Another seasonal summary of the totals of many species observed and tallied by our technician at the Waterbird Watch is here. The technician was on duty six hours per day, six days per week, from March 1 to May 21 in the spring season. 

In addition to the "Top Ten" listed below, other noteworthy sightings included 54 American Avocets, Whimbrel and Marbled Godwit, 8 Red-necked Grebes, 1 Western Grebe, and 341 Red-throated Loons.  Note that the numbers of Red-breasted Mergansers and Double-crested Cormorants were lower than in many previous seasons. The advantage of datasets collected over a long time period allows us to see trends in the data.
