February 4-18 is the beginning of Spring, Risshun (立春) in the traditional Japanese calendar of 24 seasons. The middle micro-season in Risshun, Kōō kenkan su (黄鶯睍睆), is February 9-13. Here are some photographs of birds and flowers that I took February 11-13 during Kōō kenkan su in 2020.
On February 11 I rode my mountain bike across Yasugawa and up Oyamakawa through Mikami and Omifuji and then to the Omifuji Botanical Gardens in Kitazakura, Yasu City (map).
On February 12 I walked around my neighborhood and then down to a nearby river, Yasugawa (野洲川). I spent most of my time looking at scenery.
