4 satellite transmitters for American bittern were put on previously radio collared birds in late July and August, 1998. This is experimental in collar design, transmission sequence, and location success. The objective is to determine migration timing, route and wintering area. Two birds from Agassiz and two from central Wisconsin have been tagged. The transmission sequence this year will be once every 10 days in July and August 1998, once every third day in September through November 1998, once every 10 days during the winter of 1998-99, and once every 4 days in April and May, 1999. Based on this year's results modifications will be made to tag additional birds next year.

Due to the small battery on these bird collars only 56 days of transmission are possible.
