My backyard birds have just started to become extremely vocal (southern MS). Tom popped off a couple gobbles in the pitch black last night as I was gathering chicken eggs. The hens are really starting to squawk as well. The gobbler struts most of the year since he isn't separate from the hens, but he started back up with the spitting and drumming a week ago. He should be topping the hens in another week or two, and I expect eggs shortly after that.
Our local season opens up this weekend in MS, but birds haven't started breeding quite yet, even with the unbelievably warm spring.
I did have a bluebird start a next last week in a box, earliest I have ever seen that happen...
