Do you have to go through the same registration process for dove at the state refuge that you go through for pheasant and duck?
On the areas that don't require a reservation it's all just a simple free self registration. Don't be caught w/o it however. I'll never forget watching the area manager of Gray Lodge standing next to the check station with a warden almost yelling at two guys who didn't fill the little card out.
Some places have doves the whole first half of the season but in my experience most are shot off the first day. The area I hunted had to have had 3-5 hundred birds shot that day and I bet the guys who shot a limit in the morning were back at it in the afternoon.
I'm going to wait until next week and see if any new birds have moved into the area but based on the past it will be poor.
The walnut orchards in the area were full of doves with nobody hunting them so there is a pool of birds but the small amount of food planted on the areas can't compete with the thousands of acres of chopped safflower region wide.
My best late season shooting has always come next to a pond with a roost tree near it. Sit in its shade and the heats tolerable. The hard part this year is finding a pond with any water in it.
