今年も現れた。　It has appeared this year as well.

サンタではありません・・・。葉っぱの落ちた枝木の上で見えにくいかもしれませんが、小鳥の巣です。
おそらく、シジュウカラかゴジュウカラでしょう。
ほとんど毎年、家の近くに巣を作っている小鳥たちですが、今年は庭の柿木で子育てをしたようです。
カラスの攻撃から守るために？比較的人間の生活空間の近く、頭上2メートルくらいの位置にあります。
It is not Santa Claus, but a bird nest among the thing tree branches with no leaves, a little bit difficult to distinguish.
It may have been built by great tits or nuthatches. 
Almost every year the wild small birds build their nest near our house and the persimmon tree in our garden was their raising place this year.
It is only about 2 meters high above us, very close to our living place, maybe to protect themselves from crows.
