Another Plastic Gourd Innovation
The Troyer Horizontal Plastic Gourd
This horizontal plastic gourd was
designed and developed by Andrew Troyer of Conneautville, Pa.
It features the crescent shaped entrance hole in the end of the
neck. Again, there is no prep to this gourd and is ready to
hang when it arrives at your purple martin site. As seen in the
photo, the Troyer Horizontal Gourd has just the right
proportions to allow the birds all the freedom to rear a full brood
of young with ease. And, the young in turn will have all the room
they need to stretch out.
Let's look at a few of the built in
features of this new plastic horizontal
The construction is one-piece, blow-molded with a 4"
diameter molded-in, threaded access port. The gourd is 14" long and
9" in diameter at the bulb. It has 4 - 5/16" drainage holes in
the bottom and having a one-piece body, there are no seams to
potentially leak. On top of the gourd is a molded in hanging port to
pass your wire through or a 3/8" diameter rod to hang it from.
Being horizontal, the neck now becomes the entrance for the birds
and contains a molded in Crescent shaped Starling Resistant Entrance
Hole with a built in 2" tall tail support for easy entry. In
the rear of the gourd are two small canopies under which the
landlord can drill two 3/8" diameter vent holes if he so
Being horizontal, the gourd possesses nearly 14" of depth
placing the birds well out of the reach of just about any climbing
As has been stated by just about every authority on
purple martins, the color of any purple martin housing should be
white. The Troyer Horizontal Gourd is manufactured in a white
(sun reflecting), high-density polyethylene plastic, with
ultraviolet inhibitors added for long life. Since the color in
molded in, there is no need to paint it, and the white reflects
heat, thus helping keep the inhabitants cooler.
The Troyer Horizontal Gourd weighs approximately
21.4 ounces and it's sturdy construction should last for many years
of martin habitation.
The Troyer Horizontal Gourd has an access port
molded directly onto the side of it. This access port is covered by
a standard 120mm threaded cap. This port is 4" in diameter, large
enough to admit a human hand even while holding a fat nestling or a
handful of pine straw or wheat straw. The cap has a liner that
renders it and the access port totally watertight when in place. A
landlord merely twists the cap off to do nest checks, nest
replacement or end-of-season cleanouts. The access port has a high
degree of viewing angle, giving easy viewing of nest contents during
The Troyer Horizontal Gourd looks just like a real
(natural) gourd hung horizontally on a rack arm. It's shape leaves
no question in the mind that this is a gourd. The features are
softly blended together giving a gentle transition of shape without
any sharp edges or points for the adult birds, their young or the
landlord to get hurt on.
Birds eye view
Below is a bird's eye view of what the birds are seeing
from the inside of the gourd. Lots of distance from any
access. Plenty of room for a hand in the 4" access hole.
