A female Blue Tit builds her nest inside a nestbox. Filmed with 2 cameras using motion detecting software from i-Catcher the female can be seen building her nest over a number of days compressed down to just 21/2 mins of video.
Using motion detection has the effect of speeding up the action so you can see the nest develope and grow as the nest enters differant stages of building and lining out.
All this is set to background music of Sabre Dance.
