Hooray! Our video equipped nest box has seen some frantic nest building activity today!

(sorry about the black and white image, it was getting dark when I grabbed this picture)
Lets just hope she (or is it the guys who start the nest building to say “look what a great provider I will be!” to the gals?) lays some eggs and has some chicks… 😀

Doesn’t it happen the other way round? Have the chicks first, the result being eggs ❓
I’ll get my coat :zip:
Blue tit? Pretty sure it’s a penguin…
