Griffin NestboxIn addition to Messages that have appeared in the Bluebird Mailing Lists on this topic, the following are on the Audubon Society of Omaha website: Date: Thu, 15 Jun 2000 20:17:03 PDT Joe Schultz The Griffin box is a nice little box named after a BRAW board member Shermin Griffin. It has a side as well as a top opening for viewing and cleaning. The floor is 4"x5" and the entrance hole almost 6" from the floor. I have one on my trail right now that just fledged 5 BB. It's the box I am considering switching to when my Petersons are shot.It also has a wood predator guard. The Treebranch nestbox is the product of another WI person Frank Zuern from Oshkosh WI. I did not have good luck with it but a fellow from the Eau Claire area who has a 300+ box trail said it works for him. I know he is in very good BB country. Joe S. Date: Fri, 16 Jun 2000 06:44:00 -0500 Keith Kridler Mt. Pleasant, Texas Being a building contractor I am always interested in "new" designs. I know that in California Linda V. and Dick Purvis are working with the "two holed" box. In my original birdhouse book by John K. Terres first printed in 1953 titled Song Birds in your Garden (actually printed before I was born) one of his plans calls for a "four holed" nestbox for increasing tree swallows as it allows each young to gap for food at it's own door so that in cold weather the adults don't have to enter the box to feed. One hole 1&1/2" and three holes just 1" diameter large enough to feed through. Sounds like the "griffin" box is just a modified "Duncan" style box that has been used for 80 years. T.E. Mussleman and William Duncan probably built and experimented with every style box we are using now or at least a very close style to them! To me any box with a low sloping roof that drains towards the front and is basically or slightly rectangular i.e. 4"X5&1/2" is still a "Duncan" style! Larry Zeleny and John K. Terres used the "Duncan" style with the addition of a dowel rod or square stock to help seal the crack between the roof and the back of the box. The "Griffin" box sounds like the boxes we make for school children that end
up being 4"X5&1/2" as this way you do not need to use a table saw to rip the
wood. 6" is the universal "standard" depth of bluebird boxes and just sounds
like adding a predator block is not changing the basic style too The Dick Tuttle style basically covers all nest boxes that are square or slightly rectangular that have a flat roof design. I know this is really not quite right but there are only so many ways to nail 6 pieces of wood together to build a nestbox! KK Date: Fri, 16 Jun 2000 10:20:50 -0400 I think we're closing in on it. Can anyone explain how this "Griffin Box"
DIFFERS from what I call the NABS/Stokes box? I gather that it opens from both the side and the top, right?(I call it 'Stokes' because the plans for it
are in Stokes's "The Bluebird Book.") All I've added on mine is the wooden
entrance block, with kerfs. Date: Fri, 16 Jun 2000 18:58:16 PDT Joe Schultz The Griffin box features both a side and top opening. The side opening facilitates cleaning and checking for blow flies. The top opening permits easier and safer monitoring of the chicks,especially when they are near fledging.Top-9'x 7 1/2".Back-17"x5-1/2".Sides-11"x10"x5". Front-10"x5-1/2".Bottom- 5"x 4". Predator Guard-5-1/2"x4". 1.The lumber is 3/4".The entrance hole is 1-1/2" dia. There is a top cleat 1"x5 1/2" that the removable roof end slides under to help hold it in place. I hope this helps a little in your quest for the Griffin Box. Date: Fri, 16 Jun 2000 19:39:42 PDT To Barry and list... Joe Schultz |
