Birds also make funerals

When jays detect the corpses, they will stop searching for prey and call other animals to the scene.

Teresa Iglesias, a scientist at the University of California in the US, and colleagues put together many things - such as wooden toys, jagged corpses, and effigies of owls - in courtyards in residential areas and observing counter The application of jays to them, the BBC reported.

The reaction of jays is not the same when they see wooden objects. But when they saw the corpses, they shouted loudly to let the others fly. Then the jays stood around the corpse and continued to shout loudly to call out the others.

On that day, the jays stopped looking for food. This behavior lasts until the next day.

When the birds see the owl-shaped toys - the species catch them to eat - they also gather in one place and make an alarm. Then the whole group seeks to scare away the owl.

'The presence of jays and owls are all information that jays want to share with their fellow humans to raise awareness of the dangers in their environment. Thanks to that communication mechanism, they can protect each other, reduce the risk of death , 'the team concluded.

Many animals also have the habit of calling other animals when they discover the same type. For example, elephants and giraffes often gather around the corpses in the herd. Biologists think that they have the concept of life and death, so whenever a member of the herd dies, they gather around the body to show their regret.
