Sorry, just reporting this now, and it should be amusing when I try to enter the data on eBird. Friday afternoon/evening (the 15th) between 7:15 and 8:15sh PM, Jeff Webb and I saw 19 flyover BLACK-CROWNED NIGHT HERONS from the Spring Point trail that runs through the SMCC campus. We both had binoculars, it was still quite bright and sunny out, all the birds were very identifiable, and some could be heard calling ("kwok"). A couple flew by themselves but most were in small flocks of 3-5.
Almost all were heading from the direction of Peaks and Greater Diamond Island, and flying overhead in a southwesterly direction, toward inland from our vantage point. Only one pair flew in the opposite direction, toward the islands. None landed on the shore near SMCC, as a few often do when evening approaches. I think it's safe to say that none of these birds were repeat flyovers, either, as the way these small groups were flying was very direct and linear... not milling around as gulls, for example would. Additionally none of our counts for adults to subadults matched for any of the flocks that went over.
There were also 43 Common Eider ducklings seen with adults in the same vicinity, not far offshore.
