After my first attempt at nest boxes (stryofoam computer packing material which the geese promply chewed up and ate!) I followed local tradition and placed auto tires in shaded areas I thought would make nice nests along with a pile of straw out in the sun. It gets hot here in NC. The ladies agreed with some of my locations and filled 'their' tires with straw and started nesting. I already knew that they carefully covered their nests before leaving. I had two big surprizes though, one goose liked roses or the protection offered by thorns and nested under a rose bush. The other disappeared and I thought she was dead but she had found a old clump of pampas grass in the front yard and nested there. For those of you that don't know about pampas grass it is tall and decorative, it adds its new growth around the outside of the clump and dies off in the center. when well aged the center space is plenty of room for a goose nest.
