Manatee Tracking Updates from biologist, Monica Ross:
Mo Update 1/20/06:
We
attempted to capture Mo on
All
proceeded to the boat ramp, except Bob Bonde who continued to Three Sisters to
do some photoID. Upon
arriving at the spring, Bob
noticed Mo traveling up the run and notified Nicole Adimey which called the
troops to let us know Mo’s new location.
Permission to use the private land adjacent to Three Sisters had
previously been established, so all resources were switched for a land set.
There were over two dozen manatees resting in the large spring along
with
We
were able to obtain an excellent look at his body condition and Mo has
increased in abdominal depth since observed on
Also,
we will continue to try and get good body condition photographs for the group.
Water clarity has not been at its best when Mo has been in accessible
swimmer areas.
Thanks
again to everyone over the past month for being on continuous standby and
having the ability to help with minimal notice.
A special thanks to this capture crew that had to get up soooooooo
early to be ready to leave the refuge right after sunrise.

Animal updates and Bo's health assessment 11/21/05:
Bo
Bo
was captured on
Blood,
morphometrics, ultrasound, weight, fecal and skin were obtained.
Dr. Mike Renner from Miami Seaquarium gave Bo an overall condition of
good, with a body score of 3. He
gained 30 lbs since his last health assessment on
Ultrasound
readings showed decreases across the board.
Umbilicus reading was normal, anus reading fell just below normal and
peduncle reading was below normal. All
girth measurements are still below normal but it should be noted that the
umbilicus reading did increase since last capture.
Note his captive readings in January were below normal for the peduncle
and umbilicus girths.
Bo
received a new belt because the belt had received damage from a prop cut.
Shortly after Bo’s release into the sanctuary at Blackpoint, he
traveled back to the flood structure and began to bottom rest.
Visually,
Bo appears to similar body mass compared to other animals of his size in the
area. Monthly underwater visual
observations will be attempted to monitor his body condition going into the
winter season. Bo has been
traveling over the past month between Blackpoint and Deering Estate.
He has even been observed with one of our old friends, Brooks at Deering
Estate.

Douglas was retagged at Blackpoint...go Joaquin. And...........Bo's tag was heard today too just north of Blackpoint. The capture is still a go for tomorrow and again I say..."may the tracking gods be with us" (or should that now be the capture gods??)

Mo's Health Assessment 11/2/05:
Mo
was captured on
Blood,
morphometrics, ultrasound and weight were obtained.
No fecal samples were available. Dr.
David Murphy Lowry Park Zoo gave Mo an overall condition of good, with a body
score of 3. He lost 170lbs (16%)
since his release on
Ultrasound
readings showed decreases across the board.
Umbilicus and anus readings were considered normal and the peduncle
reading fell below normal. Peduncle
and anus girth measurements were considered normal and the umbilicus girth was
slightly below normal.
Mo’s
belt was tightened to help reduce further irritation to a new rub spot received
from this year’s belt. Rub spots
are not common but for some reason Mo is prone to these.
The
Mo
had been observed feeding on numerous occasions.
Thus, we were amazed at the amount of weight and fat he had lost since
his release. He is almost always
with other animals and is active and responsive, equivalent to other manatees in
the area. Monthly underwater visual
observations will be obtained to watch for any appearance of a concave belly
during this upcoming winter season.

Snorty Capture update:
We tried to catch Snorty again today but were unsuccessful! He very calmly and methodically went over the floats during the first set. During the next set, we put a splasher in the keep him away from the floats, so he disappeared under the leads. We had put a plane up to help direct the capture boat but Snorty had gone up a small creek and would swim without mud trail and was obviously not near the surface either. All this was for nothing anyhow...since he could easily get out of the net when we did have him in it. At this point, we are going to monitor him via VHF belt tracking only until the next scheduled health assessment. This animal is the most net wise animal I seen since "Ren" from Tampa Bay. He has excellent boat avoidance and his behavior has been normal.

6/16/05 Animal Updates:
Snorty:
Snorty utilized the areas between Lake Woodruff northward to Palatka’s Warner Cove and then south to Crescent Lake during the last part of May and into June 2005. He was observed with several other animals in Lake Woodruff during the last week of May. On 6/3, Snorty was observed traveling out of Lake Dexter heading north in the St. Johns River. He was located by ARGOS in Lake George the following day and then in Little Lake George on 6/6. Snorty was observed on 6/7 with several other animals still traveling northward along the St. Johns River north of Trout Creek (south of Palatka). Two days later, he was observed alone near Warner Point just north of Palatka. Snorty began to travel south the following day and made his way into Crescent Lake on 6/12. Unfortunately, Snorty lost his tag on 6/14 due to a gator bite to the tag (gator bite very apparent on the tag). Snorty was still in the area when the tag was recovered on 6/15 but a retagging attempt was not conducted due to high presences of large gators. If he moves out of the area to a safer location, we will attempt a retagging and if not successful or if he does not move out of the area soon, recapture options will be discussed to attach another tracking device.
Scarface:
Scarf utilized the areas between
Lake Woodruff northward along the St. Johns River to New Switzerland Point
during the last part of May and into June 2005. She
was observed feeding along the northeast shore of Lake Dexter during the last
week of May. Scarf began to travel northward in the St. Johns River on
6/1. She was observed with five
other manatees on 6/3 in Muddy Cove just north of Lake George and was still with
other animals on 6/7 just south of Trout Creek (south of Palatka). Two days later, she was observed with one other animal
near Rice Creek, north of Palatka. Scarf
continued her northward track and was at New Switzerland Point on 6/11.
The following day, she began to slowly travel south and was in Palmo Cove
on 6/16.
Bo:
Bo utilized the areas between
Blackpoint and Military canal during the last part of May and into June 2005.
Bo was observed alone on 6/1 traveling out of Blackpoint toward Princeton
canal. He was observed socializing
and bottom resting with four animals the following day in Blackpoint.
Over the next week, Bo made nightly trips out of Blackpoint to the mouth
of Princeton canal and then he would be back in Blackpoint the following early
afternoon. He was observed milling
around the dock slips of Blackpoint with one other animal on 6/12.
Unfortunately, sometime during the evening of 6/12, Bo lost his tag. The tag was recovered on 6/13 completely submerged under a
boat. We were lucky that the area
had received an extensive amount of rainfall and the flood structures had been
open allowing the saltwater basin to become freshwater. Thus, we were able to hear the tag’s VHF signal (which
doesn't transmit well in saltwater) even though the tag was submerged.
We searched for Bo and were not able to locate him on 6/13 but were lucky
to relocate him the following day when he joined up with the recently released
manatee, Douglas. After several
hours of attempts to sneak up on Bo (which was not being allowed by Douglas),
the two animals finally allowed us to get close enough to clip a new tether and
tag onto Bo’s belt. Bo was
observed on 6/16 with Douglas and several other animals inside Blackpoint's
manatee sanctuary.
Daisy:
Daisy has not been sighted
since her tag stopped working on 4/24/05. We
will continue our search for Daisy by monitoring the high use manatee areas and
will conduct another aerial survey of the area hopefully in the next week.

3/29/05 Animal Updates:
Bo and Daisy:
Bo and Daisy were released on 3/29/05 at Blackpoint Marina’s Manatee Sanctuary. At the time of release, we were unsure if there were any other animals in the area but about five minutes after the release, both animals were observed socializing with a wild manatee. Throughout the next hour, Bo and Daisy were observed socializing with each other and with up to six others animals in the area. Bo was even observed cavorting with a few of the other manatees. Just over an hour after their release, Bo and Daisy were both observed feeding on algae off rocks near the bank. Both animals remained in the Blackpoint Marina basin over the next few days. On 4/1, both animals were observed at the doors of Blackpoint’s flood structure diving down to the bottom with four other animals. This behavior is usually indicative of animals drinking at the seepage areas along the flood structure doors where the freshwater is leaking through.
Snorty:
Snorty was observed traveling north along the St. Johns River, north of Hontoon Island on 3/6 with a mother calf pair and one other animal. They were traveling along the shoreline and would dart under vegetation if boats got too close to their location. They traveled into Mud Lake and met up with two other animals and all then continued to travel north. It should also be noted that there was a lot of boat activity in the St. Johns on this day…142 boats passed these animals in a one hour period. Snorty was observed on 3/9 in Lake Woodruff feeding with six other animals. He was alone the morning of 3/18 in the Lake Woodruff area with water temperatures at 17 degrees, but that evening he traveled back to Blue Spring. On 3/21, Snorty traveled back to Lake Woodruff and was observed feeding with two other animals. He was again observed feeding on 3/30 this time with six animals in Lake Woodruff and there was a considerable amount of socializing occurring.
Scarface (aka Scarf---much more feminine name don’t you think?):
Scarface remained in Blue Spring after her re-reintroduction on 3/2 and remained until 3/14. She was observed in Lake Beresford with two mother calf pairs and one other animal. Initially she was observed alone milling along the bank when she changed course and swam in the opposite direction and meet up with another animal. She followed this animal into another area where there were the two mother calf pairs. All other animals appeared to be feeding on floating vegetation but Scarface appeared to be only observing and then bottom resting. When we did end the visual and depart from the area, all animals responded by avoiding our boat…including Scarface. She traveled north to an area north of Lake Dexter on 3/15 and quickly made a trip south to Blue Spring when the temperatures began to drop in the river on 3/18. Scarface remained in Blue Spring until 3/23 when she traveled north again to the Lake Dexter area. She was observed on 3/27 in Lake Dexter with several other animals feeding but she was very difficult to observe due to her reacting to the boat upon closer approach. Daisy was observed surface resting with eight other animals on 3/30 in Lake Dexter. Eight other animals moved into the area and most of the animals, including Daisy were observed feeding on floating vegetation. It should also be noted that Daisy has some cold stress blisters along her back but the good news is the water temperature in the area has risen considerably over the past few days to 24 degrees.
3/3/05 Animal Updates:
Snorty
Snorty
was observed passing Hontoon State Park around 2pm on 2/24.
It could not be determined if he was with another animal at that time.
By 7:30pm on 2/25, Snorty had swam over nine miles away from Blue Spring and was located via ARGOS in the Norris Dead River near Blue Peter Lake.
He returned to Blue Spring on 2/26 and was observed by park staff with
other animals near the mouth of the run the morning of 2/27.
He was also observed at the mouth of the spring on 3/1 with several other
animals.
Snorty
was observed socializing with other animals on 3/2 and around 1pm he followed
three animals out of Blue Spring to an ox bow in the river just north of Blue Spring. He was observed going
under floating vegetation but we could not confirm he was eating at that time.
We returned later in the afternoon and confirmed he was feeding on
pennywort vegetation. He was surrounded by at least five other animals exhibiting
the same behavior. At 6:20pm, Wayne
Hartley at Blue Spring reported seeing Snorty in the spring run, bottom resting
next to Scarface.
Scarface
Scarface
was observed in the southern portion of Hontoon Dead River on 2/25 slowly
traveling north along the vegetation edge.
She didn’t travel far and was located back in the southern portion of
Hontoon Dead River on 2/26. Scarface
was observed alone on 3/1 in a small portion of Snake Creek surrounded by large
amounts of vegetation, swimming in tight circles (i.e. pacing behavior).
She did not appear to be entangled and she did have an open area to
obtain air. The water temperature
was 15 degrees Celsius and her breathing rate was one every 1 ½ to 2 minutes.
No animals were seen anywhere near her vicinity but a large number
of manatees were noted at Blue Spring. Needless
to say, we became very concerned and notified SeaWorld and USFWS.
On 3/2, Scarface was again observed in Snake Creek pacing and the water
temperature was still 15 Celsius. We
notified SeaWorld and USFWS about the situation and requested to relocate
Scarface back to Blue Spring. The
reasons for the concern were as follows: Five
days without showing any signs of moving out of the area; extreme cold water
with continued cold weather conditions for the next week; no other wild animals
in the area; large numbers of manatees being seen at Blue Spring (even Snorty
moved back to the spring); pacing behavior indicating stress; potential that
continued pacing behavior might reduce overall body condition/health; simple
fact that she had not moved back to the spring when it got cold indicated that
she had not learned where to go for warmth.
All agreed it would be a good time to relocate her now instead of waiting
for her to use up fat reserves or risk putting her into a further compromised
health condition. Our hope was that upon this release into Blue Spring, the
increased number of manatees in the run would increase her chances of learning
the importance of the area for warm water and how to navigate the waterways.
Thus,
Scarface was captured and relocated to Blue Spring late 3/2.
The capture went very smoothly with minimal resistance.
Blood was obtained prior to release by SeaWorld’s veterinarian Mike
Walsh. Upon release, Scarface was
observed milling around, socializing periodically.
She quickly began to bottom rest with an occasional wild manatee waking
her up due to nuzzling or tag tugging. Pacing
behavior was not observed. At
620pm, Wayne Hartley at Blue Spring reported seeing Snorty in the spring run
bottom resting next to Scarface. Scarface
was observed bottom resting in Blue Spring most of the day on 3/3 along side
other animals. She was also
observed socializing for brief periods of time.
Breathing rate was normal for a resting animal.
Thank you to all the SeaWorld crew for responding so quickly. As the public at Blue Spring watching the relocation yelled after the release of Scarface, “Way to go SeaWorld”.
