In tune with the micro seasons

Just last night I wrote about the start of the 13th micro season of the year known as "Swallows Return". At the time I didn't have a photo of swallows so I initially used a photo of yaezakura, late blooming cherry blossoms, to depict the changes in nature during this micro season.

I have since updated the photo for that post, because just today I saw swallows dozens of times. And I was lucky that they didn't fly away when I got relatively close and I was able to get some photos of them. I think ever since I started learning about the micro seasons, I am even more in tune with the changes in nature. 

Have you seen any swallows yet this year? Do you notice the micro changes in nature?
