    • Obsidian was milling near a seawall in a canal near Three Sisters Spring. He traveled out to the main canal and followed a cow/calf pair briefly. He made a quick trip into the spring but turned away when approached by snorkelers. He moved back into the main canal and settled in a lush lawn of Eel Grass with another manatee. He began eating and did not stop even while his tag was exchanged. He appeared to be in good condition.

    • Obsidian was feeding on submerged vegetation near the shore in Crystal River. He paused as Carmen approached and interacted with her briefly. She passed him and he milled around the area before going back to feeding. Gas was observed. A body condition assessment was conducted. He appeared in good condition with a rounded belly. He did have new prop scars on his right peduncle.

    • Obsidian was resting near a secluded spring in Kings Bay. He started milling along the edge of the seawall, grubbing on the ground and rocks, with bits of vegetation floating up behind him. He grubbed his way out of the little cove and joined some other manatees in deeper water. It was not clear exactly what he was doing, but the water surface around all of them was covered in bits of vegetation. Gas was observed and his respirations as he milled was every 4-5 minutes.

    • Obsidian was resting in a shallow area off Kings Bay. He moved around slowly then began grubbing on the river bottom. Clumps of vegetation started floating up around his head. He reached his head up high to grab some reed stalks floating in the water and a couple of times did a slow roll. While rolling his head and shoulders came out of the water and his neck underneath and head looked well rounded. He moved back to his original spot and rested a little more. At exactly high tide he turned and traveled out of the area.

    • Obsidian was milling in a cove off Kings Bay. He settled in to rest but was disturbed by a tour boat leaving the canal.  He settled back down to rest and did so until another boat entered the cove. He milled around under a dock until it left.

    • Obsidian was resting in a cove off Kings Bay. Some manatees started moving into the cove and Obsidian moved over towards them and began socializing. As more animals moved in out of the wind, Obsidian moved towards shore and was foraging on the bottom, with bits of vegetation floating up around him.

    • Obsidian was resting in a small cove off Kings Bay. There was a report that he had a possible pec injury, but there was no sign of one and he did not seem in distress in any way. He rested for most of the observation, changing position each time a tour boat moved into the cove. In an hour and a half, nine boats entered the small space dropping off snorkelers. Though they all tried to stay clear of him, the amount of people limited the places he could be away from them.

    • Obsidian was resting near a sea wall in Kings Bay. A body condition assessment was conducted finding him with a mildly rounded belly and in overall good condition. His cold stress lesions seem to be healing well and no new ones noted. He started milling down a small canal but returned and then traveled into a cove. He found a quiet spot and bottom rested for the remainder of the observation.

    • Obsidian was milling in a cove off Kings Bay. the wind was starting to pick up, so he found a spot behind a dock and took a long rest. There were a few manatees in the back of the cove making a commotion and Obsidian moved near them. Having checked out the happenings there he moved towards another group of manatees, not as rowdy, and socialized with them.

    • Obsidian was in a large cavorting group in a spring in Kings Bay. Their activity riled up a lot of other manatees in the spring, causing what could only be described as a mass manatee explosion. Once everything settled down, Obsidian started calmly socializing when a new group of manatees entered the spring and the cavorting began again. Eventually, Obsidian broke off and rested under a downed tree for the remainder of the observation.

    • Obsidian was socializing with many other manatees in Kings Bay. After engaging with them for a while Obsidian moved off to rest. Some new manatees entered the area and Obsidian returned to the activity. The pattern of resting and reacting to new animals was repeated for the duration of the observation.

    • Obsidian was milling near a dock in Kings Bay. Some Eel Grass was floating on the surface and he was pulling it down and eating it. A kayak group encroached on him and he moved away from the food. Due to a language barrier it was difficult to explain the tag and how to passively observe the manatee. Once they moved on, Obsidian moved back to his original position and milled around the docks.

    • Obsidian was traveling out of a spring area towards Kings Bay. He encountered several groups of kayakers and a couple of boats which caused him to redirect his path. He finally went back into the spring and began socializing with a mom/calf pair. He stayed with the pair and they all started surface resting in the sun.

    • Obsidian was resting just outside the power plant boundary. He moved into the plant canal and milled around the boat ramp. As the tide turned, he moved to the other side of the canal and drifted with the current, resting on the surface. A team from FWC and CMARI caught him for a full health assessment. He had some cold stress lesions and had lost some weight but was determined by vet staff to be in good condition and therefore relocated to Three Sisters Springs. After being released into the spring he milled around for a while before settling in a restricted area away from swimmers.

    • Obsidian was traveling out to the west end of the power plant canal. He reached the boat fence and began traveling back east. He stopped about midway in the canal and began to rest.

  22. 01/06/2020 09:45 AM
    • Obsidian was bottom resting midway down the power plant canal. A mom/calf pair traveling into the canal got his attention and he followed them down to the creek in the eastern part of the canal. They went to a small creek, socializing with a couple of other manatees that were there also. He spent the rest of the observation resting in the outfall of the creek. He does show signs of cold stress. A health assessment and possible relocation is being planned.

    • Obsidian was at the East terminus of the power plant at the spring seep with another manatee. The two were interacting with each other and then Obsidian followed the other down the canal. Though it looked like he was on a fast track out, a mom calf pair passed him in the opposite direction and he u-turned to follow them a little way back into the canal. He engaged with them briefly before returning to his travels. He went about a mile down the canal before turning around which again seemed to be in response to another manatee coming into the canal. Obsidian joined the newcomer at another small spring then they parted ways. Obsidian continued west for another .25 mile, he remained out there for 20-30 minutes before moving back into the canal, this time at a more leisurely pace. He found a very sunny spot and began to surface rest. His respirations were 5-7 minutes apart based on his activity level. He does appear to have some marks that look like prop marks and the start of some cold stress. This canal does not have a supplemental heat source, so he will be monitored extra closely.

    • Obsidian was interacting with another manatee in the power plant discharge canal until that manatee moved further down the canal. Obsidian milled around the canal for a bit before starting to bottom rest. A mom/ calf pair moved down to where he was, and he followed them to the spring seep. He moved in and around the seep before bottom resting again. His respirations were every 5 minutes when active and every 9 when resting.

    • Since his release, Obsidian has made his way out of Crystal River and to the power plant discharge canal. Having secured access to the area, it is now possible to get a visual on him. He was bottom resting about 500ft down the canal where the water temp was 19.5. He followed two other manatees a little further down the canal, broke off from them to follow a different manatee back towards the start of the canal, where the water temp was 21. He stayed in this area exploring the perimeter, stopping in a spring seep, flowing into the canal. He would occasionally move out to the center, engage with the manatees there, then go back to the seep. He did not appear to have any signs of cold stress

    • Obsidian was released into the spring at Crystal River. He made his way to the entrance then turned around and came back into the spring. He met up with Sriracho and Slate as they were released and the three explored the spring. Though he would occasionally swim close to snorkelers he did not approach them.
