Notas sobre o média
Leading edge of the kettle where some Broad-winged Hawks were starting to stream out headed NE. The clicking that is heard is Kathleen clicking the hand tally counter as the birds were streaming out of kettles.
Detalhes da observação
Kathleen counted birds streaming out of kettles 1x1 using a hand tally counter. All were headed SW until 1:35 pm after which the direction of movement flipped 180 degrees to NE. The total count of 1,824 for this checklist is based on the birds moving NE assuming that the 658 birds flying SW earlier in the day were included in the birds headed NE in the afternoon. SW Movement: First kettle of 17 going SW at 9:09 am. Last kettle of 21 going SW at 1:35 pm. Total of 658 birds headed SW. NE Movement: First kettle of roughly 470 birds going NE at 1:47 pm. Last kettle of 42 going NE at 3:04 pm, then a few smaller groups of 1 to 4 until the end of the checklist. Total of 1,824 going NE.
