Long-tailed tit (エナガ) with cocoon

On February 24, 2018, a long-tailed tit (エナガ) struggled to remove insect cocoon material from the left side of its head, neck, and wing. I was able to take a sequence of photographs as the bird rubbed itself against a branch.

Eventually the bird managed to remove the material. It was quite an accomplishment without hands.
