Over the next few months, we all traveled to the area to investigate the Reed Parrotbill, on average once a month, for at least 30 minutes each investigation, and recorded the first discovered way and the number of the Reed Parrotbill each time. We used a Nikon D6 camera (600X) to record this phenomenon.
