The birds started coming back to the new birdhouse on October 12th. There seems to have been a competition for who gets to stay over night (at one point the scale detected two birds inside the birdhouse :-) ). You can also see the battery lose a few milli volts during the night. This is due to the new LIR2032 coin cell that powers the electronics. It only has a capacity of about 40 mAh compared to the 100 mAh LiPo pack used previously. I'm curious to see if the LIR2032 is enough to get the birdhouse through the winter (I can always put in the old battery if needed).

Update: I just passed the birdhouse on my way home. There was a flock of about half a dozen young birds hopping around the birdhouse flying in and out. I'm no bird expert but maybe there was a realtor there trying to auction off the place (these little guys always make me smile :-) ).
