RESULTS
The first discovery of Reed Parrotbill entering Smooth Cordgrass was at
noon in November 2021, we heard the Reed Parrotbill chirping in Smooth
Cordgrass. After we stopped moving and stood still for a while, we saw
the Reed Parrotbill flocking and singing in Smooth Cordgrass (See
Fig.2.). In the grass, there were many Reed Parrotbills jumping inside
the Smooth Cordgrass, grasping the middle and upper parts of the Smooth
Cordgrass, and moves horizontally
along the Smooth Cordgrass. From November 2021 to March 2022, throughout
the overwintering period, we investigated five times, and found that the
Reed Parrotbill was active in Smooth Cordgrass each time (See Table.1.).
