Re: Owl Predation

I never saw my owls reach into the openings and grab birds. The seven or eight inches between the porches and wire was ok for that. My owls would hang on the wire flapping their wings and making a commotion causing martins to freak out and try to escape. That's when the owls would grab. My new cages...

Re: Owl Predation

I guess I'm going to try to make my cages larger around my houses. I'm hoping to have around 12inches of space between porch and fence. I'm thinking about using goat and sheep welded wire which is a 4x4 inch mesh to try and keep the weight to a minimum. I've only used 2x4 inch wire. Has anybody used...

Re: Owl Predation

Thankyou all for the feedback. All my seven houses have 2x4 inch wire that is about 4-7 inches away from the front of the porches except the T14. I wrapped the wire around the T14 owl guards so that is only a couple inches off the porches. I've seen owls fly head on and crash into the doors and grab...

Re: Bad Storm = Bad Damage

Kyler, sorry to hear and see this. I've been thru bent trio poles in the past several times. I eventually bought new poles for my castle and minicastle and placed pipe or conduit inside them. They became pretty heavy duty. I did that six or seven years ago and haven't had any problems. But I still t...

Re: Owl Predation

Yes, they are barred owls, a male and a female. I have flood lights in my back yard that I turn on every night and I have motion detected lights on top of my poles. Never seen anything but owls. They attack between 9:30 pm to 5:00 am about every night. You are right Gray Fox, if they would just stay...

Re: Pole for T-14

Dave, that's the post I built in 05 for my T14. Again, it's in the Troyer plan book. The secret in laminating is that the treated lumber that's being used is dry. Also use a good waterproof glue like Titebond III or Gorilla Glue. And use lots of it on all sides. I think I stored the wood in the gara...

Owl Predation

It has been a long stressful seventeenth season, maybe my last. The barred owl predation has been bad. I've counted at least 25 piles of feathers below the colony. I wonder how many were defeathered somewhere else? I had caged everything up about nine years ago. It seemed to work well for awhile but...

Re: Pole for T-14

I built the laminated post that was in the Troyer's T-14 plan booklet. That was in 05. Still in use today. Straight as an arrow.

Re: Adjustable Excluder Entrances

Kyler, excluders from Nature House work well for me. They slide thru them nicely. Occasionally not often, would have to enlarge the excluder or a crescent for those birds that had odd growths 0n there bodies. One year a asy female had a large bump on her breast and was having a hard time going thru ...

Re: Cutting My Own Trio Entrances

I've been using the Nature House crescent and excluder doors for years and haven't had any trouble with starlings that I can remember. I have a castle and a minicastle and 2 M12K's, all using those two openings at the 1/2 inch above the porch level. I do use the 3/8 inch wing entrapment protectors o...

Re: Crescent doors

You can buy from PMCA Trio doors that are crescent or excluder openings. Replace the round openings for the crescent openings. No work involved.

Re: Hawk

Brent, I use heavy duty galvanized wire and install vertical on every perching station on top of each house. They are about 8-10 inches long and spread out across the perches to keep hawks and owls from landing. At least it's more difficult for a larger bird to land. The martins can still use the pe...

Re: Didn't understand wing entrapment until...

We should not forget wing entrapment on a inner hole like when somebody expands their house from 12 to 6 units by cutting a hole into the next compartment. My trio castle that I bought years ago came with inside holes that were 2 inch round. The house came with caps that could be placed into the hol...

Re: Housing questions

I had a heath house like yours and modified it from 12 to 6 compartments. It was hard to do proper nest checks every 4-5 days. The telescoping pole quit telescoping because it got bent a little in a storm so the sections wouldn't slide down into each other. When they did slide down into each other a...

I use 10 feet long 1 inch id pvc pipe and install decoy on one end. The other end goes in a little larger pvc pipe placed in the ground around the colony. I have four decoys, probably should have more but they work well especially if they are swaying a little in the wind. I never liked them on my ho...

Re: Multipurpose pole/rack setup - need feedback

I have a multipurpose pole and I don't think there would be any problem. If the hub wanted to stick you could add a little weight next to the feeding tray to balance out the hub.

Re: Bluebirds

I think a 100 yds is still recommended between bluebird boxes. Sometimes that distance on my trail is not far enough. Distances left then 100 yds sometimes work if there is an obstruction between boxes like trees or a house, something that keeps the birds from eyeing each box. Some places on my trai...
