What is Totals?

"Totals" is the sum of all observations of a species from all checklists submitted within a specified date range and region. For example, a total of 885 Ospreys during the week of 15 April indicates the peak spring migration of the species when many congregate at coastal migration points. In contrast, a total of 67 Ospreys during the week starting 1 November indicates that many have left North America for more southerly wintering grounds.
