What is this bird?

Today's bird.
Today’s bird.
   The ume(梅) are blooming beautifully in my garden now. Of course, mejiro are coming almost everyday. This morning, I found another kind bird. What is this? I cannot remember. I think this is its song because the song came from the same direction of the bird.

Edit:
   One of my Japanese Blog visitors told me the name of the bird. It is a Shijūkara(四十雀). I’ve already seen it, I think. Now, my head is cleared. (^^)

   Thanks a lot, りりさん.
