Bird nesting box with roof as a drinking spot for medium sized bird species

This bird house is designed for medium sized or larger bird species, such as jackdaws, goldeneye ducks, possibly even owls or kestrels. I decided to go this way since I felt that there simply are not that many bird boxes available of such dimensions meant for these larger birds of sort. This product also features a drinking spot on the top of the box, which is simultaneously a roof of the box, which can be easily removed. This makes cleaning very convenient. The side faces of the roof are transparent to put emphasis on the form of the whole object meanwhile it enables anyone to see how much water is remaining in the reservoir.
