Hunting pheasant without a dog isn't luck - it is tough work, but it can be done. I'm actually more successful without a dog than most of my friends who do use one.
*****I'm not talking about true hunting dogs that are bred and TRAINED to hunt, of which I see very few. Most dog hunters I see spend most of their time blowing a whistle and irritating everyone else while they try to round up their dogs. A well trained dog is awesome to watch, your french poodle / pitbull mix with an orange collar is not the same thing******
Good places I've found are: swampy areas, heavy thorny cover, thick undergrowth along the woodline. Our birds do not have a subscription to Field and Stream, and do not know what the "classic" cover looks like, so they go where they think it best.
The Mass fish and wildlife site lists the WMA's where they stock birds, hitting these areas will obviously increase your chances.
One thing I do is to only load two rounds. I've never hit with the 3rd, 4th or 5th shell, and you just let everyone know to head your way to find the bird you missed. Fire only two, everyone will think you scored, and you have a chance of kicking up that bird again.
Walk slow, zigzag, pause often, start your movements suddenly. Kick "birdy" looking clumps, and expect the bird to flush from where you're about to step.
The best part of a dog is getting your bird after the shot. I carry several 3 foot sections of flagging tape tied to a heavy nut (not me) or something similar. After the shot, drop one where you took the shot from so you can start over again when you get turned around. Throw a second one where you saw the bird go down, so you have a good place to start looking. Once you get to where you "thought" you saw it go down, you'll soon discover you haven't got a clue where you are or where you started from - the tape will help a lot to keep your bearings.
These birds blend in amazingly well. You'll have a tough time finding a whole bird, just look for a feather, your more likely to find the bird by looking for a piece of one, than the whole thing which is very easy to miss in even low grass.
