I don’t know if they are different females. It’s 3-5 days each time a female would show up. He presents her the box. She would look it over for 15-20 mins. Then she would fly off. In between that time he’d do his calling. The female started building her nest thursday morning. I still see the male in the morning. I haven’t seen her since. Like I said in my first post. It’s been rainy and cold here.
