So, at the time the BNOW fledglings are no for a longer period returning to the cavity and it is vacant for a though - which is what typically and sooner or later takes place - I will go up there and install a new digicam (the 1 that’s there is Really old), In the meantime, the cavity is remaining partially "lit up" by the infrared LED’s from the PTZ cam, so that is why you can still see a minor little bit there at evening.
