The "squeaker" you are referring to is probably a "mouse" squeaker. Not the same thing as a squirrel call. Squirrel calls mostly imitate the bark, or chirp of a squirrel - usually the alarm call. You might find an old Herter's someplace, or one of the Olt models (S-8 or B-10), maybe a Mallard Tone or a Lohman - there are lots of them.
No, only the "list gods" can delete messages now days on PM (for whatever their "logical" reasoning is behind that I don't know). Besides, you are not wasting space here at all - your question was valid, in the appropriate forum and deserves any answers or help other users will pass along to you. BTW, welcome to the board.
I also do the larger diggers in the Medicago fields myself, especially a ways north of here. I have not had the problem of them being gun shy, but most of my shots are at 200+ yards and with baby 17 and 22 centerfires. I guess that's neither close nor loud enough to bother them. Even the walking hunts I do with the 22 rimfires produce lots of "easy" shots inside of 100 yards. HTH
