Looking at the dash board I noticed that the weight of the little bird sometimes drops a couple of grams during the night (please see the  image below). I am guessing this happens because the little bird leans up to the wall of the birdhouse and by doing so takes one foot off the weight scale. For the next version of the birdhouse I would like the scale to be wall to wall. And I would also like to move the electronics, solar panel and antenna into a single enclosure on top of the roof. This should simplify the setup and give the birds more room on the inside.
