Week 13 rather like 11 and 12 I'm afraid - limited time to go and see what the owls are up to, but this week I've only seen one owl once - and I've managed to drive (or run) by four or five times.
I still think the female is sitting on eggs and the male is banished for a while but I guess I could be wrong and one of the owls has been killed.
I doubt it though - maybe if I feel a little better this week and the weather does improve - I'll get to spend a little more time watching these birds after work and see if I am correct about the hen sitting on eggs in the box.
Remember - a very good 24/7 live little owl cam can be found here - the last time I looked at this (Dutch) site, the hen was still sitting on three white eggs, virtually all day and all night...
