观察细节
[Kellen: It started with one bird roosting in a tree towards the Hadley Gardens, which was super weird for this neighborhood setting, but then that bird led us to a few more in the adjacent trees. Before we knew it, some 50-60 Black-crowned Night Herons were flying all over the place, calling a lot. Most of the birds did re-settle in the trees of the area. We did later find a creek running through the neighborhood, which might partially help to explain their numbers here.]
