观察细节
I don't have the exact count from that day, but 70 is a very conservative. We had a few months of huge numbers of Pine Siskins that spring. High, but reasonably conservative max counts through the seasons were roughly 200 on this date up to 450 later in the season. This was a day when Rod Bodkin was able to come over to join us along with his sound recorder device. He also had an external mic (I think), but I don't have the details about the device and mic.
