In April they started to make their nest. Related to the blog is the following;
Past a few weeks, swallows have been keeping in their nest alternately and overly chirping.
I thought they have laid eggs and my thought was right!
One day I found their egg-shell on the balcony.
It seems the #swallows have #laid #eggs safely.— Madam-Fujiko@followback🇯🇵 (@Madam_Fujiko) May 5, 2020

In Japan it is said that swallow’s nest brings good fortune.
It is also said that when they lay eggs, the first eggshell leaves for a person who lives in the house in order to inform that they lay eggs safely by showing their first eggshells.
That’s lovely signal 🙂
