媒体文件注释
One of seven females seen with 23 young - likely the offspring of all 7 females seen, this female is likely the "brood mother" that either "stole" the other fledglings or incubated all the eggs in a confined "dumping nest" (possibly a hollowed log or stump that would keep the eggs from spreading out too far) where the "community" females all laid their eggs (possible if necessary due to limited suitable nesting locations in a high water year).

Seven adult females, one with a "mega-brood" of 23 young (see uploaded photo).
