Heres another birdbox lookalike with another twist.
The finder will quickly realise the lid lifts clear as it's only held in place by magnets, that said they still can not get the inner cache out!
Of course they have brought a pencil with them that they can insert in the hole on the underside thus pushing up the inner section containing the container and getting a well earned smiley.
A waterproof container, logbook, pencil & screws are provided.
The entrance hole is only drilled half way through then painted black so no feathered friends can gain entry.
