Rita was released at Blue Spring State Park on Thursday, 2/26/09 with Amber.

Field Notes:

2/26/09: Rita was released at 10:30 am today into Blue Spring, now wearing a red and green tag.  She went out to the river within an hour of her release and encountered seven passing boats.  When each of these approached Rita dove and stayed submerged for at least one minute, already exhibiting wonderful boat-avoidance skills.  An hour later she returned to the spring run, socializing with other animals including Amber who was released half an hour after Rita.  At 4:30 pm Rita was milling around the spring run closely followed by Amber.

2/27/09: Both Rita and Amber were sighted this morning at Blue Spring State Park by Wayne Hartley, and had both moved out this afternoon, Rita to the oxbow just south of the spring and Amber a short distance to the north of the run.  Currently, at a little after 6 pm this evening, they have entered the spring run again and are now milling around there, close together.

2/28/09: Rita and Amber have spent this morning in the spring run at Blue Spring State Park.  At 10:45 am they were sighted about 30 yards apart in the run. 

3/2/09: Since her release Rita has spent a great deal of time at Blue Spring.  She has gone out into the river a few times but never travels very far and returns shortly after.  She is there again this morning, hopefully in response to the cold front moving in.

3/6/09: Rita stayed at Blue Spring again today.  She was observed socializing with Bock at 7:45 a.m. and bottom-resting with three other animals at 11:00 a.m. 

3/7/09: Most animals are now leaving the spring run.  Rita was milling around the southwest edge of Lake Beresford around 12:20 this afternoon, but by 3:30 pm had returned to the spring. 

3/10/09-3/16/09: Rita continues to stay mostly at Blue Spring but makes short trips north or south into the river every few days.  She has not been observed feeding yet.  She was observed bottom-resting alone near the entrance to the spring run on the afternoon of 3/11/09.  On the morning of 3/16/09 she was in the bend of the oxbow north of Blue Spring and across from French Landing.

3/17/09 – 3/24/09:  Rita was observed feeding this week on pennywort in the oxbow just south of Blue Spring on Tuesday, 3/18/09.  Soon after that she began traveling south and by Wednesday was in Lake Monroe.  Since then she has spent the week moving up and down the south shore of the lake.

3/23/09-3/30/09: Rita was observed with at least one other animal on Wednesday, 3/25/09, in the small marina just north of Lake Monroe, and by Thursday, 3/26/09, she had moved down into Lake Monroe, moving along the south shore and out towards the center of the lake.  She was seen in the Sanford marina with four other animals Saturday, 3/28/09, cavorting and possibly bottom-feeding.

3/30/09-4/6/09:  Rita had gone south from Lake Monroe into the channel to the southeast, then north in the channel again just below the lake.  On Monday morning, 4/6/09, she was seen milling and cavorting on the east side of Sanford marina with 3-4 other animals.  She seems to stop by the marina every few days.

4/7/09-4/13/09:  Rita spent last week at the southeast end of Lake Monroe. At the beginning of the week she was milling around the east side of Monroe Harbor with 4 other animals.  On Monday, 4/13/09, she is now at the southern edge of Mother's Arms.

4/15/09-4/29/09: Rita fed in Woodruff Creek southeast of Lake Monroe on Thursday, 4/16/09. She was with two other animals. She has been moving between Woodruff Creek and the southeast portion of Lake Monroe.
Rita was with 5 other animals on Friday, 4/24/09, cavorting, socializing, and feeding.

4/27/09-5/14/09: Rita was seen west of Sanford Marina in Lake Monroe close to the wall on Wednesday, 4/29/09. She was still with the group of 5 animals, cavorting and socializing in shallow water. By 5/6/09 she
had moved to the other side of the marina and appeared to be involved in a mating herd. From 5/10/09-5/14/09 she still socialized with the other animals but did not often seem to be the focus of the mating herd.

5/12/09-5/18/09: On Wednesday, 5/13/09, Monica Ross gave Rita an in-water health assessment where she had spent the last week:  just east of Sanford marina.  Rita appeared healthy with no longitudinal folds on her 
belly.  She and the others were feeding on bottom vegetation, cavorting, and milling about 50 feet from shore.  For the past week she had been involved in what appeared to be a mating herd, so she is being watched closely.

5/23/09-6/4/09: As of 5/23/09, Rita has traveled southeast from Lake Monroe and is currently on the west side of the channel at 415.

On Friday, 5/29/09, Rita moved north back into Lake Monroe. She was feeding with 3 other animals in Big Smokehouse Cove.

6/3/09-6/9/09: Rita fed and socialized with one other animal in a small creek at Stone Island in Lake Monroe on Tuesday, 6/9/09. The area was small and enclosed, and it appeared to be protected from most boat traffic other than residents who traveled at slow speed.

6/10/09-6/15/09: Since Saturday, 6/6/09, Rita has been in the small canals at Stone Island on the northeast side of Lake Monroe with one other animal feeding, milling, and bottom-resting.  She was seen milling and bottom-resting on Thursday, 6/11/09.

6/16/09-6/25/09: Rita has spent the last week moving around in the creeks off of Bethel Creek Cove at Stone Island.  She was traveling in the cove on Wednesday, 6/17/09, and bottom-resting near the entrance to the creek on Monday, 6/22/09.

6/26/09-7/01/09: Rita moved from the creek at Stone Island south and east to the eastern end of Lake Monroe with three adults and one calf.  Since then she has remained in that area and on 7/1/09 has begun to move west across the northern end of Lake Monroe.

7/2/09-7/9/09: After having some problems with Rita's tag over the last few days, the signal was heard on 7/9/09 off the Sanford Marina on the south shore of Lake Monroe.  Rita's tag will be changed as soon as possible.

7/9/09-7/14/09: Rita's tag was recovered on Friday, 7/10/09, just east of the Sanford marina by Monica Ross and Melody Fischer.  The tag was found lodged between two pilings of the fence on the east side of the marina and broken off at the weak link of the tether, perhaps as Rita was passing underneath the fence.  Rita's belt was not heard.  We are working on belt-tracking Rita to re-tag her as soon as possible.

7/15/09-7/21/09:  Sea To Shore was shocked and very saddened to get reports of a large female manatee found deceased north of Lake Dexter in the Astor area on Thursday, 7/16/09.  The animal matched Rita’s description and was later confirmed to be her.  Andy Garrett of FWC reported results of the necropsy:  no broken bones or external wounds, abundant fat reserves, food in her stomach, and mating scrapes.  The cause was listed as natural.

It is estimated that Rita lost her tag in Lake Monroe on 7/4/09 and traveled north to Astor between then and 7/15/09.  The tendency to travel far after a holiday weekend or other period of boating activity is not atypical; reasons for this could range from boating activity to harassment from males interested in mating.  Sea To Shore had been searching for Rita all around her last known location in Lake Monroe and then expanding the search north and south from there.

All behavior observed from Rita since her release in February indicated a manatee who was adjusting very well to the wild again.  She was seen feeding during almost all of her observations, socialized often with other manatees, and showed skill at avoiding boats.  We are very sorry to report this news.
