INTRODUCTION
Since the mid l97Os there has been a
dramatic rise in the public interest in the veterinary treatment and rehabilitation of
wildlife casualties, and subsequently a parallel increase in the number of "Wildlife
Hospitals" and individual "carers" to complement this interest.
However, it has become evident that there is something
of a secondary wave of "casual" rescuers and carers who, by either circumstances
or design, cannot or do not demonstrate and or advocate a standard of practice that should
be considered a basic requirement for the treatment of wildlife casualties in this
"day and age".
In an attempt to alleviate some of the problems
indicated. "The Wildlife Hospitals Trust" produced a voluntary "Code of
Practice" for wildlife cares that was sanctioned by the "Royal College of
Veterinary Surgeons" and this has proved a valuable broad base for people to work to.
Some species encountered have such individual
requirements, that in order to attain an optimum level of care, specialisation and species
restriction must be considered the most beneficial approach to adopt: as in the case of
the Swan Sanctuary".
Need for a "SWAN
CODE"
"The Swan Sanctuary" is the UKs
largest and most experienced facility specifically equipped and catering for the rescue,
treatment and rehabilitation of swans. We are the only purpose built complex that can
provide "state of the art"
Veterinary facilities on site 24 hours a day and our
hospital based rescue team demonstrates a very high degree of expertise backed up with a
full range of rescue equipment, including powered inflatable boats and veterinary
ambulances. WE SINCERELY BELIEVE THAT "THE SWAN SANCTUARY" IS AT THE FOREFRONT
IN ALL ASPECTS OF SWAN CARE.
Although we are very happy to provide encouragement and
support to those who show a genuine desire and commitment to help swans in distress, the
Sanctuary feels that there is a need to maintain an acceptable standard of practice. We
would wish to see the following suggestions endorsed by those agencies relevant, after
initial consultation and agreement between ourselves and "The Queen's Swan
Marker".

RESCUES (ASSESSMENT)
Most rescues will be instigated as a result of
an initial telephone call from the public or others. To ensure that such rescues are
carried out efficiently and effectively, with minimum "fuss" and/or stress to
the bird(s) involved, the following suggested telephone procedure should be adopted:
- Answer telephone as quickly as possible (ideally before the fourth ring)
to make sure caller does not hang up in desperation.
- Clearly identify your organisation to the caller and ascertain if it a
"rescue call"
- Ask caller for a contact telephone number; this can be especially
important if the caller is in a public telephone box with limited monies: and read the
number back to the caller to quality.
- Enquire of FULL details of perceived problem, and decide if attendance is
warranted.
- If NO.. always ensure that the caller understands the reasons for your
decision, and invite them to call back if the situation changes or if the caller is still
concerned.
- If YES.. make sure you take full location details of bird(s) and how long
since last seen. Ask for the nearest distinguishing landmark (public houses are always a
good reference point).
- Ask caller about "the lay of the land" i.e. deep water, high
revetments etc., as certain situations may require specialist equipment or skills to
effect a successful rescue.
- Ask caller for a contact telephone number to use up until the rescue team
arrives, and ask them to telephone you if the situation changes in the meantime.
- Finally, read back the details to the caller (all details should be
written down as you receive them and advise caller as to what is going to happen and when.
Call them back if you need to liase with rescue team(s) and or other agencies first.

RESCUES
(OPERATIONAL) INCLUDING SAFETY
When attending a rescue situation, initial assessment is
a priority. In most cases there will be someone waiting at the scene (often the person who
reported the incident); ask for a history of what occurred, and what the person's main
concerns are. Look around to make sure that the area and the situation that you face are
safe, and take appropriate actions to maintain the same.
IT MUST BE REMEMBERED THAT SWANS OFTEN GET INTO PROBLEMS
AROUND HIGH VOLTAGE CABLES. RAILWAY LINES AND MOTORWAYS - All rescuers should make sure
that they know all the relevant safety procedures and who to contact in such an event.
Water based rescues are ALWAYS potentially dangerous,
and boat users etc should be fully competent and properly equipped. NON SWIMMERS SHOULD
NOT VENTURE ONTO OR INTO WATER UNDER ANY CIRCUMSTANCE, and should wear a life jacket when
working bankside.
IF IN DOUBT regards ANY rescue attempt. .. summon
assistance and do NOT be tempted to "give it a go" for fear of "losing
face". . you may lose much more!
Rescuers should not use any specialist equipment. i.e.
climbing gear. unless properly trained to do so
As with all wildlife casualties, the objective is to
rescue the swan(s) as quickly as possible - whilst `causing the minimum amount of distress
to the birds concerned - and the following points should be borne in mind.
Resist the temptation to use ancillary tools to capture
swans whenever possible i.e. Swan hooks' and nets - manual control of the bird(s) are the
least stressful and have less potential to cause injury to the casualty. Also many swans
are extremely wary of poles/rods and will be forewarned of your intentions to catch them.
Do NOT chase mobile birds around - the stress and
exhaustive effects of such actions could lead to the death of an already sick bird -
rather GUIDE the swan gently into a situation where it can be captured easily - a favoured
approach on open water is to gradually `push' the bird on with a boat, encouraging it to
take refuge in a reed bed etc.
Initial control of a swan can be safely effected by
catching hold of the birds neck - WITH DUE CONCERN FOR POSSIBLE NICK INJURIES APPARENT OR
OTHERWISE. - Then transfer control of the bird to its wings, holding them close to the
swan body. Do not lift the bird by its neck or legs unless forced to by local conditions.
NOTE AT THIS POINT THAT ALL SWAN
RESCUERS SHOULD HAVE BEEN TRAINED IN HANDLING TECHNIQUES BACK AT THEIR BASE BEFORE
ATTEMPTING' FIELD WORK'.

TRANSPORTATION
It is true to say
that of all potential wildlife patients, Mute swans (Cygnus olor) are the most amenable to
motorised transportation. However, a few simple guidelines are recommended.
The mobility of swans should be restricted during
transportation; they should ideally be unable to stand or "flap", and this can
be easily achieved. If both legs are uninjured, they should be lifted back and ABOVE the
swan's tail, and with the "ankles" crossed. Tie the "ankles firmly using a
wide tape with an element of "give in it (a ladies nylon stocking is ideally suited
to this purpose). The bird should then be placed in a large shopping bag or similar with
the neck protruding and the bag closed over the swan's back. (A sack with one corner cut
out will make a good makeshift bag)
The bird being fed through the hole.
In the vehicle, the bird should be placed facing
forwards or backwards - this is to allow the bird to use its head and neck to counter
balance the effects of acceleration and braking. The bird should also be prevented from
falling sideways by using pillows or a roiled up blanket to form a "nest"
If the swan is seriously ill or injured, it may not need
to be "tied". Be aware of what can happen if a casualty suddenly "comes
round" during transit, and decides to join you on the drivers seat whilst on the
motorway. It is in fact a requirement of law to make sure that animals are physically
separated from the driver of a motor vehicle.
Birds in a "poor" state may need to be covered
to prevent excess heat loss, and if collapsed the neck should be extended to facilitate a
clear airway.
Similarly, although a fresh airflow should be provided
during transit it would be a grave mistake to allow a casualty bird to become chilled by
excessive draught
DO NOT SMOKE, PLAY LOUD MUSIC, OR CARRY DOGS OR OTHER
ANIMALS WHEN TRANSPORTING WILDLIFE - unless the casualties can be contained in isolation,
i.e. behind a fixed sealed bulkhead (this does not mean the boot space of a car). Also do
not allow small children to travel with swans, they will NOT keep their fingers to
themselves and a sick bird does not need to be poked about
Be aware of leaking exhaust pipes and over full fuel
tanks both of which can cause deadly fumes to enter the vehicle (usually at the back where
your casually will be).
Do not carry any noxious or volatile substance in such a
manner as may result in contamination of your patient. Refrain from the use of aerosol
deodorants and insecticides during transit or immediately before placing a bird in the
vehicle.

TREATMENT
Any swan that is
showing signs of sickness and/or debility that has been taken into care should receive
proper veterinary attention as soon as possible. All but the minor injuries should be
subject to veterinary treatment, and unless you can be certain that the slight injury
obvious to the "lay" person is the only one. I.e. the bird was seen caught by
one small fishing hook in the leg - then examination of the bird by trained veterinary
personnel is still advised.
Minor wounds resulting from simple hook removals
"in the field" - along with other lesser cuts and grazes - should always be
thoroughly cleaned with a dilution of "Betadine" or "Hibiscrub" etc.
before re- releasing the bird. Again, get your vet to show you what to do.
When a swan is rescued with fishing line trailing from
its mouth, and from down the throat, and resistance to the gentlest of pulls is felt, then
the bird MUST be x-rayed to see if a hook or other tackle is lodged in the oesophagus. In
this case, surgical intervention by a qualified veterinary surgeon is essential.
A swan that "crash lands" on a highway etc but
shows no apparent signs of injury or distress should be taken into "quiet care
"for 24 hours so as to rule out concussion or post traumatic shock. "The Swan
Sanctuary" rescue teams have often been called out to attend birds that were put
straight back onto water by well meaning motorists and passers by who felt the bird
"looked fine" after a crash.
For all more complex treatment regimes, follow
instructions given by a qualified vet.
Swans are normally gregarious birds, and during time of
stress exhibit a sense of reassurance and security when within "sight and sound"
of their own kind. These birds should not be held in isolation and or in the facilities
available at a mixed veterinary practice, but should be transported to a specialist unit
as soon as practicable. (The Swan Sanctuary can advise and assist where necessary.)
It is too often the case that both "lay"
rescuers or indeed "vets" inexperienced in swan care, tend to assume any
"sickly swan is suffering from lead poisoning, and embark on a course of treatment
that is by nature not without risk. If anyone, veterinary surgeon or otherwise is not
fully conversant in the subject of heavy metal poisoning and subsequent treatment - then
again" The Swan Sanctuary" will be only too happy to advise and assist at any
time.

FACILITIES
Due to logistical constraints, not everyone
wishing to care for sick/injured swans will be able to maintain an exhaustive hospital
"set up". However, such constraints should be recognised by any potential carer
s. and the following suggested standards should be met and adhered to, whatever scale of
any individual unit.
Indoor and outdoor holding facilities should be
available to carers at all times, each being used whenever appropriate to the casualty
bird concerned. Any bird fit enough to be in an outdoor enclosure will require enough room
not to feel constricted and have the opportunity to behave as "normally" as
possible.
Experience has shown that an enclosure approximately
9mtrs x 6mtrs is an optimum area that will cater for most situations likely to be
encountered. Even if suddenly presented with a family group e.g. two parent birds and half
a dozen or more cygnets.
This size enclosure will accommodate a pond that should
he of the "sunken" variety and will have a surface water area of approximately
3mtrs x 3mtrs. The depth of the pond should ideally reach 1mtr when filled, and this will
allow adult
Swans to "up end" to their limit and give
Youngsters an adequate training ground.
At least one side of the pond should be sloped at such
an angle that swans and humans can easily walk in and out when the pond is partly or
wholly drained. Remember that some birds will be a bit unsteady even on level ground. If
swans have to struggle and flap to exit a drained pond, they may well damage wings and/or
rip out claws.
Swans like all water fowl are "messy' birds, and it
is vital that good drainage and cleansing facilities are installed. Drainage should be
effected from the lowest point of the pond, and should be "non-return "either to
the pond drained or other ponds on site cross contamination is always the biggest
potential threat in any hospital"
An adequate supply of fresh water should be available
for all filling and cleansing requirements, and should include a stand pipe and hose, that
provides a good water pressure.
A shelter should be provided in each enclosure, and
"bedding" of clean barley straw put down: not wood shavings as some swans have
shown a tendency to eat these, with disastrous results. Also do not use hay for bedding,
as this is often very dusty and can aggravate any respiratory problems.
If the site is fox and dog proof, the enclosure need
only have a perimeter fence some 1mtr in height, as the birds will not ordinarily be able
to fly out of such a confined space. Although Whoopers and Bewicks can be a bit more
"flighty" than the Mutes can. Obviously any fencing should be safe and kept in
good condition. Do not use mesh large enough for birds {especially curious cygnets) to get
their heads through. In addition, NEVER top fences with barbed wire or other such
materials.
Outdoor "hospital" enclosures or pens as
described above should be surfaced with concrete throughout, and if slabs are used, then
the gaps between should be "pointed". There are a lot of misconceptions relating
to the surface that water birds require to walk on. Much of the literature available will
dissuade the use of concrete and cement, but grass and soil paddocks are impossible to
clean and sterilise, and good hospital practice will eliminate any predisposition to
"bumblefoot" or other staphylococci infections.
The enclosure should be cleaned of droppings and spilled
food and hosed down at leased once daily: more often as necessary, and the pond must be
drained and hosed down at least every 48 hours: preferably daily.
Between patients, the whole of the enclosure and pond
areas should receive thorough cleaning and disinfecting; remembering to rinse completely
before refilling the pond.
Indoor holding facilities should not be cramped or
claustrophobic, and must not be draughty. The building or room should be described as
"sound and secure", and must be capable of maintaining an ambient climate in
relation to heating and ventilation; summer or winter.
ON NO ACCOUNT should paraffin heaters be used, they are
potentially dangerous in themselves, and the flumes generated can easily kill birds.
It is often the case that swans requiring indoor
confinement will need to be held in a restricted space for their own benefit and something
along the lines of a childs playpen is about the right dimensions for most
instances.
A well maintained stock of clean newspapers, blankets
and a few' pillows or cushions will be required, along with plenty of black sacks: bin
liners
Plastic washing up bowls, towels, rubber gloves and
plastic aprons are also invaluable to the swan carer and no unit will ever find that it is
over stocked with any of these items.

REHABILITATION
& RELEASE
The term rehabilitation is often heard but less
often understood. Rehabilitating any wild creature does not simply mean "letting it
go", but rather is a methodical way of checking that the patient stands the best
possible chance of re integrating with the wild population, and has a high potential for
survival.
Although swans when re released are not the kind of
birds that will rush off into the undergrowth, or fly' away into the distance never to be
seen again, there is of course no excuse for "trail and error" methods to be
employed when liberating patients.
A sound knowledge of "normal" swan behaviour
and abilities is an essential requirement of any person who is responsible for pronouncing
a bird fit for release. The swan must demonstrate that it is able to feed, swim, walk, and
preen "normally. It must inter act with other swans in an appropriate way for it's
age and sexual status, the bird should be fully flighted (unless in moult) and should be
maintaining a body weight corresponding to is size etc.
A fit bird should be fully waterproof and if recovering
from a non-waterproof condition, must have demonstrated the ability to keep itself
waterproofed whilst kept in an outdoor enclosure for a minimum of one week. Small areas of
neck plumage absent are ok i.e. postoperative sites. However, any substantial feather loss
in this area will mean retaining the bird until re grown.
The "bonding" of family groups grows stronger
and stronger in the first few months of a cygnets life; and the time differential
between taking a cygnet into care and returning it to its family can vary enormously.
However as a guide; any cygnet away from the family group for more than five days, will
have to be reared in captivity and undergo protracted rehabilitation.
NEVER keep a cygnet on its own.. if needs be. pass the
bird onto a unit that has others of the same age (approx.), not to do so would be cruel!
When an adult swan is judged fit for release, it should
ideally be returned to the water from which it originated; unless of course it would be
dangerous to do so. If this is not possible, place the bird in the nearest non breeding
flock situation to its own water, make certain that it has settled in before leaving and
arrange for someone to "keep an eye out" for several days to ensure the swan has
adjusted well, If the swan leaves the flock its original home water should be checked out,
in case the bird has returned there to face the danger that you had previously identified.
Releases should be arranged for early morning, which
gives the bird most of the daylight hours available to re settle. Postpone releases if
there are severe weather conditions or other temporary local factors: re an angling match
is taking place.
NEVER release young birds in isolation.
NEVER release a disabled bird; if non flyer, partially
sighted, or amputee
NEVER release birds on new swan free waters without
frill investigation and consultation.
NEVER release birds on private waters without
permission.
NEVER release birds onto a site where take off and/or
landing is difficult or impossible.
NEVER release birds on waters with flight paths in or
out adjacent to power lines (pylons) and/or motorways.
NEVER release where there is insufficient natural food
supply.
NEVER release if the slightest doubt enters your mind.

RINGING & MARKING
Leg ringing under the auspices of the BTO
(British Trust for Ornithology) has long been recognised as a valuable tool in the study
of bird migrations and breeding success. It is also true to say that the welfare aspects
of catching, handling, and the fitting of the rings has often been the cause of much
concern by many individuals and animal welfare groups alike.
Seminally the fitting of large plastic
"Darvik" rings to mute swans as initiated by the Edward Grey Institute of Field
Ornithology has also aided the recognition at a distance of individuals of the species.
Primarily set up as an integral part of the Institutes
studies into lead poisoning in mute swans (Cygnus olor). the need for these rings is now
seemingly defunct; apart from a residual convenience factor. and their use should be
discontinued on this count alone However, what is more worrying to the rescue and
veterinary staff at the Sanctuary, is the apparent degeneration of the materials used in
the construction of the Darvik rings; and the increase in injuries that are caused to
birds when the rings partially "shatter". It is apparent that the rings become
extremely hard and brittle with age.
With a little more investigation into our hospital
records, and in the due process of time, we feel that it may well become evident that not
only should "Darvik" ringing be discontinued, but that all birds hospitalised
should have the old rings removed as a matter of routine.
With regards to the BTO rings, injuries caused by them
are not nearly as frequent; as long as the original fitting was correct, and the ring
remains undistorted due to "snagging" or other factors.
Mute swans are generally regarded as "semi
wild" and non migratory birds, and in some (or should it be said all) cases are owned
property. Therefore, it is suggested that the BTO be asked to qualify the need for
continuing to ring mute swans "in the field".
It is of course without question that. being able to
positively identify any individual swan that has previously undergone veterinary treatment
is of great use, as many birds undergo repeated rescue/treatments during their
(hopefully) lengthy lifetime. It is our suggestion that
ring procedures be limited to pre release from hospitalisation or other "necessary'
confinement and handling in the case of mute swans.
To lesson the possibility of injury from solid rings
even further, perhaps we should be looking towards the use of numbered cable ties as
fitted to DOE registered captive raptors (birds of prey). Alternatively, research into a
rubber based "Darvik" type ring. Finally as the technology' becomes cheaper and
more refined, we may even begin to look at utilising sub cutaneous transponders
(microchips under the skin) as is currently the case with many mammal species. |
