This is a situation I did not anticipate. We have been spending the winter in Kauai. A few days ago I started getting notifications from our security camera. The notifications were frequent. My first thought was that there had been a snowstorm and the guys who clear our driveway were doing their job. They shovel off the deck. Examining the video this was not the case. There was nothing to see.
It took me a while to figure out what was going on. The light/camera has a microphone built in so I listened for a while. Eventually, I figured out what was going on. Birds were building a nest on top of the light fixture. There is also a speaker and a siren built in. I tried yelling at the birds which seemed to have no impact. I decided not to try the siren because I was concerned about freaking out the neighbors.
I removed the nest when we returned home. No eggs were in the nest so I moved the entire thing to a nearby tree assuming the birds were watching me.
