观察细节
Just after 11:00, while completing the loop around the wetland, we began to notice a large influx of Broad-winged Hawks flying overhead on a southerly bearing (we had seen one previously). As the BWHA's streamed over us, in a ribbon that often filled our scopes, we continually revised our estimate upwards. The overhead ribbon of BWHA's lasted for more than ten minutes, and the birds did not pass out of view for more than twenty minutes. Finally, we agreed upon an estimate of 6,000 birds. We would stress that this is a conservative estimate, and that there were likely more than this. We feel very privileged to have seen this awesome natural spectacle.
