I used to watch a friends one over the summer. It was so exciting to see a bird arrive and take such diligent care of the space and her eggs. (The males appear to be mostly useless but some did return regularly with worms etc).

It led me to cancel Netflix because I was enjoying the nest cam more.

Edit: here’s a great one of a blue tit. They’ll be gone by the end of the summer, I think: https://webcam.sanslogic.co.uk/?top

Thanks for the recommendations. I’m not as interested in the big predators for whatever reason but there are some nice suggestions.
