Gourd Oblong Hole Less Than 8
Product Model: NL10100
Gourd-Oblong Hole. Field tests have shown that purple martins will almost always choose the 11 in Natureline Plastic Gourd over any smaller natural or plastic gourds. Reports also indicate that there are larger numbers of eggs laid in large diameter gourds and that more nestlings survive to fledge from large nest cavities than from small nest cavities. Easy to clean. Easy-to-follow assembly instructions plus tips from a noted ornithologist on attracting purple martins are included with each gourd.
