No birds

I have been out hunting for partridge and i swear there is no birds this year. I went out several times and walked and walked without any luck. I would go to all the good spots i know and not a thing. There was lots of food for them but no birds. One time i walked probably 5 miles and saw only two, without the chance of shooting them. So far i have not shot a bird yet this season and it is depressing. Then my dad went up to the copper country for the weekend and shot five. I went up there and once again, saw not a thing. It is really getting frustrating when you can't even find birds to try and shoot at. Then my friend and i went out to national mine where we saw a few take off at once but he was in front of me so that i could not fire. Then we bushwacked through a swamp following the birds and we then split up. i went left he went right. And the bird apparently went right so my friend shot one and once again i got skunked. So far i have not had a successful bird season.
