Looks interesting....have you used this type of housing before? Perhaps the exterior of the boxes could be spray painted white to help keep the internal temperature of the box a bit cooler during hot and sunny weather.

Good luck!

Hi randyM, These are the first ones I have tried but I built an aluminum T-10 for last season with 12" deep cavities and it had 5 pairs in it. I painted the outside white and I really don't believe painting the inside white would make any difference. With the 2 " round louvered vents on each side should give them a good air flow and a place for any heat to escape. Here is a photo of them painted white and inside pic also. Some gourds that are used have black interiors and it makes no difference.

Martin Colony History: I have had my martin colony on the dam of one of my ponds for nine years. The colony has grown each year, but I am now concentrating on helping friends and acquaintances who have shown interests in martins. My colony consists of three T-14's with 8 Troyer gourds attatched to each T-14, a Troyer gourd rack with 12 gourds, and another gourd rack with 18 Troyer gourds for a total of 96 nest cavities. I am having serious predation issues with hawks and owls and am experimenting with various hawk guards and "screens". Established successful supplemental feeding the last few seasons and have had a blast flipping mostly meal worms and some crickets. Faculty from Ohio University are using my colony as a research site to study parasites that target cavity nesting birds. In exchange for access to my bird trail nest boxes and martin housing, they are banding all birds involved in their study.

Dale D,
I am curious how you are going to mount your mail box cavities, and what type of hoisting method you will be using to raise and lower the boxes.

mwren, I have designed to slide onto my existing GMA's and pinned the same as gourd. I have 3 poles all with winch and cable. These 4 mail box cavities will go on my B&B rack with 4 Bo9 gourds. This still has to be painted white.

Did you go this route because they were cheaper than gourds?

The Martins will definitely use them. A guy on our lake put a mailbox with the door open on the end of his boat dock. Martins built a nest in it and raised young. It did have shade in the afternoon from trees on the shoreline.

Seems like they would be really hot during the summer in Orlando.

Spiderman, price had nothing to do with it. I simply enjoy building my own housing and racks and trying types of non traditional housing. I have 20 gourds hanging and a T-10 house I built with aluminum. Everything is well vented and has posed no problem for me since 2004. Everything you see in this photo with the exception of the gourds I built myself including the replica AAA-16 rack. The box in the photo still has to be painted white. I just posted it before painted to show how they would be mounted.

Great idea and construction Dale. I guess you could say you were thinking outside the box. Yes, pun intended. I really do like the concept of a larger cavity such as this mailbox, easy to do nest checks and vented. Good job Dale.
ImageMite control, heat venting, predator protection and additional feeding during bad weather add up to success.

Thanks Dave, I placed a vent on both sides of the box to get good ventilation. The nice thing about these is 3rd vent could be place on the back of the box as well if wanted.

The T-10 is Beautiful. I bet that took some time to build from scratch.

You have a really nice site. I'm sure you take Excellant care of your Martins.

Thank you, Spiderman. The aluminum T-10 in the this picture took me twice as long to build as my old wood T-10 that I retired after 11 seasons. The old wood T-10 weighed 82 lb and this aluminum with nest trays weighs 50 lb.
