I finally got a small "deposit" from our fine feathered friends, so I decided it was time to add the bird spikes. This required relocating the Solar and UV sensors such that the spikes don't cast shadows on these sensors. Consequently the ISS sensors were unplugged while working on this and there was some erroneous temperature, dew point (hum), Solar and UV readings this morning. Rain gauge was not affected because I unplugged it prior to the maintenance.
