Notes:
- An unusually high number of Sabine's Gulls pushed through the interior this month, beginning in the second week of September. Although September is the month they're most expect inland, this was a banner event, with many states breaking high count records for the species. As expected in the interior, almost all were juveniles. Similarly, excellent numbers were recorded offshore in California (mixed ages with adults being the majority). Apparently, this was due to a wonderful coincidence of observer's being present at feeding sites during offshore pelagic trips, and seems to be unrelated to the event that took place inland.
