Build a nestbox (deluxe) for jackdaws

VERY IMPORTANT UPDATE:
Change the entrance hole of the jackdaw nest box to a round 90 mm opening instead of a square 120 mm opening. This greatly increases the chances of survival. Owls are less likely to enter the nest box, and the young birds are less likely to be pushed out by a sibling when sitting in the entrance.

This is the design to create a nest box for jackdaws with a camera. The whole design is deluxe!
This means, the nest box is a bit larger for increased comfort for the birds. The nest box is also more sturdy, and it is very easy to clean.
The camera used in the design is a cheap, but pretty good camera!
