Day 10 - you wouldn't believe how big the babies are now
Without showing you pictures or video it's very difficult to describe just how quickly the new babies are growing. However, I hope to have a much better quality camera fitted next time around so you will be able to see high-definition video live on the Internet showing the blue tits throughout the whole breeding process.
The babies have now opened their eyes as far as I can tell and they all have a substantial amount of downy feather growth. There are still four babies as five of the eggs failed to hatch. Both female and male are in an out of the box all day long feeding the babies on what appear to be small caterpillars.
The male or the female will often put a caterpillar in the mouth of the baby and then wait for the baby to produce a sack of faeces which they then take out of the box and dispose of. Strangely, this is my favourite part of the feeding. It's lovely to see them stick their little backsides in the air and produce this huge turd. Mind you, the female was swallowing the faeces when they first hatched, I think there are a little bit too big to swallow now.
I would imagine that in a weeks time these babies are going to be well on the way and I don't suppose will be very long before they fledge, not at the rate they are growing at.
Come back for more updates in a few days time
