Where are the migratory birds？

As it has become to mid-September if it is the same as in the past migrant birds should be seen.

However, it cannot be seen especially Muscicapidae this year yet, except this eastern buzzard.

I have been thinking that what brings its cause must be high temperature during this summer.
