Ted, I was interested in your post regarding lesser pinnated grouse. (Yep, I am stuffy about correct names. Charley Waterman loved to give me a hard time about that. He would come up with some of the most obscure nicknames for birds he could think of when we talked.)
I can't offer any help regarding Kansas for lessers. I did shoot my greater there. But in 1985, '87, '88, and 1991 Marge and I went to New Mexico for lessers. To say that our success was excellent is lacking. In the '80s there was a very strong population around Milnesand and Pep, New Mexico. In those years there were a lot of milo being grown in the region. My guess is that is why there were so many grouse there. Also all hunters (and there were a lot opening weekend, in fact the Milnesand Community had a "chicken" breakfast for hunters at the fire station)
shot the birds as they flew out of the prairie into the milo fields. Much like a dove shoot.
Marge and I walked the prairie for them. I was using a 12 bore pigeon gun, and those full/full chokes were certainly a big help. Close shots were 50 yards. Most we didn't even shoot at.
When we went back down in 1991, all the milo was gone. And we had to walk about 10 miles each day in order to find the few birds we did. I think it was just a few years later that the season was closed in New Mexico. I have no idea what the current status is.
But what may or may not help you, is I think (???) Texas still has a two day season for the grouse. I think the area with the grouse is directly west of Lubbock, right on the New Mexico line. One ranch we hunted in New Mexico was right on this line, and it seemed that flushing birds flew over to Texas. As I am certain you know, pinnated grouse fly a very long ways!
I wish you all the best in your quest to bag one. Of all our upland birds, I rate these grouse (both greater and lesser) pure treasures, without equal. Best, Worth Mathewson
