Practical work : Contamination of marine birds How do affects marine birds marine pollution ? Plastics at sea : another threat to seabirds Plastic pollution is a known threat -but not very estudiada- in ocean ecosystems worldwide . As Jacob González -Solís , "this is the first study that quantifies the consumption of plastics in seabirds in the Mediterranean, a fragile ecosystem , with industrialized coasts, heavy maritime traffic and densely accumulated plastic " explains .

The sea is not a dump

Accidental ingestion of plastics is a global problem affecting species as different latitudes as the Laysan albatrosses ( Laysan albatross ) , in the archipelago of the Hawaiian Islands in the Pacific Ocean , or the fulmar ( Northern fulmar rodgersii ) . " The plastic float and are difficult to degrade ," warns González -Solís . " All pollutants are not destroyed on the ground eventually reach the sea over time. And he stresses the sea is not a dump. Maybe it has improved the level of control in the manufacture and transport of plastics on an industrial scale , but would have to establish greater control


of the discharge of plastics and not tolerate that ships directly throw garbage into the sea ".

Penguins Predators depend on where these are some of the most common are the leopard seals, snakes, foxes, sea lions, sharks and even killer whales. They also suffer at the hands of humans because they are hunted indiscriminately, they are also caught in large fishing nets out there when we are trying to catch their own food. A penguins do not care cold as many might think, since they have several layers of fat in their bodies that protect them from this. However many overheat, and that's a concern. Due to global warming this has become a major concern, often spread their wings so as to be cooler, also spend more time in the water when it's too hot for them ashore. There are many types of penguins around the world, some of them being around laextinci贸n, while others are considered very vulnerable species at present, few seem to survive because they are able to constantly adapt to the environment as you need . When we allow the destruction of their natural habitat, we are making it harder survival of these magnificent birds, this includes water pollution where penguins swim and hunt for food when chemicals, petroleum, and even garbage found in its waters, Penguins often die because of this.


Humboldt Penguin This is an average sized penguin with an adult weight of no more than 13 pounds. When mature a black band will develop in the chest.

Macaroni penguin You will be able to distinguish the macaroni penguins from other species due to the colors of the feathers on the top of


their heads are yellow and black , and very intense colors.

The

Atlantic puffin has a black crown and back, pale gray cheeks and "pants" white. It is wide, with a red and black beak visibly marked and orange legs that contrast with their plumage. The puffin is a species of bird Charadriiformes the Alcidae family.It is the only native Atlantic Puffin; two related species, the Tufted Puffin and Horned Puffin, are located in the northwest Pacific.The Atlantic Puffin breeding in Iceland, Norway, Greenland, Newfoundland and many islands in the North Atlantic. In the South and West, his acividad reaches Maine and British Islands in the east. The Atlantic Puffin has a large population and a wide range. It is not considered endangered, but no decrease in the number. On land, has the typical upright posture of a Alcidae. At sea, swim on the surface and feed mainly on small fish, which trap diving into the water using their wings for propulsion.

GAVIOTAS Adult gulls have the head, neck, tail and lower body of a pure white, while the back and the back of the wings are pale gray, which gives the Spanish name herring gull . In Catalunya is known as "Gavia argentat", "gavotte" in Galicia or "kaio" in Euskadi. In English it is known as "herring gull". Habitat Gulls are typically coastal marine species and coastal lakes and lagoons, and fly great distances. Feeding Gulls feeding of everything edible minimally any kind of marine animals, plants, insects, carrion, small birds (at attacking in flight), bird eggs (both from other species as their own), chickens, rats, etc. If their prey are still alive usually catch them with pick and drop them from the top until they die or opened. It is often possible to see the gulls in inland towns, distant from the coast, where they arrived following the course of rivers. His varied diet has shifted coastal populations to


areas where they had never seen before. These new tenants alter and even eradicate local populations of birds that rarely compete with a bird of this greed.

The aim of this study was to determine the impact of priority and emergency Persistent Organic Pollutants (POPs) in gull eggs of two species, the Burrow Larus argentatus and protected species, Larus audouinii. These two species share habitat in the Ebro Delta (Catalonia, Spain). The compounds studied are included or planned in the Stockholm Convention and understand the dibenzo-p-dioxins and furans PCBs and PCDD / Fs dioxin were also detected in all samples. The widespread global presence of POPs is discussed in terms of eating habits, ecology of birds and anthropogenic pressures in the area of protected rearing of the Ebro Delta.
