Homosassa River
Background He is the now-weaned calf of Dmitra, a manatee from Florida's west coast that also was followed by Journey North last year. Both Ivan and Dmitra were tagged in the Homosassa River on 26 Jan 1999. Scientists first met them in Feb 1998, wintering in the warm spring waters of Crystal River. Ivan was probably born in the summer of 1997.

When we last left off, Ivan's tag had stopped transmitting on 13 Feb 1999, which Susan and Jim determined to be due to a boat strike to the transmitter housing. Dmitra and Ivan were seen together through the winter of 1999. The last visual sighting of them together was on 4/12/99. Dmitra was seen on 5/10, without Ivan, so he was weaned sometime between 4/12 and 5/10! Ivan returned to the Homosassa River in Dec 1999 as a "first year independent", dragging his second boat-struck transmitter. Jim was able to remove the damaged transmitter and replace it with a new one on 6 Jan 2000. He is fine!
