虎鶫 The earliest record of White's Thrush

私のいつも散策する森でトラツグミの羽毛を拾いました。

Large and Tip is black, the characteristic White's Thrush feather. 

On October 14th, I found a feather of White's Thrush in my patch. November 25（in 2019）was the earliest record about White's Thrush in my bird census and trail camera surveys before the record of this day, but it has been updated.

The feather taught me that it is important to use various research methods to know bird life and nature.
