§257.5. Prohibition Against Taking Resident Game Birds and Mammals by the Aid of Bait.
Except as otherwise provided in these regulations or in the Fish and Game Code, resident game birds and mammals may not be taken within 400 yards of any baited area.
•(a) Definition of Baited Area. As used in this regulation, "baited area" shall mean any area where shelled, shucked or unshucked corn, wheat or other grains, salt, or other feed whatsoever capable of luring, attracting, or enticing such birds or mammals is directly or indirectly placed, exposed, deposited, distributed, or scattered, and such area shall remain a baited area for ten days following complete removal of all such corn, wheat or other grains, salt, or other feed.
◦(1) The taking of domestically reared and released game birds on licensed pheasant clubs and other licensed game bird clubs;
◦(2) The taking of resident game birds and mammals on or over standing crops, flooded standing crops (including aquatics), flooded harvested croplands, grain crops properly shocked on the field where grown, or grains found scattered solely as the result of normal agricultural planting or harvesting;
◦(3) The taking of resident game birds and mammals on or over any lands where shelled, shucked or unshucked corn, wheat or other grain, salt, or other feed have been distributed or scattered as the result of bona fide agricultural operations or procedures, or as a result of manipulation of a crop or other feed on the land where grown for wildlife management purposes: provided that manipulation for wildlife management purposes does not include the distributing or scattering of grain or other feed once it has been removed from or stored on the field where grown.
I would sure be talking to the CA enforcement branch and get it in writing... I have found in the past regaredig wildlife laws, is that 1 section of the law will say it one way, but there are other laws that also come into play (ex: FED law). And without knowing all the various sections where the law may be written - and apply - you could be missing a vital part of the equation.
