Japanese White Eye
The Mejiro or, Zosterops japonicus, rarely stops moving.
This time of year they are buzzing around everywhere, especially near cherry blossoms.
Up north, for a visit to Mt.Yaedake, there were few blossoms in bloom.
So, I pulled up this series of the bird photos, taken JAN 9, 2015, in my back yard.
Camera: Pentax K3
