Wilnest Contego
The Wilnest Contego is the second birdhouse which was designed and engineered by GBO for Widee. The house has an inner housing which provides extra insulation and which can be rotated to choose from two different entrance holes. This way the user can decide which type of bird will nest in the birdhouse.
The Contego has a ventilation system which prevents the formation of condensation and drains surplus moisture. The overhanging roof prevents the penetration of direct sunlight
