This is an oval bird's nest primarily made from natural materials. I found it while pruning branches from trees in my yard. The birds have already fledged, and it's no longer in use. Since a brown-eared bulbul often visited the tree, it may have been a bulbul's nest. - Materials: Natural materials (palm bark, tree bark, black mulch, cotton, vinyl string, etc.) - Shape: Oval nest - Size: Outer diameter approximately 12.5 x 13.5 cm, inner diameter approximately 7 x 9 cm, height approximately 8 cm - Uses: Bird's nest, gardening, etc. It has some minor soiling due to being a natural item. I will take care in packaging, but it may be fragile. Please understand this before purchasing.
