We moved house last year and there were a couple of bird boxes already in place. One on a south facing wall and one on a sheltered west facing wall. We put a camera in the S facing box but I have since read that S facing is not the best position. The W facing box has a couple of birds (wrens?) that fly in at dusk each night. I assume they leave during the day and I think they were nesting in there last year. Will it disturb them and cause them to leave if we move the camera to this box now? If we move the other box to this wall too how far apart would they need to be? Unfortunately there is no N or E facing wall we can use. Thank you for any advice you can give me.
