On June 19, we celebrated Cleo's birthday!

June is Akira's birthday month! Akira's exact birthday is unknown, but is estimated to have been born in June 1976. He turned 50 this year. He's the same age as Ai and Mari, and they've spent many years together.

The other day, we introduced some of the chimpanzees' "spring treats." This time, we would like to share their "rainy season treats."

Amid the various sounds of nature in Inuyama, "new sound" began to be heard around the time of the COVID-19 pandemic. It came from Ayumu, a chimpanzee, performing a display using wooden boards.

The Institute for the Evolutionary Origins of Human Behavior, where our activities are based, is located in Inuyama . The Inuyama Campus, is surrounded by rich natural environments. Throughout the year, the campus is filled with the sounds of nature, and if you listen carefully, you can hear the calls of many different bird species.

April 24 was Ayumu's birthday!

Gon (male, estimated to have been born in 1966)

After a long, bitterly cold winter, we've finally been enjoying many warm days from March into April. The cherry blossoms around the institute quickly came into full bloom—and just as quickly fell. In the gentle spring sunshine, the chimpanzees look very content.

Gon is the oldest chimpanzee at the EHUB. Born in 1966, he turns 60 this year. In Japan, the 60th birthday is a special occasion called kanreki.

春の訪れを感じさせるように、所内では本日、桃の花が咲きました。チンパンジーのアイを想い、記憶をつなぐメモリアルブログが始まります。その最初のバトンを受け取ってくださったのは、卒業生の山梨 裕美さんです。ぜひ、ご一読ください。

One month has passed since the chimpanzee Ai left us. In response to the many heartfelt messages we have received, we have created this memorial website in her honor. On this site, you can look back on her life and journey, view photographs, learn about her contributions to research, and read messages from those who cared for her.
