Good morning,

I am new to this forum and will have my first purple martin house this year. I have acquired a beautiful wooden house which has traditional entrance holes in it. Is it possible for me to make my own crescent entrances? I was thinking of using 1/4 " exterior grade plywood with a good oil primer. The holes are also protected from the weather by the porch above it.

I know that I will have to make additional cuts to make the crescents work with the existing holes. I just hate the thought of constantly fighting the starlings and possibly losing a group of martins.

Thank you for any help you can provide me.

Yes, specs are available. But the PMCA shop (and others) offer adapter plates you can use. The link to the appropriate page of the PMCA shop is below. -- John

The plates are the best way to go. Its difficult to get the wood exactly correct, at the correct height, and you will need a caliper to measure the entrance that you cut. (the height is very critical.) The entrance needs to be about 1/8in above the floor if you use a tunnel or a porch.

Please Make sure u have a repeater nest box trap to catch & kill the trash birds bc that's the only way to have a successful colony!! Just thought I would let u know!!

Thanks for your help. One more concern.......the compartments are not enlarged/roughly 7x7. From what I have read these compartments are too small for crescent plates. Am I right?

My suggestion based upon your desire to change over to crescent entrances is add a tunneled entrance that will already be equipped with a crescent entrance, wing entrapment guard and extend the depth of the compartment all at the same time.
S&K makes a tunneled entrance that has a mounting plate attached that makes it easy to install and has a depth of almost three inches with an outside and inside porch. You deepen the compartments as well as provide a starling resistance entrance this way.
2017-5 pair
2016-4 pair- 18 hatched-18 fledged
2015-1 pair -Both ASY- 6 eggs-5 fledged
2014-2 pair- 1 ASY-M/SY-F-1 ASY pair - 7 eggs-7 fledged
