Reactive birds: opened surprising fact about penguins
They migrate vast distances, although this is not necessary.

Thick-billed penguins are able to overcome 80 km per day, scientists of the University of Otago in New Zealand.
Researchers have attached satellite trackers to ten males and seven females of these species crested penguin, to follow the behavior of birds from November to March. The results were impressive. They are published in the journal PLOS One.
Scientists managed to establish that by growing Chicks, thick-billed penguins begin to migrate from New Zealand to the South-West. Some of them should be South of Tasmania, which is located in the subtropical zone and the other in the subantarctic zone. In these places the penguins restore power, hard eating, and then migrate back.
Birds live at such an incredible rate for 10 weeks and overcome during this time, the distance from 3.5 to 6.8 thousand kilometers. Rather, it is the maximum distance that can move the penguins, the researchers say.
Birds migrate when the ocean is rich food that seems meaningless. Scientists believe that this extraordinary behavior may be a vestige inherited from the penguins who lived in subantarctic environments not yet migrated to New Zealand.
This “inheritance” explains the fact that the thick-billed penguins only live in the South of New Zealand. If they were gnezdovoi to the North, then migrate in the subantarctic zone would have been much harder or even impossible.
