Mother and Calf Humpback Whales (Amami Oshima)

奄美大島ホエールスイム Humback Whale Swim in AMAMI OSHIMA (5)

This is a report of the Amami Oshima Whale Watching Tour from early March.

Every year from January to March, the Humpback Whales, which spend their summers of Kamchatka-Aleutian Islands, will spend their winter months in Amami Oshima for breeding. Most of them head south to the Kerama Islands of Okinawa, but whales some stay near the Amami Islands. There, you might be able to encounter mother whales as they are nursing young whales or the male escort whales that will chase after the females in a ‘heat run.’

On this tour, we had some inclement weather so we could only go out to see for 3 of the 5 days. Despite the short time observing, we could manage to see a ‘heat run’ from the boat, as well as see the mother and calf plus an escorting male whale in the water. The calf was about a year old and very active.

In the morning hours, we couldn’t encounter any whales, but during the afternoon, we were told “There is a wonderful mother and calf out here now” and we rushed to the area. As soon as we could, we were in the water and the pair appeared right in front of us. It is really amazing to see them in person.

The frolicking yearling calf. It was active, doing tail slaps and pectoral fin slaps at the surface of the water.

This mother whale was very tolerant and with the escort whale watches the calf very closely. Even when the people were close to her calf. This mother must have experience raising her calves and has perhaps gotten used to humans, too.

The calf also swam in circles around its mother, showing us its belly. One day, this calf will grow up and leave the Amami Oshima area, moving north as it sets out independently by that time.

This one shot of the three whales together was a stunning highlight for the day!
Perhaps you are wondering what we did when we couldn’t get out to sea? We went for nature walks in the virgin forests of Kinsakubara, did some birdwatching, explored mangroves by canoe, and searched for the endemic Amami rabbit (Pentalagus furnessi). We could enjoy a full tour of all the beautiful natural areas the Amami Islands has to offer!
