Bird's nest is smart

In the Blue Bird world, smart drums are more likely to find partners than other guys.

Jason Keagy, a scientist from the University of Maryland (USA) studied the double activity of the green patties (Ptilonorhynchus violaceus) in Australia. This bird is famous for its complex flirtatious behavior. Their team is also considered a masterpiece of nature. The drums decorate the nest with colorful objects. The female bird visits the team to choose a mate.

" Green patties are birds that make people bode for their intelligence and skill ," Keagy told the BBC.

Keagy's group wanted to find out if the male bird's intelligence played an important role in the female partner's selection process. Before that, they thought that smart drums were more likely to win the hearts of 'girls'. Scientists designed a number of special games to assess the ability to solve the difficulties and creativity of the blue-green patties. Then they marked the smart ones.

The follow-up process showed that those of the " smart " group always succeed in pairing. Meanwhile the success rate in the ' not smart' group is significantly lower. Even many males do not have partners during the breeding season.

Keagy thinks there are a number of reasons why females want to choose drums to solve problems.Smart children are usually healthy. Many previous studies have shown that those infected with parasites and parasites are often unwise and have a weak immune system .

' Of course, females don't want their children to inherit bad genes from sick males ,' Keagy said.

In addition, in birds where both parents take care of their children, smart drums always find food faster. They also take care of young birds better than other male birds.

Experts do not know how the female birds find the smart drums. But according to Keagy they have two basic ways. First, they monitor the drums' actions during courtship. When they want to attract the attention of females, the males often dance, mimic the actions of other children and build their nests. The female looks at those actions to assess the level of intelligence of the male.

Another possibility is that males use intelligence to seduce or hold the female in the nest. ' It is possible that many males know how to apply both ways to enjoy the love of the female, ' Keagy commented.
