During a 3-week period in July of 1964, Game Section personnel with assistance from Biology Section and Conservation Officer personnel carried out drive-trap waterfowl banding operations on marsh areas in the northern part of Iowa. This was the fourth year that drive-trap banding operations have been carried out in the state. Several days prior to the actual banding operations were spent selecting areas to band. Areas were selected that had a good population of local birds and vegetative cover suitable for banding. Young birds can be extremely difficult to drive on heavily vegetated marshes of emergent vegetation, and marshes lacking emergent vegetation seldom produce very many young birds.
