The tall Gentleman`s house for birds: tall with a thatch roof with natural finish. A Great Tit favorite. Tips: Clean your birdhouses each fall with a brush and warm water - to prevent the build-up of parasites. Hang your bird house at least 6 feet of the ground and 30 feet (10 meters) from other similar bird houses. Don`t expose them to full sun - preferaby hang them on the north side of your tree. Dimensions: 20.5 x 15.5 x 30 cm
