The photo is taken by and must be credited to Joe Motohashi. Link to National Geogprahic site, where I found it, is in the image- just click on it. The bird is also known as Mejiro in Japan. I really like the delicate composition.
Quote from National Geographic Wesbsite:
It was a warm day in spite of being early March, and I went out to photograph birds in Tokyo’s Zenpukuji Park,” says Your Shot member Joe Motohashi, whose photo was featured in the Daily Dozen. “There was one early blooming cherry tree there. And I found a couple of Japanese white-eyes going to it. It seemed to symbolize the coming of spring.”
