Blue Tit Nest Box Update

As of today there are 4 surviving chicks from the original 10 eggs. The mortality rate seems a bit high although chicks dying is inevitable and one of the reasons blue tits and other small short lived birds lay so many eggs. Watching other nest box cameras it seems quite a few nests have failed or produced few young this year. I don’t know enough to say why for sure but it could be related to the exceptionally warm March bringing the bugs out early and the subsequent cold snap killing them off.

The 4 chicks are getting the full attention of both parents who are doing a good job keeping the nest clean and feeding the chicks. Chicks that have died have been quickly removed. The parents are managing to find at least some of the green caterpillars essential for successful blue tit rearing as you can see from this picture taken today.

More updates soon, fledging should be around 21 days after hatching so 8th June or thereabouts.
