It’s September, in a short time the Herons will be hard to find. At this point we should be photographing as many as we can.
The birds in this series are not the same. One of these will likely move a few miles down river and stay here for the winter. The other two will go south.
Comparing birds the last one, photo above, would be my choice as to who stays.
The largest Blue Herons are in New England. The bigger the bird the more likely they are to stay here for the winter.
I read that on the internet so it must be true.
