As the process of human urbanization continues to accelerate, more and more animals need to make a living in reinforced concrete cities, and survival of the fittest has become the law of animal survival. Researchers have found that the crowned parrot (also known as the cockatoo) living in Sydney, Australia, has mastered the ability to forage from the garbage can.
When lunch time came, the crowned parrot, which lived in Sydney, Australia, began to forage. The lidded bin doesn't make it hard at all.
This is the footage taken by researchers at the Max Planck Institute for Animal Behavior. They have been studying parrots in Sydney city in recent years, and they have invited residents to assist in investigating whether parrots have been found to be opening dumpsters. Prior to 2018, only three districts reported the detection of parrots with such behavior, and by the end of 2019, that number had increased to 44 districts. This shows that urban parrots will learn from each other, and more and more parrots will open garbage bins to forage.
The study also found that 84 percent of "unboxed" parrots were males, and parrots with "unboxing" skills had a higher status and a wider social range in the flock. There are more parrots in the middle stage of learning "unboxing" skills, and some parrots can constantly update their skills during the learning process and find ways to save effort and use better.
The researchers say the findings could help people understand how animals adapt to urbanization and why some species are more resilient to urban life.
