Construction Continues...(at Great Tit's Disappointment ?)

The Eurasian Tree Sparrow again spent considerable time yesterday constructing the nest. I have not counted yet, but it appears that it has made more than 10 visits during the day, and not just in the morning, but also in the afternoon. This is in fact the first time it has visited the nesting box after the midday hours.
Funnily enough, a Great Tit visited the nest in the afternoon (no Great Tits had been in the nesting box since the weekend). The bird appears puzzled at first. Indeed the nest has changed a great deal since Sunday!

Unfortunately, the sound cable was not properly plugged in so I had no audio yesterday. I have posted a video sequence of a number of yesterday's visits. You can however tell from the video that the both birds did a "mini" display (not comparable to the ones I posted on the weekend).
