Observation details

CLR counted 98 in one flyover flock and a roosting group of 323 (both 1x1 counts); together, this totals a minimum of 421. However, a much larger roosting flock was conservatively estimated by Tyler Williams to contain ~450 individuals (estimated by 50s), to which we added the first ~100. The real number may have been well into the 600s. Upon further review of the photo archived below, I added another 100 birds to this tally, as I could count ~525 birds in this photo alone, which I believe excludes even more Franklin's Gulls farther to the right.
