Siberian Stonechat,ノビタキ

 IUCN Red List： least concern species

At least in the past autumn, when it comes October you could observe Siberian stonechat anywhere in the countryside of this area. However, in this year I could observe them only three birds until today. I wonder what is the cause of less migrating in to here? It is seen the same in the other migrating birds.

(The color of the feathers of Siberian Stonechat has been already become the color of the like these images around the end of September when the breeding season ends and come flies here.)
