That's right, sneezing can confirm breeding. Yesterday I visited Baldwin Creek to see if I could confirm breeding for a pair of GREEN HERONS. Atlasers had seen a pair repeatedly visiting the extensive willow patch near the creek mouth earlier in the season, but there was no further indication they were nesting. After walking under the canopy and inspecting the many stick structures high above, most built by woodrats, I came across one about the right size and shape for a heron. This was the most promising nest out of dozens of candidates, but unfortunately the nest appeared unoccupied. At that point I had been on the hunt for a while now and was considering what to do next. A breeze blew through the trees and I couldn't resist the urge to sneeze. ACHOO, and the head of a wary heron rose out of the nest above me! When the heron shifted its position I could see downy nestlings through gaps in the nest bowl. Breeding confirmed.
