their ducklings are often raised in communal “nurseries.”

Great Black-backed Gull
The largest gull species in the Wadden Sea, the great black-backed gull is a formidable predator and scavenger. It preys on fish, smaller birds, and even seal pups when given the chance.

Little Tern
One of the smallest terns in Europe, the little tern is a summer breeder in the Wadden Sea. It has a sharp, high-pitched call and is known for its spectacular aerial dives to catch small fish.

Avocet
With its elegant black-and-white plumage and upward-curving bill, the avocet is one of the most iconic birds of the Wadden Sea. It sweeps its bill from side to side in shallow water to catch small invertebrates, a feeding behavior unique among wading birds.

The Hamburg Wadden Sea National Park is an exceptional habitat that supports a diverse range of marine and bird species. Its rich intertidal ecosystem is crucial for both resident and migratory wildlife, making it a vital conservation area in northern Europe.
