Troyer Vertical Gourd Product Information |
Each PolyGourd is made of #2 Food-Grade Polyethylene (the same material your plastic milk bottles are made of). The walls are 3/16" thick which gives them a very high insulating value against the sun's heat (unlike the widely used aluminum houses that radiate the sun's heat directly into the nesting compartments and cause high mortality rates to eggs and baby birds). The Tunnel Gourd is 10" long X 8" wide which allows more room for the young birds to grow without being stacked on top of each other. In addition, there is a 4" tunnel attached to the front of the gourd that places the nesting compartment further from the entrance to keep predators from dragging birds out of the gourds. Also, because of the larger size, mature mating pairs lay an average of 7-8 eggs per nest instead of the usual 3-4 eggs in the standard 6" x 6" square condo compartments found on traditional multi-compartmented purple martin houses (we've even seen some gourds with as many as 11 eggs). There are vent holes on the bottom that allow air to flow up through the nesting material to keep the insides of our gourds cool and dry. In the southern states, you can drill out the vent holes at the top to keep the insides even cooler on those very hot summer days. The screw-off lid allows for easy clean-out and periodic routine inspections of the nesting compartment. Finally, Troyer Tunnel Gourds are set up with a built-in Sparrow Trap. |
Purple Martin Propagators sells the Vertical Troyer Gourd in case lot sizes of 12-gourds-per-case. Our case price is $240 (that's just $20 each). This price INCLUDES shipping and handling. The gourds ship directly from our Pennsylvania manufacturing facility to you and by-pass the middle-man. |
Purple Martin Propagators only sells SREH (Starling Resistant Entry Hole) instead of round-hole PolyGourds because the starling population here in the US has grown to such large numbers that now there isn't anywhere in the purple martin breeding range where they don't attack and kill adult as well as young purple martins in their nests. We want to ensure the housing systems we sell are the safest out there for the purple martins. |

When a sparrow starts to build a nest in your Tunnel Gourd, simply bring the housing system down, set the trap, raise the housing system back up, and, within a few minutes the sparrow will go back into the compartment and trip the trap. You can now rid yourself of this invasive bird, clean out their nest and open it back up for the purple martins to build and raise their young in. |
