RE: Grey-breasted Martins

Very interesting. My parents have a big purple martin house and always love having them in the backyard in the summer. Sadly, the last time I took it down and cleaned it out for the winter, I closed all the doors to the inside nest spaces. My Dad passed away in December and I doubt if the house will get opened back up for the martins this year 🙁 I should have done it when I was there in early March...
