This interesting structure has been put up a Minsi Lake to attract nesting Purple Martins. They are designed so that the birds can enter and lay their eggs but predators can't.
I would never have guessed that that was their function - I often wonder how the designers know what will work - I guess trial and error. I hope successful for the Purple Martins.
Thank you Helen, MIlanie, Katy, Diana, Issi, Jenn, Wendy, Haskar and Kathy!
Apparently they work rather well but to be honest I didn't see any birds coming or going in and out of them while I was there. It could be past their nesting season though.
