Yellow Apple Gourd Birdhouse. These are actually crafted from what is called an apple gourd. The shape of the gourd resembles an actual apple. The sizes will vary, but we use those that most resembles an actual apple. Some are taller and some are more round than others (average width is 5 to 8 inches and 5 to 9 inches in height). The opening is predrilled 1 1/8" in diameter and typically attracts wrens for nesting. The bottom is drilled with drainage holes. Apples are strung with wire for hanging in your choice location. Colors are applied with acrylics and each birdhouse is coated with a polyurethene finish. Includes silk leaf. We offer various apple varieties with appropriate shading (i.e. red delicious, yellow, granny smith). Specify Color: Red, yellow, green
