Water bird is the most. Interesting facts about birds

This article discusses the fastest living beings living in the water. At first glance, it seems that representatives water World Even closely will not be able to compete at speeds with the rapid inhabitants of sushi and birds. After all, the habitat itself is water, dense and viscous, does not predispose to move at a very high speed. But it turned out that if the fastest "Letunov", the aquatic animals still "did not reach", then the Earth representatives of the fauna in speed, practically, are not inferior. It is clear that the speed for them is one of the most important qualities that allow them to survive in wildlifeAllowing the "hunter" to focus "sacrifice", and the "victim" escape from the "hunter". But what maximum speed Are able to develop the inhabitants of the seas, oceans and fresh reservoirs? Consider the fastest of them ...

Tiger shark (lat. GaleoCerdo Cuvier) - 53 km / h

Tiger shark It has a big mouth in which there are a lot of teeth with beveled vertices. Such a mouth is adapted for nutrition with sea turtles. Turtle speed is about 35 km / h, and the speed of the tiger shark is 53 km / h. Why does she need such a big speed supply? Probably, then so that it is not to become the prey of larger predators.



Kitka (Lat. Orcinus ORCA) - 55 km / h.
At the picture of Kosykaki off the coast of Alaska

Kotaka - Marine mammal, kitto-shaped detachment, beloved whales, Dolphin family. The only surviving modern representative of the kind of kota. This is the largest water predator that, nevertheless, develops a good speed - 55 km / h. As in the previous case, such a speed of Kosyk is needed exclusively for hunting, because no one except for a person attacks this animal. High speed quality and considerable intelligence make Kojawka very fast and dangerous predator.



Atlantic Tarpon (Megalops Atlanticus) - 56 km / h

Tarpon - Large fish, similar to externally on herring, but not having nothing in common with it. Atlantic Tarpon (Megalops Atlanticus) can grow up to 2 meters in length, and its speed corresponds to its size - up to 56 km / h. Interestingly, when this fish lacks oxygen, they can jump out of the water to literally, block air.



Blonde Sea Pig (Phocoenoides Dalli) - 56 km / h

White sea pig, or sea pig dala - mammal, reaching a length of 1.8-2 meters, and a newborn individual - 1 m. The males have characteristic signs that distinguish them from females (hump in front of the tail part, beveled front and others). Live blonde guinea pigs groups (about 20 individuals). They can sail at a speed of a little more than 56 km / h. Sea pigs - predators. Feed on fish and ciphat mollusks, on which they hunt at night.



Blue, or Blue Shark (Prionace Glauca) - 69 km / h

Blue, or Blue Shark - type of cartilage fish from the gray shark family. Widespread all over the world and lives both in the ocean and the speculation, and is one of the most common sharks on Earth. It has an elongated torso, with elongated pectoral fins. It is quite large in size and can reach the length of 4 meters. The name of this shark corresponds to its colors (blue back and blue belly). The rate that this sufficiently common subtropical shark is capable of developing - 65-69 km / h.



Yolkoper Tuna (Thunnus albacares) - 70 km / h

Yellow truck tuna - Fish from the Skumbrian family, which plays a significant role in the fishing industry. It is found in all the tropical and temperate latitudes of world oceans, but is absent in the Mediterranean. It has impressive for commercial fish with dimensions - 2-2.5 meters in length, and the weight reaches 200 kg. Its grayish body cross is about 20 longitudinal white-yellow lines. These large fish are capable of sailing at speeds up to 70 km / h.



Atlantic Blue Tuna (Thunnus Thynnus) - 74 km / h

Atlantic blue tuna - One of the fastest fish. It can develop speed up to 74 km / h. Blue tuna got its name due to its color: the back of a blue-gray, bluish color, and belly - silver. These fish are warm, which is quite rare of fish. Thanks to this, the fish feel well in cold, and in warm waters.



Mackerel (Scomber) - 77 km / h

Few people know that such common fishing fish like mackerel (Scomber), can develop a very greater speed. During spawning or in a throw, it can be saved from speed up to 70-77 km / h. Interestingly, mackerel is held by large groups in which all the fish of one value.



Marlin (Lat. Makaira) - 80 km / h.
In the picture of Indo-Pacific Blue Marlin

Marlini From the family of sailfish in the length of the body can be compared with some kind of sharks, as they can grow up to 4 m, but at the speed of MARLIN movement significantly overtake the shark, and many other aquatic inhabitants. These fish can race with a speed of 80 km / h. Interestingly, it was for Marlin who hunted the hero of the story "Old Man and the Sea" (E.Hhemaniway).



Fish Sailboat (Istiophorus Platypterus) - 109 km / h

The fastest fish also applies to the Marlinov family. Fish sailboat He fell into the Guinness Book of Records due to the incredible speed, which is capable of developing. The fish has a characteristic spinal fin in the form of a sail, which has given the name. When sailboats float at high speed, the dorsal, anal and abdominal fins are folded and removed into special recesses on the body of the fish. The sailboat is an active predator and can develop speed up to 100 km / h. During a series of tests conducted in the Long-Ki fishing camp, Florida, USA, a sailboat sailed 91 m for 3 s, which is equal to the speed of 109 km / h.

Many feathers confidently feel not only in the air sphere, but also on the water. This is a habitat, a stern base. Determine what birds are waterfowl,it is possible on the basis of the study of the feathery, their abilities to be held on the surface. They are not related species, but have a lot general damn: interfallated membrane, thick plumage, spanking gland.

Between themselves waterfowl Do not form food competition, it is different in different ways, specialize in their feeds. Each species occupies its ecological niche. There are no herbivore varieties among them. Birds are either adjacent to predators, or - to omnivorous courts.

Waterfowl Birds are represented by detachments:

  • horse-shaped;
  • gagaro-shaped;
  • rude-shaped;
  • pelican-like;
  • penguin-like;
  • caravel;
  • rzhanko-shaped.

Representatives of the Guseum-like family in full composition lead water or semi-water life. All the membrane is located on three fingers, the beak of the flattened shape, the plate on the sidelines of the language to filter food. In Russia, the types of goose and duck subsamples live.

Screams of Gagars are widely known, similar to loud laughter.

With the danger of birds, they do not take off, but dive, folding the wings on the back from wetting. Special metering core gland covered feathers of waterfowl birds, Provides water protection.

Blackcover (polar) Gagar

Bird sizes are the largest among conifers. Characteristic differences in the dark green color of the head and the shape of the beak resembling the dagger. In the cold time flying to the sea with warm waters. In flights moving with multiple groups. Couples of Garagas are saved for life. Live birds about 20 years old.

Paddykova – great Family of waterfowl, comprising 22 species. The name arose based on the food perception of their peculiar meat with an unpleasant smell of fish. Family representatives are often taken for ducks, but there are many differences between them.

They are excellent divers due to strong short legs that do not have a membrane between your fingers, but are equipped with side blades for rowing.

Chomga (big leafing)

Birds dwell on ponds, lakes, love cane thickets. Do not meet on land, she even takes off after running from the water. The neck retains white color all year ahead. Food fasteners and invertebrate organisms. Floats with deep immersion in water.

Black-hungry grinding

The size is inferior to Chomge. Body length up to 35 cm, weight up to 600 grams. It is found on shallow reservoirs with thickets of plants in Europe, Africa, in the west of the United States. With the cooling of the birds from the northern zones fly to the southern reservoirs. In lead a settling life.

According to the name of the neck and head, black, on the ears - yellow beams of feathers. On the sides of red feathers, belly white. The main sign is bloody-red eyes. In chicks - red spots between the eyes and the keyboard.

Small grinding

The most minor representative among relatives in size. The mass of only 150-370 g, the length of the wing is approximately 100 mm. Dark, with brown tint top, belly dirty and white. Need ahead of the chestnut color. On the wings white mirror. Yellow eyes, with reddish riders.

Mounts in small lakes and rivers with slow flow. Unlike ducks that warm frozen legs in the animals of the abdomen, the leafing raise them over the water to the sides.

Pelican-shaped (weak) representatives of the family are distinguished by a swimming pool between all four fingers. Feet-oars and long wings to many allow you to confidently swim and fly, but they are awkward. Birds distinguishes a lot in the appearance and lifestyle.

Cormorant

Bird of large sizes, up to 1 m long, weighing 2-3 kg, the span of the wings is about 160 cm. Black and blue plumage with a whiten stain on the throat, disappearing by winter. Powerful hooked beak.

Curly pelican

Swirling feathers on the forehead, head, cervals give a bird a unique shaggy appearance. Paws of dark gray. The length of the body is up to 180 cm, the scope of the wings is over 3 m, the mass is 8-13 kg.

Public bird forms colonies. In the hunt, they act collectively: they surround the shoals and cotton wings on the water ride the fish in the place where it is easier to catch. Curly and pink pelicans - rare waterfowl of Russiamade in red. Nest on the Caspian coast, shores Azov Sea.

Pink Pelican.

The name reflects a gentle shade of a plumage that is intensified on the abdominal side. Flying feathers of black color are clearly visible in the flight. Required powerful waters of waterfowl, up to 46 cm long.

Pink hunt for large prey: Karpov, Cichlid. During the day in food one bird needs 1-1.2 kg of fish.

Voznesensky frigate

It dwells on the islands of the Atlantic Ocean. The plumage of large birds is black, head - with green tump. Crown bag of red. Feature is the catching fish.

Penguin-shaped representatives or penguins- Fluttering seabirds of 18 species, but perfectly floating and diving. The streamlined form of tel is ideal for moving in water. Evolution turned the wings of birds in fins. The average velocity of the Penguins in water is 10 km / h.

Powerful muscles and tight bone coster provide them with confident stay in the seabed. Color, like many sea inhabitants, camouflage: gray-blue spin, with black sampling, white belly.

Inhabit the medium of harsh climatic conditions. Anatomically, they are adapted to the extreme exposure to cold. The heat insulation provides a layer of fat, up to 3 cm, three-layer waterproof feathers. Internal blood flow is designed in such a way that heat loss is minimized. One colony of birds includes several thousand individuals.

Crane-shaped birds are one of the first ever lost the ability to fly. Many species are common in continents except zones and. Sorodi differ significantly by type, sizes. There are crumbs from 20 cm and birds-giants up to 2 m.

Sunny Heron

It dwells in the tropical areas of America next to the water bodies: wetlands, lakes, bays.

The motley plumage of gray-brown shades, with the addition of yellow-green, white, black tones. The size is up to 53 cm, the weight on average 200-220 g. Long neck in the area of \u200b\u200bthe throat of white color. Feet orange, long. Fan tail with horizontal stripes of dark color. The mined facilities of nutrition (frogs, fish, casuals) of the Heronwicks in water before use.

Aram (shepherd crane)

It dwells in the territories of the American continent, overgrown with vegetation near the swamps with fresh water. Fly badly, they are trying to run away from dangers.

The loud screams they publish serve as a means of protection. Crane body length up to 60 cm, weight no more than 1 kg, and wings with an average of 1 m. Bird feeds are extracted from the bottom of the reservoir - snails, mussels, reptiles. There are frogs and insects in the diet.

Sterry (White Crane)

Large bird With the scope of the wings of about 2.3 m, weighing an average of 7-8 kg, a height of up to 140 cm. The beak in length is greater than that of other caravals, red. White plumage, except for black flying feathers. Legs are long.

The nesting of the Sterchs is exclusively in Russia. Favorite places finds in a deserted Yakut tundra or on the fake acquisitions. In winter, birds migrate to India, Iran, China.

The feature of the sterch - in strong attachment to the reservoirs. All of their structure is aimed at movement in viscous soil. The swords will never feed on agricultural land, people are sideways. Beautiful and rare bird threatened.

African Lapchaton

The name reflects the area of \u200b\u200bbirds - the rivers and lakes of African mainland, south of Sahara and Ethiopia. The peculiarity of the laptic thinner in deep immersion during a swim, in which only the head and neck are visible. In danger, it can run through water with short takeoffs and descents.

The length of the bird is about 28-30 cm. The color is green and brown on top, white on the trouser. On the sides of the head pass two white stripes.

Lyshuha (water chicken)

Small birdsimilar to normal duck, but a homogeneous black color with a white spot on her head. Missed the bright leathery record reminds Lysin as the corresponding name generated.

A short beak is similar to chicken. Yellowish paws with long fingers of gray. Everywhere distributed in Europe, Kazakhstan, Central Asia, North Africa. Prefers shallow water, thickets of cane, sources, reeds. Black waterfowl -object of fishing.

Rzhanko-shaped water birds are represented by many species, different in size, lifestyle. Attachment to water bodies and anatomical features bring these feathered.

Sea Chaika

Among the relatives are distinguished by large sizes: the weight is about 2 kg, the body length is 75 cm, the wingspan of 160-170 cm. The plumage is predominantly white color, except for the upper feathers of black on the wings. The flight speed is 90-110 km / h.

Kuliki-Soroka

Contrast plumage of black and white gamma. Paws, beak bright orange- red, the same shade circles around the eyes. Couples-Soroki are common in sea coasts, except for polar zones. The beak is long, adapted for breaking on marine mining stones.

Serpeclow

They are found in Central Asia, in Altai groups along the rocky rivers in the mountainous regions. For them, it is important for the presence of islets for nesting. Often hunts in shallow water. A notable beak of the red abnormal shape helps to look for production between the stones at the bottom of the reservoirs.

Floating

Small birds conducting a significant part of the water. Perfectly swim, but do not dive. Feed food from the surface or immersing the head as a duck, under water for hunting. Stay like floats, with high fit. Mostly found in the tundra reservoirs.

Water lifestyle combined birds able to stay on the surface. This unbreakable link fills their way of life with a special content. Waterfowl birds in the photo Reflect the harmony of the air and water sphere of nature.

Most birds bathers, cleaning the operenim. Swallows, haircuts and crags several times in a row plunge into water on the fly. Other birds, standing or squeezing on shallow water, shake fluffy feathers, trying to evenly moisten them. Some forest species bathe in rain water or dew accumulated on the leaves. Felling feathered, flowing and shaking feathers, cleaning them with a beak and flapping with wings.

Birds lubricate themselves with fat, which highlights the cuxoic iron at the base of the tail. They bring him a beak on feathers, thereby making them water-repellent and more elastic. To lubricate the punching of the head, the birds with the help of the beak rubbing the fat, and then scratch their heads.

Salted salt water

Seagulls drink salt sea water, because their glands are adapted to filter salt.

It can swim, but can not fly: Penguin is the only bird that can swim, but can not fly. In addition, it is the only bird walking.

The most frost-resistant: the less afraid of the cold duck and geese. They withstand temperatures up to -110 ° C, while white bears and seals are only up to -80 ° C. The imperial penguin can take out a cold to 60 degrees C.

Penguins feathers grow uniformly. Only a few bird feathers grow uniformly throughout the body; These are usually non-flying species, such as Penguins.

Penguins strengthen their eggs. During the layout of the eggs of female penguins, a significant number of shells of mollusks and mussels are swallowed. Thus, penguins receive additional calcium, which is necessary in order for the eggs to be stronger. Fortified eggs are more likely to not crash solid surfacesWhat is possible during the penguins fights when they throw eggs to each other are 43% of cases of egg destruction.

In principle, mollusks and males are swallowed with shells, but females absorb much more.

Fish odd smell. It is experimentally proven that, for example, large naval birds in stupid and petrels feel the smell of fish for three kilometers. But Albatrosse feel the smell of bait (slice of Sala) Already in thirty kilometers!

Ducks are chemically attracting sprayes

And one more curious observation. Spring group of wild ducks shoodled nostrils. And the spleen immediately ceased to show interest in females. It is believed that females of ducks allocate some chemicals attracting males.

Breathing without nostrils. Most birds nostrils lead in nasal cavities at the base of the beak. However, Baklanov, Olush and some other types of nostrils are absent, and they are forced to breathe mouth. Air, hitting in the nostril or mouth, is sent to the larynx, from which trachea begins.

What legs to walk on water? Birds, walking in shallow water, such as herons and stilt, are peculiar to long legs. For birds that walk on carpets from floating leaves and quags are characterized by long fingers and claws, so as not to fall. Penguins have short and thick legs are far behind the center of gravity. For this reason, they can walk, only holding the body vertically, short chains. If you need to move faster, they fall on the belly and slide, as on the sleigh, pushing out from the snow with lastoid wings and legs.

The best diver. Penguins are found at a depth of 10 - 20 meters from the surface of the ocean. Every hour he spends at a depth of 5 to 40 minutes or more at depth. The Imperial Penguin (Aptenodytes Forsteri) is able to dive to a depth of more than 200 m. The greatest depth of immersion among birds was recorded in 1990 in the Sea of \u200b\u200bRoss, off the coast of Antarctica. One of the imperial penguins (dived at the depth of 483 m).

What makes penguins at a depth of one and a half kilometer? Japanese biologists set cameras on the backs of animals, which for a long time spend in naval depths. As the authors of the project explains, the sun's rays penetrate only 150 meters deep into the ocean, so it is still unknown that they are doing in a semi-kilometer depth, for example, imperial penguins or marine elephants that can be immersed by one and a half kilometers.

Penguins are found at a depth of 10 - 20 meters from the surface of the ocean. Every hour he spends at a depth of 5 to 40 minutes or more at depth. The Imperial Penguin (Aptenodytes Forsteri) is able to dive to a depth of more than 200 m. The greatest depth of immersion among birds was recorded in 1990 in the Sea of \u200b\u200bRoss, off the coast of Antarctica. One of the imperial penguins (dived at the depth of 483 m).

Can swim three weeks. Patagonian penguin can swim for two or three weeks and cover the distance to 1500 km.

The fastest swimmer. Papuan Penguin (Pygoscelis Papua) can be saved at a speed of up to 27 km / h.

Like birds swim

Birds are floating due to alternate rowing of legs, usually equipped with membranes or blades on the fingers acting as oars. A wide torso provides waterflinking birds stability, and their dense feathered cover contains air that increases buoyancy. The ability to swim, as a rule, is necessary to bird-producing birds. Swans, geese and some ducks in shallow water practicing incomplete diving: turning the tail up and pulling the neck down, they get feed from the bottom.

Dive into water from height

Olushi (Sulidae), pelicans, paints and other fishing species are pricted in water since the summer, and the height of the fall depends on the size of the bird and the depths they seek to achieve. So, heavy flares, falling a stone from a height of 30 m, immersed in water for 3-3.6 m. Adjustable crags dive with a smaller height and plunge just a few centimeters.

Dive from water surface

Penguins, Gagars Gavia Immer, Radiers, Clangula Hyemalis ducks and many other birds dive from the surface of the water. Without having inertia of divers divers, they use to immerse the movement of their feet and (or) wings. These species of the legs are usually located at the rear end of the body, like a screw under the veil from the ship. When immersed, they can reduce buoyancy, tightly pressing feathers and squeezing air bags.

Seagulls who know how to swim under water

Clear (Alcidae) - typical seabirds, relatives of gulls and pieces, have learned to swim perfectly under water and dive. Ability to quickly adapt to water conditions Life led to active speciation - they are most diverse and numerous in northern pacifik, there are currently 23 types of 11 types of birth. For cleaner birds, a belief-like shape of the body is characterized, dense feathers, a short tail, refigble paws and relatively narrow wings, folding in the likeness of cheerful when diving.

Excellent divers

Probably, for most birds, the limit diving depth from the surface of the water is close to 6 m. However, the black-free polar gagar GAVIA IMMER can be immersed by 18 m, and the vacant duck of the club Clangula Hyemalis  is approximately 60 m.

The most evil penguin

Stone penguins are distinguished by a very angry character, crypt and aggressive.

Stool shoots predator with liquid content of his stomach

Northern Bird-Stormy is able to shoot a predator with a liquid content of his stomach. Stormy usually feeds on fish, do not disdain and the waste left after the sealing carcass, and therefore it is not surprising that a thick mass with a filrowable smell of fish oil accumulates in his stomach. Observations held recently showed that the bird with great accuracy shoots a mall mass at a distance of up to two meters. The chick and he already has the skill of a sniper. Their weapons are stupid used mainly against painting birds. The fat "spit", falling into the owl, seagull or crows, long brings the bird in order - gluits feathers. A getting predator cannot fly or swim, and sometimes even dies from the cold - after all, clean, loose feathers create good thermal insulation around the body.

Global climate warming on the planet cut the nutrient diet sea birds

After a sudden climate change in 1977, when water in the Bering Sea and the adjacent Bay of Alaska was in the winter above the norm on 2 degrees, the change in the well-established rhythm of seabirds began. While the population of the crab has practically not changed, the population of the large and rich variety of fish is greatly injured - Mallotus Villosus, as well as cod. This temperature change could be an important factor for recession of the number of seabirds. For example, to achieve the same population number, seabirds should almost double the diet of the fish, which is so lacking on those that are.

Where colonial birds nest

The main place in Primorye, where sea colonial birds nest are nesting, this is the Bay of Peter the Great, located in the extreme south of the edge. The area of \u200b\u200bits water area is about 55600 sq. Km. Numerous rocky islands, up to 200 m high and a rugged coastline with shallow coves, create good conditions For nesting and feeding numerous seabirds. About 100,000 colonial birds nests here; The most numerous of them is a black-eyed seagull. Petra Great Bay - the only nesting place of two representatives of the Tube-Loaded Tubes - Wilo-Vilo-Kachrope Oceanodroma and Pongogol Petrel Calonectris Leucomelas. In addition, there is a reason to believe that the rarest bird nests here - a crochet old man.

In the Gulf of Peter the Great annually winter 100,000-200000 water birds: Cayra, Kanyow-Baby, Pacific and Siza Seagulls, Barring Bablan and different kinds marine ducks.

What depends on the growth of seabird populations

The prosperity of populations does not always depends on the feed base, since the abundance of feed does not always mean its availability. The impressive number of seabirds is the result of a series of successful seasons, when the weather, and nature contributed to the successful breeding and survival of birds. Small differences in the dates of the destruction of ice cover, temperature or salinity of water can lead to noticeable vibrations of the number of seabirds. Moreover, climatic quirks of recent years have led some populations of seabirds face of disappearance.

The number of bird colonies of the Sea of \u200b\u200bOkhotsk

The length of the continental coast of the Okhotsk Sea is about 8.6 thousand km. And island - up to 1.7 thousand km. On the rocky sections of the coast found at least 600 colonies of seabirds total number About 12.8 million with Bay. Most of them are about 9.5 million ° or 75% - timed to the original part of the Okhotsk Sea: Yamsk Archipelago (7.5 million), Shalikhov Bay (0.75 million), on Lan (1.3 million), coast and islands of Tuoulian lips (0.05 million) . Bird bazaars consist in the OCN from the birds of the family of cleansing: (97%), as well as tubes (silly, swing), weary (cormorants), gulls (Maew. Pacific seagull).

Pacific seagulls pulled out vegetation on the island

On the Pacific island can nest from 350 to 500 thousand pairs of chap. In the afternoon, the bird's feed is searched to fly into the sea for many tens of kilometers, and in the evening, returning to the island, arrange a spectacular rosium in the sky. Deep twilight is circling over the island of tens of thousands of birds, fascinating the look by the synchronicity of movement and the suddenness of his change. This giant flock will be a ball, it twists the harness, then suddenly hesitates to the sea or sits down to the rocks. This vocabulary is settled among the stony shots, forming dense multi-storey colonies.

Seagulls are born from Cambals

In Kamchatka, there is another kind of river chap, about which the ITELEN claims that they are born from Cambals. This seagull builds himself a nest on land and puts two eggs; From one as if Kambala goes out, from the other - a seagull.

Self-size with an eagle

The storm is similar to ordinary river seagulls, but such copies come across among them, which are not at all inferior to the largest eagle or Gus. They have a big yellowish beak beak, big, like owls, eyes, and the color of their plumage is dark brown with white spots all over the body.

Heads the weather

The conferens are considered a heavy sin to kill sea forty, because it leads as if it seems to change the weather that immediately flies. The bird, called Pica Marina Gallorum - French Sea, is often found in the summer at sea and on the rivers of Kamchatka and Sakhalin.

Sea birds destroy the reserve

Baklanam's real war was announced in the Reserve "Circassium" located on the shore of the Sea of \u200b\u200bAzov in the Zaporizhia region. The flocks of these seemingly innocent birds flew here with the Danube in the 90s - in the smoothies of the river, people created them unbearable conditions. The Islands of the Sea and found themselves to the bird of the ideal place for habitat.

Today, the colony in the reserve has more than 20 thousand cormorants, and each bird eats a kilogram of fish a day. As a result, the fish stocks of the Sea of \u200b\u200bAzov per day are reduced by 20 tons, and the cormorant eats fishery fish - bull and pike perch. The formation of the cormorant turned into another trouble: the reserve was covered with a layer of litter, a poisonous for trees, with difficulty grown three decades back on the square in 40 hectares. On the recommendation of scientists, the hugers destroy the nests and scare cormorants to force the birds to fly to another place.

Sea birds spread radiation

The excrement of seabirds can enter radioactive isotopes in the food chains. In moderate latitudes, the risk of such pollution is small, but on the nearest approaches to the Arctic, it can be much more. It is there that guano - bird litter - is the main source of nutrients for plants, which are then eaten by animals.

Samples of excrement of seabirds, taken in two extensive colonies, 10 times more radioactive than all other samples of the soil. Pobiles eat contaminated fish and crustaceans, and isotopes are concentrated in feces. The excess of nutrients in them encourages the growth of plants, and the latter concentrate radioactive substances thus. And this is a serious problem - because plants enter the diet of many animals, especially reindeer.

Radioactive materials fall into oceans as a result of natural geological processes occurring at the seabed. Contributes to human activity. In the Arctic, for example - in the Kara Sea - there is a warehouse of radioactive waste, radioactive substances fall into the sea as a result of atmospheric tests of nuclear weapons of accidents on nuclear facilities.
