What has happened so far in Nesting Box #1

Nest building was engaged with much vigor during the last week.



I had the impression that in addition to the standard diligent Sparrow which has been working on the nest, another Sparrow examined the nest a couple of time. As already posted on the 19th of March, I believed it to be a female, but I am not so sure anymore...

Yesterday it rained quite heavily. Strangely enough, the nesting box is not visited as much on weekends. The Eurasian Tree Sparrow did pay one visit though despite it being a Saturday, and despite the heavy rain. In the video below (in which I believe the Sparrow is giving another display), one can tell that the bird is quite wet.
