Extremely informative. All the years I have had purple martins, I have worked and never took the time to do the homework of the different age groups of martins.
I am extremely happy and thankful to report that on March 6, 2025 I seen what appeared to be an adult male, didn’t see again until today March 12. With adult male are 2 other Martins, for sure one is a female and I’m not sure of the other.
There is an all out war between those 3 Martins and 2 bluebirds.
Totally my fault BECAUSE out of ignorance I have allowed box after box of bluebird boxes to yield bluebirds that I placed to close to the Martin boxes. Now I’m paying for it, so here is wha I’ve done. In January of 2025 the light came on so I relocated several bluebird boxes in the neighboring pasture away from the Martin houses. They are everything a bluebird could want. Seems they all took the relocated boxes fine except for one pair
Sincerely and God Bess from Many La.
