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.
