Tubakuro means swallow in Japanese.

The Swallow made the nest for the first time at the entrance of my house. I was not interested in animals at all, but it has become interesting when I look at it for a while. I became able to understand the individuality of the swallows and be able to identify individuals. They have intelligence and sociality beyond my imagination. I think that it is not simply habits or instincts. But there is no swallow image on this site. (At the time of writing) The reason is next.

1st group: Children were eaten by the crow.

2nd group: Children were eaten by snakes.

3rd group: A snake has eaten a parent bird.

4th group: The crow broke the nest.

5th group: The sparrow was attacked by the nest.

It is very difficult for Swallow to become an adult safely. I am disappointed, but this is natural. I hope to succeed in safely next time.

It is also difficult to make wonderful software. However, I have gradually developed the "Cutting Planner" little by little. Swallows are positive though they have a hard time. I learned the swallows and made a shop name TubakuroSoft.
