The smallest bird in Europe is also the smallest bird in Japan.
There were 3 of them in the trees next to the river today, presumably just arrived from across the Tsugaru Straits this morning. I also saw my first Bullheaded Shrike of the year and yesterday got my first Red-flanked Bluetail of 2020 too.
Goldcrest is the smallest ? – Well, I never… thought it must be Wren or something.
Wren is slightly bigger than Goldcrest, no?
