Blue tits and nest box

As our daughter has been off school on her Spring holidays I have not been back to Easthill Park since the snow. As it was a sunny day I thought I would go and see if there was anything interesting about. There were the usual birds around, both visible or noticeable by their calls. The checked out the bird box near the entrance to the park but did not notice any activity.


However, a pair of blue tits have taken up residence in another box. It took a while to be sure that they were activily using the box, rather than just checking it out.


A blue tit returning to the nest box would take a very round about way of getting to the box (not wanting to give away the location of its nest site to possible predators). At the last moment it would dart in through the hole. When leaving the box the blue tits left quickly, again not wanting to attract attention. Apart from one time during the 30 minutes I watched them, only one bird was in the box at a time. The blue tit outside the box also chased off any other blue tits that came too close.
