“Over here” shouted the snorkeller to her dive buddy. They were in fifteen feet of clear
blue water and she was diving down to pull a small green sea turtle from the capture
net to bring it safely to the surface. Two hundred yards away the catch boat tender
heard the shout and throttled up the engine bringing the boat directly towards the pair
of swimmers and their ‘charge’. Together the team quickly prepared to pull the turtle
from the water to place it carefully in the boat. Ordinarily, this was a non-event for the
Bermuda Turtle Project. It was not uncommon to get multiple turtles on one ‘set’ of the
net which then had to be tagged, physically examined, weighed, measured and blood
sampled for genetic work. However, in this instance, it was immediately noted that the
turtle had a problem that had potentially serious implications for Bermuda.
During the 1980s a previously described but uncommon disease of sea turtles started
to increase in prevalence in both Florida and Hawaii, to the point that more than fifty
percent of certain populations were affected. The disease manifested itself by multiple
benign skin tumours affecting the
eyes, skin and internal organs of
the turtles. Turtles with

Longtail Rehabilitation:
An Intern’s Perspective
Having grown up in New England, when
someone mentions seabirds I
think of the spoiled, badtempered gulls that
stalk the shores of
the East Coast.
In fact, one
of my most
poignant
childhood
memories
involves
watching
helplessly
as one
of these
aggresive birds
stole my two-yearold brother’s entire
hotdog right out of his
hands while he tried to feed the gull
some bread. I still remember the shocked look on
his chubby face as he experienced his first betrayal.
Here in Bermuda, the iconic longtail provides a far
more graceful and beautiful image of a seabird.
As head aquarist Patrick Talbot’s intern, I’ve had
the opportunity to work closely with a few of these
birds as they arrived at the BAMZ doorstep for
rehabilitation.
The research programme and rehabilitation of whitetailed tropicbirds are two of the less visible yet highly
successful functions of the Bermuda Aquarium and
Zoo. The Bermuda Longtail Project, organized and
implemented by Patrick, involves valuable research
on the breeding success of the longtail, about which
not much is known. The rehabilitation of injured
or fledgling longtails (that have prematurely left the
nest) supplements this research, as well as provides
the opportunity for banding and tracking the birds.
4
Patrick has amassed a large quantity of data which
spans several years and involves over three hundred
nests. He regularly risks life and limb in order to
collect this data due to the location of these nests,
often deep in crumbly limestone cliff cavities.
However, back at BAMZ, I regularly risk the wellbeing of my fingers as I attempt to weigh,
measure, and feed the sometimes
ferocious rehab chicks.
Twice a day I take a
deep breath and
sneak my hand
into our
makeshift
nests
(usually
large
plastic
boxes
filled with
sand), and
attempt to
scoop the baby
longtail into my
hand before it can whip
its head around and close its
beak onto the fleshiest parts of my
fingers. If this doesn’t work, I can try the less elegant
(and less used) strategy of pinning the bird down
with one hand and shoving my other hand underneath
it while the whole Aquarium echoes with ear-splitting
screeches.
Once I have the longtail securely in my hands, the
next challenge necessitates that I make the bird sit
still on the scale while I take a weight measurement
using an archaic triple-beam scale. Some of the
calmer chicks, often the veterans, will sit and chirp
amiably without supervision while I take their
measurements and clean their nests. However, the
newcomer or the rare ‘fiend’ will scream and flap
its wings tirelessly while I try not to lose my grip,
creating a cloud of dust and mites. Once in a while,
a bird will escape its caretaker and flap around
the Aquarium, sometimes even landing in a tank.
Naturally, this results in widespread terror among our
“To inspire appreciation and care of island environments”
aquarium news
fish. Next, I feed the chicks, which goes smoothly enough when the chicks are willing to eat. But when a chick
refuses to eat and runs the risk of starvation, I have the job of grabbing its beak and forcing the squid down its
throat. You can imagine how this goes over.
However, once a chick has recovered and the
time comes for it to be released into the wild, the
sense of satisfaction I feel seems worth all the
flesh missing from my fingers. We take the fullyfledged longtail to the cliffs of Nonsuch Island,
hold it facing the sea, and impart some final words
of encouragement. At this moment, the chick has
its first view of the vast ocean; it flaps its wings in
anticipation and then launches into the blue. Some
end up back in the ocean…so we keep them for a
few more days and then try again, but most soar
into the sky and
disappear.
Like humans, longtails love
calimari for dinner!
The Longtail
Project gives a
second chance to
birds that might
otherwise drown,
and helps increase
the population. In
this way, the Project
allows Patrick,
the BAMZ staff,
and the army of
interns like me
to contribute to the success of these
beautiful yet threatened birds, ensuring
their continuing status as Bermuda’s
avian icon.

Green darner wave
This summer there were two
waves of the green darner (Anax
junius) in Bermuda – the first
on August 14 and 15 and the
second on September 1 and 2,
both following several windy
days. I was privileged to see
them flying over Tobacco Bay,
the St. George’s
Golf Course
and around
my house.
There were so
many of them, and
they are quite large
(from 2.5 to 3.3 inches
in length), that they looked
like a large flock of tiny birds.
I knew that dragonflies and
damselflies migrated through
Bermuda but I had never
seen anything like this
before! And I wasn’t
alone; reports of
large numbers
of dragonflies
came in from
one end of
the island
to the
other!
In the local literature
there are several
mentions of waves
of dragonflies. Dr.
Walwyn Hughes
reported influxes of
two species in August, 1964,
and the globe-skimmer (Pantala
flaveiscens) in September 1971,
following the passage of a weak
cold front, and David Wingate
wrote of an influx after Hurricane
Felix in August, 1995.
6
There is much general information
available about dragonflies and
the green darner, but for the local
slant on the phenomenon, I turned
to David Wingate:
“Green darners are one of the
largest migratory dragonflies
in North America and, along
with about five other species,
they occur in Bermuda as
both fall* and spring
migrants but
usually,
distributed over Bermuda but
they tend to cluster in certain
areas, presumably where they are
getting small eye flies or other
insects, possibly mosquitoes.
Certainly they are well known to
eat things like
that but there
are a lot of other
insects they could
get, usually
insects
that are too
small for us
to see.
mostly
in the fall at
the end of the
summer. Their
occurrences in waves
following cold fronts is
the result of them being
blown to Bermuda in the
cold northwest or northeast
winds after a cold front has come
through in the fall and suddenly,
either over marshes or hilltops
you will see large clusters of
them, up to one hundred to two
hundred at a time – buzzing
around in quite concentrated
groups. They are not universally
The green darners will
mate and lay eggs in the
freshwater ponds** as they

and then in a few days they
are all gone. In the fall we’ll
sometimes get a hatch of the
green darners but by the winter
they also have migrated south.
In that way, they seem to be like

population; they breed as they
move south and then subsequent
generations keep moving south.
These waves are spectacular
things – there will be no
dragonflies and all of a sudden
there will be thousands all over
the island. The two waves so far
this fall* struck me as the largest
influxes of the green darner
that I have seen in many a year.
That second one was definitely

the largest influx of that species
I have even seen. I have seen
larger flights of the wandering
glider (Pantala flaveiscens) but
green darner….you usually see
a fair number but not hundreds.
I was at Fort Scaur that first
weekend in September and I
estimated, conservatively, two
hundred and fifty to three hundred
just on that hilltop but it could
have been thousands.
The saddlebag dragonflies are two
other species that occur regularly
in Bermuda but in smaller
numbers. You usually only find
them over the freshwater ponds
where they can concentrate. They
are easily recognized - they have
either red patches on the base of
the hind wing or black patches
on the base of the hind wing.
The black saddlebags (Tramea
lacerata) and the red saddlebags
(Tramea carolina) which are
much less common, occur in
waves – and usually in the bigger
waves of dragonflies you will see
a few of those too.”

* The fall migration refers to
a time frame when birds are
migrating south. It usually
begins in July with the
shorebirds and continues in
August with most other species.
** Dragonflies and their nymphs
contribute to a pond’s
biodiversity where they are
voracious predators of other
animals and, in turn, are prey
for things like the green heron
and other species of heron too.

BAMZ Library – Fully Automated!
Over the past twelve months the library staff and our
dedicated volunteer Ken Morris have been working tirelessly
to transfer all of our books from our old card catalogue
system to our electronic catalogue. Our electronic catalogue
has been in existence for a number of years but only books
purchased after 1994 had been added.
We decided it would be well worth
the time and effort required to
have a comprehensive, searchable
electronic book database in the
library. We knew this project was
going to take a great number of
hours as
there were
over 2500
books to
be added,
so we
asked our
long-time
volunteer
Ken hard at work
Ken Morris
if he would
be willing
to help us. Ken, as always, was keen to help in any way he
could and we decided he would dedicate his volunteer hours
exclusively to the project.
Now, here we are twelve months on and the project is
complete. We can now search for books by subject, title,
author or whatever little information we have, at the touch
of a button. Best of all, we are able to provide a quicker and
more efficient service to our patrons.
Thanks again to Ken for his dedication to such a monotonous
task and for donating so many volunteer hours to this project.
Also, thank you to our assistant librarian, Margaret Emmott,
for fitting an additional project into her busy schedule!

GALAPAGOS TORTOISES
Galapagos tortoises (Geochelone nigra) originate on the Pacific islands of the Galapagos Archipelago and are one
of the largest living tortoise species in the world. These tortoises can be further broken down into probably thirteen
species of tortoise of which only
eleven survive today. The shell or
carapace of a tortoise is formed of
bone with the external plates fused
to the skeleton of the reptile to
form a strong defensive structure.
A tortoise that feels threatened will
retract its head and pull back its
front legs to put the large scales
on the legs as a shield against the
outside world.
The carapace shape of the tortoises
corresponds to the habitat they are
found in. Larger islands with more
wet highlands and lush vegetation
near the ground have tortoises with
‘dome-back’ shells such as the ones
at BAMZ. These tortoises have
restricted upward head movement
due to shorter necks, they also have
shorter limbs. They are, however,
the larger and heavier subspecies of
BAMZ tortoises, Crooked Nose and Sally, socializing with one another
Galapagos tortoise. Smaller, drier
islands tend to have tortoises with
‘saddle-back’ shells comprising of a
carapace elevated above the neck and flared around the back legs, they also
have longer and thinner limbs. The tortoises do not have to be of either
type as there are intermediate variations with characteristics of both these
extremes. In all species the male has a concave undershell to aide in mating
and is larger than a female of comparable age.
Tortoises are herbivores with a diet in the wild consisting of cactus,
grasses, vines, leaves, and fruit. Some of their diet consists of plants
that are toxic to humans such as the poison apple, yet it is one of their
favourites along with fresh young grass and an endemic guava. Most of the
moisture the tortoises require comes from dew and sap of the foods they
eat, but they can survive long periods without liquids by breaking down
the body fats already in their system. Although capable of withstanding
drought tortoises seem to enjoy drinking and wallowing in water. Tortoises
being reptiles are cold-blooded and usually bask for two hours after
dawn gaining energy through their shell before being active for eight to
nine hours. They tend to sleep in mud wallows, pools or a pallet (a snug
depression in soft ground or dense brush) for up to sixteen hours.

Until the new veterinary clinic is built as part of the
new Madagascar building we need to take our
animals off site for vet check-ups. To take Crooked
Nose to the vets he must be taken to the eastern end
of the facility and then loaded on a truck. Some of
the visitors to BAMZ have been surprised to observe
our method of achieving this. Imagine strolling
along the paths at the Zoo and being confronted by a
tortoise on a cart (surrounded by his entourage) being
pulled and pushed at high speed (for a tortoise) to his
destination. Lifting Crooked Nose onto a truck is the
simplest part of the process as long as a truck with
a lift gate is used. All we have to do is make sure he
doesn’t move while he goes up and then put him in
the bed of the truck. During the ride a keeper stays
in the back with him to ensure nothing untoward
happens such as him trying to climb out.

remove him from the vehicle and then to move him

It’s hard to imagine that seven weeks of Aqua Camp
went by so quickly; but what a wonderful seven
weeks it was. More than five hundred students
attended Aqua Camp this
summer and judging by
all of the smiles and the
eight year old intellectual
scientific conversations,
it was obvious that much
was learned and a good
time was had by all. This
year’s students ranged in age
from four through ten and
they studied different topics
including animal behaviours,
reptiles, whales and Bermuda’s
unique habitats. For some of the
students it was the first time they
had snorkeled, come face to face
with an iguana or touched a ball
python, while others preferred to
simply day-dream as Spike the barracuda and Darth
Vader the black grouper swam by in the North Rock
tank. At the end of each week students walked away
with great pride knowing they had numerous art
projects to show off at home.

education
Our approach to teaching
in our Aqua Camp programme
is quite simple; hands on, hands on,
hands on! Under the watchful eye of
experienced teachers, our students have
the opportunity to learn for themselves
and to reinforce and clarify ideas they may
have. It is always rewarding to see students
get excited about personal discoveries
they have made; ones they will not easily
forget. Our job is simply to provide a rich
environment in which these discoveries can
be made and with the help of our BAMZ bus
and Bermuda’s incredible natural beauty, I can say with
certainty that many children were “inspired to appreciate
and care for their island environment”.
Thank you for supporting our Aqua Camp this summer
and for giving us the opportunity to inspire the next
generations to appreciate and care for Bermuda.

Let’s Get Back to the Tap
We all know that we should drink at least eight
glasses of water each day but did you know
how harmful it is to the
environment for us to
drink our water from
plastic bottles?
We buy more bottled water
than any other drink
except for soda.
The bottled water
market is booming.
Americans drank
more than 8.25
billion gallons
of bottled
water in
2006 that’s an
increase of
9.5% on the
previous year,
spending nearly
$11 billion in the process, all for a product that is
virtually free. It’s highly likely that bottled water is
no safer or cleaner than our home tap water!
Bottled water puts a strain on our wallets and the
environment. Making the plastic for the bottles and
transporting the finished product over hundreds or
thousands of miles consumes energy, pollutes the
environment, and contributes to global warming. A
2006 Earth Policy Institute study found that the UK
bottled water industry generates about 30,000 tons of
carbon dioxide annually, that’s the same as the energy
consumption of 6,000 homes per year. If you have to,
buy water bottled in Bermuda.
Many people believe that by re-using their plastic
water bottles they are reducing the impact on the
environment. This may be true but the plastic used
to make bottles can pose a contamination threat
if they are re-used. The most common resin used
in disposable bottles is called #1 polyethylene
terephthalate (PET or PETE). If these bottles are
reused, they can leach chemicals such as DEHA, a
known carcinogen, and benzyl butyl phthalate (BBP),
a potential hormone disrupter.
Plastic re-usable bottles don’t appear to be a safer
option. There is an ongoing debate over the safety
of bisphenol A (BPA) which is a hormone-disrupting
chemical that can leach out of the #7 polycarbonate
plastic used to make a variety of re-usable plastic
bottles. Stainless steel or lined aluminium bottles are
recommended as the safest receptacles for carrying
tap water and other beverages.
In Bermuda, many people do not trust the cleanliness
of their tank water. If tanks are maintained properly
there should be no problems. It’s a good idea to
invest in a filtration system. Water filtration systems
are relatively inexpensive and are available in most
hardware stores on the island.
By committing to tap water over bottled water you’ll
be saving money, looking after your health, and doing
a little bit more towards saving the environment.

In Bermuda we have no facility for recycling plastic
so all our plastic bottles that we throw in the trash go
straight to the incinerator polluting our environment
even more.

Mark those Berry-producing, Invasive
Brazil a.k.a. Mexican Pepper Trees for Removal
Pepper trees are either male or female, and although both
produce flowers, only female trees produce the berries that
appear in November/December. Therefore it’s a great time
to mark those particular trees for removal, as it will be
effective in greatly reducing the number of seedlings.
You can treat freshly cut stumps of larger peppers with a
herbicide such as Roundup™ mixed with diesel oil.
