Ravens can be as clever as chimps
London : An international team of researchers has found that despite having much smaller brains ravens are as clever as chimpanzees.
The findings indicate that rather than the brain size, neuronal density and structure of the birds’ brains play an important role vis-a-vis their intelligence.
“Absolute brain size is not the whole story. We found that corvid birds performed as well as the great apes, despite having much smaller brains,” said Can Kabadayi, doctoral student at Lund University in Sweden.
Intelligence is difficult to test, but one aspect of being clever is inhibitory control, and the ability to override animal impulses and choose a more rational behaviour.
The team analysed ravens, jackdaws and New Caledonian crows to better understand their inhibitory control.
The performance of the jackdaws and the crows came very close to 100 percent, comparable to a performance by bonobos and gorillas.
“This shows that bird brains are quite efficient, despite having a smaller absolute brain size. As indicated by the study, there might be other factors apart from absolute brain size that are important for intelligence, such as neuronal density,” Kabadayi explained.
The team first trained the birds to obtain a treat in an opaque tube with a hole at each end. Then they repeated the test with a transparent tube.
The animal impulse would naturally be to go straight for the tube as they saw the food.
However, all of the ravens chose to enter the tube from the ends in every try.
“There is still so much we need to understand and learn about the relationship between intelligence and brain size, as well as the structure of a bird’s brain. But this study clearly shows that bird brains are not simply birdbrains after all,” the researchers concluded.
Lucknow: Vishal Singh, a renowned social worker from Lucknow, also known as Foodman, has once again made India proud. He was honored by the Happy Hands Gloves Cooperative Limited Company in Korathai, Thailand, for his work with the Hunger Free World Mission.
The Hunger Free World Mission’s meeting was held in Korathai, Thailand, under Vishal Singh’s leadership.

He said the mission is not just about feeding people but also about meeting other basic needs of those who are struggling. The mission focuses on helping families of terminally ill patients in hospitals by providing food and shelter. It also works to fulfill essential needs like education, jobs, and care for the elderly.
For the last 16 years, the Vijay Sri Foundation has been providing free services, benefiting thousands of people. Vishal Singh highlighted that the mission aims to gain global recognition like other organizations such as WHO, WWF, and Red Cross, which work for social causes.
During this meeting, Vishal Singh was appointed as the Chairman of the Hunger Free World Mission by representatives from various countries. They also discussed holding regular meetings in different countries to push the mission forward.
Business tycoon Dr. Abhishek Verma has also supported this humanitarian mission, vowing to promote the idea of “Seva Parmo Dharma” (Service is the highest duty) worldwide. Vishal Singh praised him, stating that people like Dr .Abhishek Verma inspire others to work for the betterment of society.
Recently, Romania’s Ambassador, Mr . Daniela Sezonov Ţane, invited Vishal Singh to the Romanian Embassy in Delhi, where they discussed the mission in detail. Impressed by his humanitarian work, she honored Vishal Singh and invited him to Romania to take the mission forward .
Food man Vishal Singh has been serving the people of India for the past 16 years. Through the Vijay Sri Foundation, he provides free meals to cancer patients & their families ,shelter, and education for women & children along with running free old-age homes in Lucknow.

During the COVID-19 pandemic, Vishal Singh and his team worked tirelessly to provide food and help to the needy, including starving children, elderly citizens, and pregnant women. Despite contracting the virus himself, he continued to assist others after his recovery. He even created a life-saving oxygen regulator using household items, which was praised by doctors both in India and abroad.
In his address at the meeting, Vishal Singh spoke about his mission to create a hunger-free world. He pointed out that India’s large population, along with issues like unemployment and poverty, has caused the country to fall on the Hunger Index. He urged people to contribute just one handful of grains daily to help create a hunger-free world.
He concluded by saying that through social participation, we can empower the people around us, meet their basic needs, and work together to build a stronger, more prosperous, and developed society.
