Field Notes:
2/25/07:
Has not moved out of Blue Spring during our visual observations or according to the GPS readings. But he was very social during our observation periods.
3/1/07:
Dundee made his move out of Blue Spring late on Monday 2/26/07. He moved south and was at the entrance to Wekiva River today 3/1/07.
4/12/07:
James recovered Dundee ’s tag at 1952 hours on April 11 -- the tether was broken at the belt. He found it at the home of an Altamonte Springs resident, in the back of the resident’s car, wrapped in a blanket and towel and under 2 heavy jackets. The man told James that he had not had a chance to call --- and turned the tag over with a smile. He and a friend had found the tag in Lake Monroe , east of the marina, along the river walk on April 9 at about 1800 hours. He e-mailed a map of the area to James.
5/07/07:
On April 5, Dundee was found approximately 1/2 mile into the Lower Wekiva River off Marker 96 of the St. John 's River . He was observed from 12:05 to 1:35 -- he was with one other adult and mostly milled, fed for almost 15 minutes on what looked like gator weed, and then bottom rested for approx. 20 minutes until he and his companion began traveling to the St. John 's River. They traveled for approx. 20 minutes until they reached the SJR and headed north. A visual of Dundee while socializing at the boat for a short time showed that he appeared to be in good shape, w/ no new scars or marks detected.
On April 11, James recovered Dundee ’s tag w/ the tether broken at the belt. It was at the home of an Altamonte Springs resident, in the back of the resident’s car -- the man told James that he had not had a chance to call. He and a friend had found the tag in Lake Monroe , east of the marina.
On April 13—At Lake Monroe, under the I-4 bridge and north along the shore line, about 500 yards north of the bridge in a small un-named cove with 5 feet of water on the left, James found Dundee with 8 and 1 inside the cove by the second island strip--the entire area is about 1 acre--they were milling with one short time of feeding. The closest James was able to approach him was approximately 15 to 20 feet. He spent over an hour trying to wait him out / approach him. All the animals were active and steady moving with several large gators were within 75 feet but none ever approached.
On April 14, James went to the same area as Friday and found Dundee still milling and cavorting with 8 + 1. He tried to pick Dundee out of the group to attempt a re-tag – unfortunately, there was 1 fishing boat moving around the area with a trolling motor. Then an airboat with a driver and 4 bow hunters came into the area and continued running around the edge of the banks and thru the grasses where the manatees were milling. He waited another 30 minutes for the boater to leave but he was still churning the water so he left with the idea to return later in the afternoon when it was quieter but as thunder storms formed about 6pm, he wasn’t able to go back out.
We are presently attempting to locate this individual for re-tag.
6/14/07:
On May 25, a park ranger at Blue Spring State Park said a park guest reported a manatee with no tag and something yellow around the tail. After checking, she called James Wilkinson , reporting that Dundee was in the spring run. Two park rangers went into the water to keep Dundee from leaving the springs. James called WT volunteer Adella Squires, who headed for home, gathered tracking gear, tag and tether and went to the park. By the time James arrived, Adella was getting the tag turned on, and by the time he had changed into swim gear she had the tag ready. They James went into the water with 2 Park Rangers and the tag. Diane said she had a good chance of re-tagging him, he was hanging around her. James gave her the tag and she had him tagged within 3 minutes. Thanks to all, Dundee is back on line. The tag is clipped onto the belt–and we have had trouble w/ this type of clip holding for long durations of time when clipped to a belt with more than three inches of webbing exposed. A capture in the near future to put a more permanent tether on would be advised if personnel are available. exchange w/ a proper type of tether on him. When we left Dundee , he was milling in the swim area.
On May 26, received a report from the park ranger at Blue Springs that Dundee came into the spring run about 0845. When James Wilkinson arrived, he was gone. The ranger reported he was with one other animal when he came into the spring that morning.
7/3/07:
Dundee's tag, tether and clip were recovered entangled in a mass of hydrilla in Lake Woodruff on 7/3/07. The mass was approximately 6 x 8 feet wide and about 5 feet deep. Lake Woodruff is known for having large growths of underwater vegetation this time of year so this event was not surprising. We have had tag loss in this area due to vegetation entanglement for Dundee (1st time), Snorty and Turtle. We actually were watching satellite locations closely in fear this was going to happen again when we noticed he had moved into Lake Woodruff on Sunday morning. By Monday, his tag had not updated for 24 hours which was very unusual for Dundee's tag, so we were suspicious the tag was underwater or had been damaged.
I was very shocked we did not find the belt attached to the tether since in our experience, this type of large entanglement has resulted in belts breaking. We were not able to find Dundee in the area which was odd. We found a very large group of manatees in the south portion of the lake, and a few of these animals had been seen with Dundee last week. We were suspicious that maybe his belt did come off and was in the mud not allowing us to relocate it. This would explain how the clip came off the webbing in the mass of vegetation. Unfortunately when an animal is in the mud in Lake Woodruff, we usually cannot pick up the VHF belt signal until the animal comes up for air and is near the surface or when we are extremely close to the animal. We plan to do some thorough transect searches around the last GPS locations and where the tag was recovered. But until we have investigated further, we will go with Dundee's clip to the belt worked its way off and he still has his belt....thus we will continue our search efforts to relocate him.
6/15/07 – 9/17/07:
Dundee ranged from Lake Woodruff to Blue Spring and then back up to Lake Dexter . On 6/15/07 , Dundee was seen fast traveling with a gator following his tag. He continued with the gator about 20 feet behind him, but stopped and bottom rested once the gator broke off pursuit. Dundee had accumulated approximately 100 lbs.of hydrilla/coontail vegetation on his tag and tether on 6/19/07. Some of the vegetation was removed from his tether before he left the area.
On 7/3/07 , Dundee's tag, tether and clip were recovered entangled in a 6’ x 8’ x 5’ mass of hydrilla in Lake Woodruff . There are large growths of underwater vegetation at this time of year, and there’s been tag loss in the area before due to vegetation entanglement for Dundee (1st time), Snorty and Turtle. We did not find the belt attached to the tether, nor were we able to find Dundee in the area. We found a very large group of manatees in the south portion of the lake -- a few of these animals had been seen with Dundee the previous week. Dundee was retagged in Blue Spring on 8/6/07 . Diane Schwartz from Blue Spring State Park had called confirming that the manatee in their swim area was Dundee . Dundee swam right by Diane and she clipped onto his belt with tether and tag. He then swam by Monica Ross, turned and began to rest on the bottom. Such a good boy! A snap shackle clip was attached to the small joiner of the old tether and then the belt clip tether and tag was removed. Dundee is permanently tagged again but the belt was low on his tail. His body condition looked good but he did have fresh cuts on his tail. Dundee traveled north into Lake George soon after his retagging and then settled down in Lake Dexter on 8/29/07 . He was observed multiple times gorging out on hydrilla with other animals and was very responsive to boats. Dundee's tag was recovered on 9/10/07 in Lake Dexter . The tether broke at the weak link and the tag was entangled in a 4x5x3ft wad of hydrilla. We were able to find Dundee about 1/4 mile away from the tag recovery location and he was feeding and socializing with three other animals. Lake Dexter currently is overgrown with hydrilla and over 1/2 of the waterway is impossible to navigate through with a boat. Under these conditions it makes for a great feeding site for manatees with reduced boat traffic. But the chance for tag loss in hydrilla beds of these types are very high. Thus, we suggest to not retag Dundee and attempt to monitor him once a week until he moves out of the area. He has been noted during the past three visuals gorging out on food and has been with many other manatees with a fair amount of socialization observed. We feel pretty confident he is on a great track this go around.
10/25/07:
Dundee was reporting pacing in the swim area of Blue Spring State Park by park staff this morning. We were able to clip a temp tether/tag to his belt by 8am without changing his behavior. He looks lean and fit with a round belly. The more recent propeller scars to his tail are healing with one cut much deeper than the others. The new wound is definitely not effecting his swimming ability. Within the next hour of observation, four individual manatees at different times swam up the run and interacted with Dundee. When we left Dundee, he was socializing with one other animal near the canoe basin.
Thank you to everyone from Blue Spring for keeping an eye out for the rehab animals and being willing to help out at a moments notice!!
We are very happy to be able to get a tag back on Dundee....it will be very helpful next week for his pre-winter health assessment.
10/27/07:
Dundee's tag stopped working 5 hours after being retagged Thursday 10/25/07. We were able to find him around 1100am today just past Hontoon boat basin traveling south towards Blue Spring. At 1408, he arrived in the spring and we were able to put a new tag on him with a more permanent tagging method and remove the malfunction tag and temporary clip. The old tag appears to have stopped working due to water damage. Cause for water intrusion is currently unknown since there appears to be no damage to the canister or top of tag.
11/1/07:
Dundee was captured for his pre-winter health assessment on 11/01/07 . He was able to get out under the leads multiple times and even put a decoy in the net so he could attempt to slip away (kidding about the decoy part...sorta). The male manatee that was caught on the fourth net set was not worked up but immediately released after scar photos were taken. Dundee was caught finally caught on the fifth net set in Shell Creek just off the St. Johns.
Blood, morphometrics, ultrasound, weight and fecal were obtained. Dr. Dave Murphy of Lowry Park Zoo gave Dundee an overall condition of good, with a body score of 3. He lost 170 lbs or 13% of his weight since his release on 02/20/07 . His belly was slightly round and the skin was a bit loose. The new scars noted on his tail are healing well. Blood values are pending.

Ultrasound readings showed decreases across the board with peduncle and anus readings below normal. All girth measurements decreased but are within normal values.
Dundee ’s very loose belt was tightened and all the extra gear from retagging efforts was removed. A rub spot from the old gear was created just below the buckle on his tail and may or may not create a scar. His old tag and tether were retained (if you call old equipment from five days ago). Dundee was re-released in what appeared to be a much better condition than he was in about this time last year.
Thank you to the capture crew of SWF, LPZ, Blue Spring State Park and WT during the long rainy capture day.
11/5/07:
After Dundee's capture on Thursday, he swam all the way up to Lake Woodruff. Immediately we were not happy campers because this is where he has had two other tags come off due to entanglements in hydrilla/coontail. Surprise, surprise, by Sunday his tag was not moving much and it was anticipated the tag might be off. But before plans could be made to out tomorrow to check, Blue Spring State Park called today to let us know Dundee was in the run without a tag. We will try and retag Dundee tomorrow if possible and retrieve his tag. I think he wants to hold the record for "most retaggings".
11/6/07:
Dundee was retagged in the swim area of Blue Spring State Park on 11/6/07 without effecting his behavior. There were eight other animals in the spring and two other animals in the swim area with him. He looked just like he did on Thursday except his belt has been pulled back down again...ugh.
His tag was recovered in Lake Woodruff under a mass of coontail with a dash of hydrilla and bleeding hearts. The mass was larger than his last entanglement and it took me over 45 minutes to dig out his tag. So what I propose is if the boy goes back up to Lake Woodruff or Lake Dexter this winter and sheds another tag, we do not retag him until just before the end of winter. Of course, we can retag him if any concerns arise.
There was an unconfirmed report of a belted animal in the spring without a tag this afternoon so maybe Turtle, Una or one of our MIA animals ventured in. I refuse to think it might be Dundee.
11/26/07:
Dundee was captured on 11/26/07 in The Lagoon located just south of Blue Spring. This was the third capture attempt to bring him back into captivity to determine the cause for vomiting/regurgitation (v/r). Even though the frequency of v/r episodes did decrease after 11/21/07, WT volunteers and staff continued to see 3-4 episodes of v/r each morning during the three hour visual period.
The first capture attempt day was on Thanksgiving. They were eventually successful in getting him but he was also successful of rolling out of the stretcher and off the boat. A transport vehicle could not be secured for Friday so the second capture attempt day was Saturday. Dundee was out in the river under vegetation with other animals and reported feeding with the other animals on Saturday. He was difficult to separate but after several net sets he eventually ended up back in the spring run, all the way up to the boil. The capture was called due to the lateness of the day and the lack of Dundee's willingness to leave the boil. The next capture day was set for Monday so fewer wild animals would be affected in the spring run and so there would be less boater interaction during the capture boat net sets. Dundee was located out of the spring run early Monday morning and was noted socializing with other animals in The Lagoon just south of Blue Spring. He was later alone milling around under and around vegetation but feeding could not be confirmed. He was captured on the first net set and did a lot of flipping once on the boat. His respirations were observed to be raspy and even a gurgle was heard while he they were in route to the transport vehicle. The decision was made on site to transport him to the closest facility based on the "odd" respiration sounds. Currently, Dundee is at SeaWorld of Florida.
I cannot thank everyone enough for all their efforts to get Dundee back in for medical attention.
1/8/08:
Dundee was released on 1/8/8 at 1147 into Blue Spring....again :)
There were eighty-one animals in the spring run in the morning and
over thirty present at the time of the release. He socialized most
of the day with the females and swam up to the boil twice during the
afternoon. Right before night fall, Dundee began to rest with one
other animal after a bout of pacing behavior around the swim
area. Ah, back to old habits :)
Below you will find the new measurements. Thank you to Blue Spring
for making the transition into the water easy and SeaWorld of Florida
for all your efforts while Dundee was in your care. Lets
now keep our fingers crossed the boy keeps his tag on and swims a
straight line through the end of March (crossing your toes too may not
be a bad idea).

3/11/08:
Dundee finally moved out of Blue Spring State Park on 2/15/08 when
the river temp reached 20C. We had begun to get concerned
because he was becoming more stagnant with less pacing
behavior with obvious growths of algae on his back along with the
beginning appearance of a concave stomach. He traveled south
and arrived in Lake Monroe on 2/19/08 and was observed intensely feeding
alone in Smokehouse Cove on 2/25/08. Dundee returned to
Blue Spring on 2/28/08 with a slightly round belly and then headed back
out on 3/5 down to Lake Monroe when the river temp had risen to 20C.
It appeared like he was going to return to Blue Spring on 3/10/08 but he
turned around and headed back into Lake Monroe.
4/03/08:
Dundee was not captured
today. Five deployments of the net were made and three were
completed with him inside until he worked the lead lines and got out.
Unfortunately his response to the capture boat was to swim at a very
fast rate away from the boat not letting the tag come up much. And
when I say fast, I mean fast and at a sustained rate too! After
two and a half hours of pursuit, the capture was called off due to the
difficulty in catching him, the potential stress he might be
experiencing and the potential effects that might occur if
we were able to capture him. Dr. David Murphy of Tampa's Lowry
Park Zoo gave the approval to not attempt another capture and to call
his adaptation to the wild a success. We will attempt to cut off
all his gear the next time we find him resting. A big golf clap
for Dundee you did it! Now stay still for your belt
removal. :)
4/11/08:
Dundee would not let us get within 50 feet of him yesterday to attempt
an equipment removal.
4/28/08:
Since Dundee's capture attempt we have seen a drastic change in
his behavior. The day of his capture we had tried to
approach him to cut off his equipment. He was skittish but
nothing like he is now. He begins to travel when any
boat gets within 300ft of him. Dundee has also become
very stagnant and has remained in the same .75 mile area of Lake
Monroe alone for the past ten days. Unfortunately based on experience,
when we have seen stagnant behavior with very flighty response to
boats, we have discovered the animal has been recently hit by a
boat. So we have spent three days over the past two
weeks attempting to float closer to Dundee so a swimmer
can obtain a body condition visual and cut off his
belt. But we have only been able to get within 60 feet of
him with a swimmer before he darts away. We will continue
attempts to cut his equipment free once we confirm his body
condition. We anticipate it may take a couple more
weeks though before he will allow a swimmer to get close enough.
Thus we are only attempting approaches once a week and hoping the
tag's batteries stay strong for another month.
5/8/08:
Last week, Dundee finally let us get closer to him by boat and
eventually by swimmer but he would immediately swim away if
detected. His movement around the Lake Monroe
area increased, his extreme flight response to boats in the area
decreased and he had begun to socialize with other manatees
again. Thus, we were beginning to feel better about his
condition from a suspected boat strike. It was also
determined that our best option to getting close to him was when he
was resting. Unfortunately Dundee's behavior pattern
indicated he was probably resting during the late afternoon to
early evening, which is when we always had to depart to get
our boat back to the park before closing. Arrangements
were made to keep our boat at a local marina so we could do late afternoon
visuals.
On 5/07/08, Dundee was found surface resting with two other
manatees in Woodruff Creek. A side note, one of the
manatees was Una :) We really wanted to get a good
look at Dundee's body to confirm if his recent behavior change
was due to receiving a boat strike. We confirmed no new
marks were located between his head to mid-trunk but a
white shadow was apparent on his lower right side. We
returned on 5/08/08 and Dundee was resting in three feet of
water in Woodruff Creek with five other manatees. The
swimmer was able to get close to him before the other
manatees moved to intercept which woke Dundee up. He
responded in his old Dundee way by circling the swimmer and
then going about his way very slowly. Water clarity was
again about one foot but a white hazy area was again
identified on his right side. There is no possibility it
could have been sand on his body so we conclude the shadow was
a new scar. Dundee had minimal response to his belt
being removed. He slowly swam off into the dark water
towards the direction of the other manatees.
It has been a long road in Dundee's adaptation but we can
proudly say he is a success!
Thank you to everyone over the years who cared for his well
being and assisted with our tracking efforts.
6/2/08:
Some of you may not know but Dundee showed up at Blue Spring on 5/28/08
with a boat strike and an algae covered back. He also had
longitudinal folds in his stomach. FWC organized a capture
crew with SWF but they were not able to catch the elusive
Dundee. If Dundee comes back to Blue Spring
again, WT will attempt to free belt to assist with capture
efforts.
