Nest Structures for Ducks and Geese

Giant Canada Geese
Tree Structures


Tree structures are simply post structures that are modified for mounting in trees (Figure 4). Their advantages are that they can be used where water levels rise dramatically, can be inconspicuous if desired, and the trees provide stable supports. The disadvantages are that they are not predator proof, they may be difficult to maintain, and hawks and owls may compete for the nest sites with the geese. When placed on trees over water, the structures should be mounted 3 to 4 feet above the maximum anticipated high water level. When placed over land, they should be mounted 6 to 20 feet above the ground or 3 to 4 feet above flood stage.
