Description 100% natural materials: Our hummingbird house uses natural hibiscus grass to create a natural shape that easily blends in with the surrounding natural environment. Dry, durable, not easy to deformation, for birds to provide a natural, comfortable, safe habitat. 100% Hand woven: Our hanging nests are hand-woven from natural materials to look and feel natural, and each one is unique. The grass is so densely woven that it does not come off easily. Each measure of the house is 4.7 inches. The hole diameter is 2.1IN. This is a comfortable place for the birds to rest Bird safe House: Small birdhouses provide birds with a safe place to hide from predators. The spherical design makes the nest stronger. The perfect 2 IN front opening does not allow large predators such as raccoons, hawks or kites to enter your little friend's safe room. The perfect design: Rough surfaces can increase the friction of the bird's paw and make standing more stable. The outdoor hanging bird house is beautiful in appearance, not only ventilated, heat dissipation, rain proof, but also wide at the bottom, with enough space for activities. The hole design of the round hole makes it easier for birds to get in and also to hide from squirrels. A wide range of uses: Our aviaries can be hung in gardens, balconies, porches, tree trunks, offices or anywhere else you want to hang them outside or inside. In summer, they can drain the rain. You can also add hay to the nest when the temperature drops.
