"Cornstalk disease" is the name given to the cause or causes of death of cattle allowed to run in fields of standing cornstalks from which the ears have been gathered. It is probable that "many different maladies have been included under this name." In Nebraska, however, there is such a similarity in the symptoms reported by the farmers that it seems probable that the great majority of the losses attributed to cornstalk disease are really due to some common cause. As to the exact nature of this cause nothing is known. However, various theories have been advanced, and methods of prevention or treatment based upon these theories have been described.

Bird damage to commercial fruits has long been a problem in many coun- tries, but the true magnitude of the damage incurred is difficult to determine objectively. Often the opinions of fruit growers provide the only measure of importance. In 1972, the U.S. Fish and Wildlife Service, the Michigan Department of Agriculture, and the Statistical Reporting Service of the U.S. Department of Agriculture obtained quantitative information on bird damage to tart cherries (Prunus mahalob) in Michigan. The results of the survey are presented in this paper.

The Fifth Vertebrate Pest Conference drew a registered attendance of 239 with an estimated additional 50-75 persons who attended portions of the conference but did not register. As in past conferences, the attendance was made up of individuals having varying interests in vertebrate pest problems from twenty two states plus the District of Columbia. Participants from Canada, Denmark, England, Germany, India and New Zealand contributed greatly to the success of the conference and provided further exchange of information on an international level.
