Gözlem detayları
Flying southward in wave after wave. 14 were seen on the water, others in the air. Typical groups ranged from a low of 10-20, to many at 30-45, and several at 55-70. Estimated at least 1000 on site. Looking at photo sequence carefully, at least 1600 photographed over five minutes of a six minute sequence, after eliminating any apparent redundancies. Photographed in each minute from 10:59-12:05: 346, 224, 458, 374, 85, 0 (no photos), 170. I had seen several groups fly by before starting to photograph--too difficult to count at distance--so count is likely higher.
