觀察細節
***Rare, but numerous this year due to irruption. Continuing flock, first heard a couple minutes after I arrived. I counted around 20 birds, then 52 after a few smaller flocks merged into one. Later found a group of an additional 20 birds. For the most part the birds stayed at the tops of trees, coming down to eye level a few times. The flocks were found around the parking lot, the green building, and the fields between the parking lot and river.
