    • Millennium and Falcon were surface resting together. Another manatee was resting nearby also. An in water assessment was conducted noting that their body condition looked good, with slightly rounded bellies. Around 4:00pm they traveled out to the grass flats in the bay. They settled in a spot and began to feed. This activity slowed after 45 minutes and appeared to be resting. A few other manatees came by rousing them. The twins followed them to another spot further off where the feeding appeared to begin again.

For the rest of the observation he moved between eating and socializing. Gas was observed.

    • Millennium and Falcon were still side by side bottom resting in the canal. An in water health assessment was started. They showed no interest in the swimmer and started to move slowly out of the canal. The stopped and returned back towards the boat. The swimmer approached again and they did not show interest or attempt to leave the area. It was determined that Millennium was slightly leaner than Falcon with a flat belly, but no folds were felt. The canal they were resting in was very deep and no vegetation could be seen however the surrounding area outside the canal was full of Vallisneria (Tape Grass)
