I have a camera box at my school. We had the beginnings of a beautiful nest and a pair frequently visiting. Today I have seen birds disturbing the nest, taking out sections of the twigs and feathers. Most recently the bird has been splaying their wings out, sitting low and wiggling about all around the box. I was wondering is this a new pair who are trying to leave their 'mark'. ? Separately the camera angle is slightly off - would is disrupt the birds hugely to move it at this time of year? Thanks :)
