Лазоревка, Blue Tit, Parus coeruleus

Filmed over 22 days showing Blue Tit chicks from hatching to 22 days later when they fledge. Each day is recorded with a brief 20sec or so clip to show the change to the chicks over time. I used a DV cam fitted inside a nest box with illumination from white LEDs. See the tech page on my site here for full details
