I have notice at night that the birds leave any Ideas why?
They go to a more natural roost. The nest is used for procreation; once the egg/s are laid the female remains with them until they hatch. The male will not be far away and provides all food to the female during this time and to her, and the chicks when they hatch, until they fledge. Right now they are cleaning up and repairing the nest. These 2 have been using this nest for many years and there was some concern the cam pole might move them from this nest.
