Hummingbird Houses

The basic structure is fine, and appealing, but the little branch comes wadded up and can't be made to look anything like the picture, there are no instructions, and the little wire screen to hold in the cotton is covered in sharp points. But keep looking; those enclosed houses aren't right for hummingbirds. This works fine if you file the corners of the mesh and use pliers to wire the branch to the house, but have low expectations. Hummingbirds also won't bother if it isn't 10 to 30 feet above the ground without obstructions Infront of it and at least 20 feet from their food source (check my Googling on that).
