Did you know there are over 50 species of birds in North America that will nest in gourds? But not just any gourd. Each bird has its own requirement for entrance hole size and gourd size. The following chart provides a list of birds and their preferred gourd size.
It is highly recommended to make your birdhouse using an organically grown gourd. Gourds grown using pesticides and chemicals can actually absorb those chemicals into the gourd wall and cause damage to birds. Welburn Gourd Farm grows all their gourds organically.
In the chart on right, gourd size is listed by the diameter (in inches), which is the distance straight across at the widest point of the gourd (not the circumference, which is the distance all the way around the gourd).
Our Box of 6 Birdhouse Gourds are 5-6.9 inches in diameter. Our Birdhouse gourds are pre-drilled, with a cord for hanging already threaded and installed.
