"Tubakuro" means swallow in Japanese.

Around 2011, swallows made a nest for the first time at the front door. I was not interested in animals at all, but it became interesting when I was watching for a while. During my observation, I came to understand the individuality of each of the swallows. I came to be able to identify individuals to some extent by means of gestures. The swallows have more intelligence than I had ever imagined. The swallows have a strong bond. And it seems that there is sociality. But,

  • First pair: Swallow's baby was eaten by a crow immediately after hatching.

  • Second pair: Swallow's baby was eaten by the snake a few days after hatching.

  • Third pair: An adult swallow was eaten by a snake before laying eggs.

  • Fourth pair: The nest was broken by a crow.

  • Fifth pair: The swallow was attacked by sparrows. Swallow brought about 10 friends from the neighborhood but lost.

It does not go well well. The swallows are disappointing because they seem to look really fun until the incident happens. But that would be the natural world. Please do not make a nest at home anymore. Although I think so, I still expect it in the future.

Software production soon got stuck, but developed little by little. The name is "TubakuroSoft" in honor of swallows who live positively while having a hard time.

Cutting Planner may seem expensive. You can purchase after free trial for 30 days. We believe that this software can contribute to society.

We sometimes receive reports from customers such as "errors" and "does not work properly". Emails from customers will make Cutting Planner more reliable. Thank you very much.

Later I learned how to protect the swallow from crows, snakes and sparrows. For the first time on June 15, 2013, three swallows flew off from the nest.
