Nest-building of Long-tailed tit,エナガの巣作り

As in many wild birds in Japan, Long-tailed tit will start making nests for breeding in March.

Long-tailed tit is one of them, and here they have already started making nests.

However, in the case of this wild bird, it makes a nest that is quite different from other birds.

I learned that material of nesting is spider thread, moss, small wooden skin etc, paste spider's thread on the twigs of the crotch of the tree facing upwards and add moss and others to complete a round bag-shaped nest.

I have taken pictures of wild birds for a long time, this was the first time that I saw this scene.

 Is it around two-thirds completion?
