Juvenile Nankeen night heron in flight
It seems strange to see these birds flying around during the day but when they get disturbed by people walking near their roosting trees they swirl around above the trees for a while before settling down again. Bit silly, really, as they are hard to see in the trees until they take off. Also a bit silly to roost in trees right next to a path and parking area! This one is a juvenile with all the streaks, so 48J for Birds of Australia set.
