Seagulls are close animals in the eyes of people. We often see seagulls on certain sailboats. Who knew seagulls were the invisible killers of the ocean? A man has made a surprising discovery off the coast of Argentina's Valdez Peninsula. A seagull flies over a whale then lands.
Everything seemed as ordinary as a bird landing on a crocodile. Both parties are quite harmonious in a symbiotic relationship, but not the seagull. Oceanographers discovered that their actions attacked the whale, especially the one breathing on the surface.
When the seagull lands on the whale's skin, it begins to dig up the skin from the whale's back with its beak. The photo shows a southern right whale. The skin and fat on its back are favored by seagulls.
When southern right whales emerge from the water to breathe, seagulls fly in groups. Some female whales and the gameSouthern right whales are often selected by seagulls. According to statistics from American oceanographers, about 99% of whales have varying degrees of back injuries. Comparison of the tracks revealed that these injuries were caused by seagulls, which frantically tore the skin from the whale's back, leaving bruises all over its body.
Many coastal towns consider seagulls to be a bad species. Research has shown that seagulls attack whales that breathe on the water's surface, and more and more large marine mammals are suffering huge back injuries from seagull attacks. This southern right whale was attacked by a seagull. Researchers fear this could lead to abnormal deaths of large marine mammals.
In fact, seagulls have never learned to attack whales since ancient times. This phenomenon was discovered in the yearss 1970. This is the first time that seagulls learned to get what they need from the backs of southern right whales. This kind of situation has gotten worse in recent years, and everyone seems to have learned it.
Note: Pay attention to the wound outlined in red. I was pecked by a seagull and the wound was quite large.
Seagulls often hunt whales. They will observe the movements of the whales in the air. Once the whales emerge from the water, they fly away. The skin and fat are the gulls' favorites. Between the 1970s and 2011, oceanographers at the University of Utah in Salt Lake City found that the number of whales attacked increased from 2% to 99%, with almost all whales attacked by seagulls, a level unprecedented.
Note on photo: Some of the whales were covered in bruises and had holes drilled into their backs.
When the skina whale is damaged, this can lead to dehydration and thermoregulation problems. Gulls on the Argentinian coast of the Valdez Peninsula are even more aggressive, calling their mates to attack the whales. Seagulls have previously been found pecking out the eyes of baby seals before killing them, and the babies then die in excruciating pain.
Seagulls fly in the sky and ships sail on the sea.
Ships sailing on the sea are usually accompanied by a group of white seagulls, which adds infinite vitality and poetry to the endless white ocean.
One of the reasons is that when a ship sails on the sea, an upward airflow is generated on the ship due to the resistance of air and sea water .Seagull behind or behind the boatTows square and can be easily supported when flying through rising air currents.
And when they get tired, they can stop at any corner of the ship to rest.
The second reason is that in the vast ocean, the waves of the wave breaker stir up small fish, shrimp, etc. They were stunned and floating on the water. The foresighted seagulls will soon spot them. Eat it. This “keep the rabbit and wait for the rabbit” foraging is definitely a smart move on the part of the seagulls.
Seagull (scientific name: Laruscanus): It is a medium-sized seabird of the Aves class and the Larus family. Weight 394 to 586 grams; body length 451 to 510 mm. The lifespan is 24 years.
Summer feathers of adult birds: white head and neck, slate gray back and shoulders; the wing coverts are also slate gray, the same color as the waist, the tail coverts and tail feathers are pure; white.
Primary flight feathers have white tipshes and large white mirrors.
In winter, fine brown lines are scattered on the head and neck, and sometimes black on the tip of the mouth.
Iris**; mouth, feet and toes light green**.
