There are many unafraid birds on the streets of Sydney, swaying along the streets.
Looking for food everywhere, people come and do not hide, at most leisurely pace to both sides.
The lack of basic awe for humans at the top of the food chain is the impression that the Impressions have on the birds as a whole.
But when I saw this kind of bird, what I was thinking was:
Brother, don't come over here. I'll give you all my food.
It is large, with a pointed beak, and has long been seen in the vicinity of various garbage bins.
That's the famous junk bird.
White ibis, 's scientific name is Egret. Everyone calls it a junk bird, because they always stand on dirty trash cans, looking for the rest of mankind's food.
But these big birds, which seem to adapt to urban life and enjoy junk food, are actually "country birds."
They originally lived in swamps and wetlands in western New York, but began to migrate gradually from their original habitat to the city since 1970.
Why? Because the garbage in the city is so delicious?
Yeah. The rubbish is really delicious.
But the huge birds, which were supposed to live in remote suburbs, migrated to the city in piles, allegedly because of drought caused by the extraction of water for irrigation and the loss of their original habitat.
According to statistics, nearly 1 / 4 trash birds now live in Sydney, a big city.
Before 1970, the figure was 0. 5%.
Come to the big city, the living environment has changed, can they still live on?
But geese, these big birds are really good at survival.
Originally in remote wetlands, they lived on insects, earthworms and crustaceans such as prawns.
In short, their eating habits are mainly meat-eating, and these foods are rich in protein.
But coming to the city means they can't live entirely on this kind of food.
As a result, they quickly found a new kind of food-fast food and junk food, the piles of garbage cans.
Whether it's bread, fries, hamburgers, spaghetti, pizza or biscuits, they find whatever they eat.
These foods contain large amounts of carbohydrates and fats, which are completely absent in their previous habitat.
Often eat these food that originally does not belong to their digestive system, can their body be able to bear?
The answer. The experts are not quite sure.
But on the face of it, the egret lives well, growing steadily, and continues to multiply.
We don't have a good impression of junk birds because they always pick up garbage around the trash can and look dirty.
But after close contact with the birds, the researchers said they were surprised to find that the birds were not only smart and courageous, but also cute.
They are very good character, very funny, although also can quarrel with other birds, but still very docile.
In the future, these tough big birds will appear more and more around the garbage can in the city, even in your hands of the delicious covetous.
Next up, boys, be ready to "live in harmony" with more egrets.
