Re: PMCA Wing Entrapment Protectors heads up....

IMO, if the new design is 1inch thick, martins should be able to navigate it. I might install them 1/32-1/16 inch above the entrance top to make their entry easier. The UHMW plastic is so slick. A good material they can sail through. Thanks, btw, for identifying the material. I really like it; howev...

Re: PMCA Wing Entrapment Protectors heads up....

Brad, I don't know their thickness either. I know you have an issue with thickness using rivets to install them. Those I covered the woodpecker damage with, I used 1 in. SS bolts and nuts, both plain and lock nuts. Bought them in packs of 100 from bolts.com for about $20 per pack. For me they are as...

Re: PMCA Wing Entrapment Protectors heads up....

I talked to PMCA today, advocating Brad's and Lewis' anti- modification position,as well as my own need to restore woodpecker damage (keep what you have) . I have gotten a reply from PMCA that the vendor, Mel at Hillcrest, has discontinued the making of the new taller,soft plastic WEPs. He has a sma...

Thanks for the heads up Brad. I join the others supporting the continuation of offering the original UHMW WEPs. While I have not experienced problems with wing entrapment in my conley2 openings, I have been deluged by one or more woodpeckers pecking out sizable holes at the top of the openings. For ...

Re: Time to change the name SCOUT

It's been a long time since I've picked up a dictionary to define a word to establish its meaning. I did google the word today and while the noun defines some military activity; the verb usage defines as a word meaning to look for some person or thing. That pretty sums up what James Strickland is sa...

Re: Troyer Tunnel Door Stops

Billie JR, Great product. Been around for several years. A plastic slide designed just like the metal trapping mechanism and can be substituted for the metal piece if you want. The value is that they cover the entire entrance discouraging unwanted investigation. I use them on all of my Troyer gourds...

Re: How Far Away Should Martin Housing Be From Power Lines?

I have 3 systems about 10 feet from power lines with cable lines beneath them. Power lines are about 10 feet above systems. Systems are 14 and 16 feet high and martins use all three as well as perch on power lines. Lower line is ground line. I have seen squirrels cross lines, but none have ever jump...

Re: A look at migration this week.

In spite of this arrival forecast from PA, a great surprise!!!, I had a large group of migrants flying into and over my colony, situated within 15 miles of the Gulf coast line, this evening. I suspect neighboring landlords saw the same. In my opinion similar arrivals will impact the entire Gulf Coas...

Re: SY Male?

I would call this bird an SY male, earlier in the molt process then some seen in the days ahead. I believe some of the black neck feathers will darken out in the coming weeks, and the black spot under its right leg, as well as a less defined spot under the left is indicative of a male. Plus the timi...

Re: Martins pair for season... or life?

I don't know how much interest you have in the northern cardinal but there was a gynandromorph found last year that is female on the left and male on the right (photo courtesy Shirley Caldwell). I've been wondering if this has been documented in purple martins and, if so, on which side the female p...

Hi Flyfisherman, I live in Corpus Christi and have colonies in town and at a site 35 miles (and 5-10 degrees hotter) west of town. I vent all of my gourds with a single 1 inch pvc elbow vent placed as high on the gourd so that its outflow is faced downward. At seasons end it's amazing how much gunk ...

Re: Clipping HSOP wings?

I, and others, have clipped the flight wings (one side) off of house sparrows used as live bait in traps. The reason being, if they escape when you pull out recently caught house sparrows, some predator--probably a roaming house cat-- will enjoy a meal. It also allows you to know which sparrow is th...
