ABSTRACT
This is a preliminary and general overview of the Workshop on the Research and Management of
Solitary, Sociable Odontocetes, held on 10 December 2005 as part of the 16th Biennial Conference on the
Biology of Marine Mammals in San Diego, California. The overall goal of this international workshop
was to increase the effectiveness of individuals, organizations, and agencies working to improve research
and management of these animals by a) sharing and compiling existing information, b) identifying and
developing policy, management, and research recommendations and c) improving the exchange of
information, communication, coordination, and collaboration between all involved parties. Since the
activities initiated from this workshop are still in progress, this paper represents an on-going effort and
serves only as an initial overview of objectives, background, action items, and recommendations that are
continuing to be consolidated. Meeting objectives were defined prior to the workshop as follows: (1)
Identify the most serious dangers to the safety of solitary cetaceans and humans, (2) Identify what aspects
of protecting solitaries and humans (through management/guidelines, policy, and research): a) have
proven to be the most and least successful at mitigating these dangers (dependent upon species and
circumstances), b) have not yet been explored but show the most promise in exploring, (3) Evaluate the
effects of interacting with solitaries as part of recreation and management, (4) Identify the origin of
solitaries, and (5) Identify the most important needs and recommendations for government/legal policy,
management, research, and establishing an international communications network for exchange and
dissemination of information and updates about solitaries. This workshop served as a starting point to
consolidate existing information and develop a network of interested and knowledgeable parties dedicated
to the research, welfare, and protection of solitary, sociable odontocetes and the management and research
challenges and opportunities that they provide. Overall goals that were identified at the workshop that
require subsequent action, include: (1) Publication of formal proceedings from the workshop, including
bibliography, literature review, compilation of existing guidelines and participant surveys; (2) Initiation
and development of working groups to discuss and develop action plans and more definitive
recommendations for certain aspects of solitaries management in furtherance of workshop goals and
objectives; and (3) Development of a web interface and portal to consolidate research and other
information on ‘solitary sociables’ and creation of an email list serve to connect interested parties. Since
the activities initiated from this workshop are still in progress, this paper represents an on-going effort and
serves only as an initial overview of objectives, background, action items, and recommendations that
continue to be consolidated. The Workshop Workbook for the workshop, including presentations,
bibliographies, compilation of existing guidelines created to manage solitary odontocetes, participant
surveys and other supplemental information can be found at www.wdcs.org. The upcoming Workshop
Proceedings (in progress) will also be available on this website when completed.

INTRODUCTION
This is a preliminary and general summary of the Workshop on the Research and
Management of Solitary, Sociable Odontocetes, held on 10 December 2005 as part of the
16th Biennial Conference on the Biology of Marine Mammals in San Diego, California.
This workshop was the first specifically designed to discuss these solitary cetaceans who
are becoming more frequently observed and receiving notable attention from the public,
local recreational and commercial interests, regulatory agencies, and the media (e.g,
Samuels et al. 2000, 2003; Wilke et al. 2005).
This workshop served as a starting point to consolidate existing information and develop a
network of interested parties dedicated to the welfare of ‘solitary sociables’ and the
management challenges and opportunities that they provide. Over 30 individuals from nine
countries participated in the workshop, with additional participation through an established
electronic mail list serve of other researchers and interested parties who could not attend
the workshop. Participants included a diversity of stakeholders including governmental
representatives, researchers, cetologists, ethologists, filmmakers, students, and non-
governmental organizations.
Solitary, sociable odontocetes are rarely, if ever, observed in the company of other dolphins
(Lockyer 1990). They initiate social interaction with people and sometimes form close bonds
with individuals over time, even soliciting and allowing close physical contact with boaters and
swimmers. In the past, these animals have typically been small delphinids and, most commonly,
bottlenose dolphins (Tursiops sp.) (e.g., Doak 1989; Lockyer 1990; Müller & Bossley 2002).
However, there has been a recent increase in the occurrence of other solitary sociable
odontocetes; specifically, orcas (Orcinus orca) and beluga whales (Delphinapterus leucas)
(Frohoff in press). To date, at least seventy solitary and sociable dolphins have been recorded
worldwide.
With the growing phenomenon of solitary odontocetes interacting with humans there is often an
accompanying myriad of management challenges that arise in providing for the needs of the
animals and an increasing number of people eager to interact with them (Wilke et al. 2005;
Samuels et al. 2000, 2003). This workshop provided an opportunity to share the collective
experiences with solitary whales and dolphins, and to discuss areas of both diversity and
commonality in research, management approaches, and public education and outreach. There
appear to be unique aspects to each animal and his/her circumstances, requiring tailored and
individualized responses and management approaches. However, it may be possible to identify
commonalities that link these solitaries, if not in space and time, to successful approaches to
ensure their survival and welfare in the midst of public interest and safety.
Risks to Odontocetes and Humans
Solitary, sociable odontocetes exhibit many characteristic behavioral patterns that may
result in their injury or death or increase their risk of these due to proximity to human activity. In
fact, odontocetes exhibiting the highest degree of contact with humans appear to be at the
greatest risk of injury, illness and death from humans or human activity (Frohoff 2000). In
particular, incidents in which humans intentionally or accidentally injured or killed odontocetes
SC/58/13 (2006) Page 3

were reported almost exclusively for solitary animals and animals regularly provisioned with
food. The types and nature of ‘sociable’ interactions vary widely, but are generally characterized
by cetaceans initiating or allowing close and sustained proximity to humans (swimmers, waders,
boaters or people on docks) and allowing sustained or repeated interaction (tactile, acoustic and
visual) with humans. Some of these behaviors, ranging from affiliative to aggressive,
include:
• Closely following and approaching boats;
• Intensive, repetitive and frequent exploration and manipulation of boats, motors,
propellers, cameras and other objects;
• Postural and vocal mimicry of a person’s actions or motor sounds;
• Sustained and repeated tactile contact with person(s);
• Display of sexual action, including the rubbing of genitalia against an object or person;
• Biting or attempting to bite person;
It is important to note that the incidence of solitary odontocete aggression directed towards
humans, or between humans and odontocetes, varies dependent upon the circumstances
surrounding the solitary, its environment, and species involved. The only confirmed account of a
human fatality resulting from a bottlenose dolphin occurred in Brazil when a free-ranging
solitary, sociable bottlenose dolphin was physically restrained and abused by two men. The
dolphin severely injured one man and killed the other in self-defense (Santos 1995). Although
these animals provide unique opportunities for research, their interactions with humans typically
warrant immediate, intensive, and innovative methods of management to minimize hazards to
humans and the cetaceans. These situations have been the focus of much recent deliberation and
debate among scientists, managers, and the public. Relatively few studies of these animals have
been published (but see Frohoff 2000, Frohoff et al. 2000; and Wilke et al. 2005); and even less
information is available about their management. Thus, management of these situations is often
undertaken with little knowledge of previous successes and failures involving the same or similar
species.
This workshop provided an opportunity for researchers and managers from around the world to
present new case studies and information, share video footage, and to evaluate various methods
and needs of research and management. It facilitiated discussion about the unique opportunities
and challenges that solitary, sociable odontocetes present – and how they can best be addressed.
The overall goal of this international workshop was to increase the effectiveness of
individuals, organizations, and agencies working to improve research and management of
these animals by a) sharing and compiling existing information, b) identifying and
developing policy, management, and research recommendations and c) improving the
exchange of information, communication, coordination, and collaboration between all
involved parties. Since the activities initiated from this workshop are still in progress, this
paper represents an on-going effort and serves only as an initial overview of objectives,
background, action items, and recommendations that are are continuing to be consolidated.

Summary of Discussions
Clarification of the terms “management” and “stewardship” was made at the beginning of
the workshop discussion and included the following:
• Stewardship is often part of larger management plan.
• Stewardship is typically conducted by non-government organizations (NGOs) while
management is often a function of government and regulatory agencies. Sometimes
the two can work collaboratively or the government gives authority to individuals
or NGOs.
• Managing humans versus managing a solitary cetacean are usually different
challenges and require different solutions.

by technical assistance from working group
OVERALL GOALS REQUIRING SUBSEQUENT ACTION
Because of the ambitious agenda and timeframe of this workshop (one-day), all discussions and
recommendations were not achieved. As a result, it was decided that interested parties would
form working groups for important issue areas to further recommendations from the workshop,
as well as develop tangible recommendations that will serve as tools for the research and
management of ‘solitary sociables’. These include the following:
• Publication of formal proceedings from the workshop, including bibliography,
literature review, compilation of existing guidelines and participant surveys (to be
subsequently finalized and posted on the WDCS website, www.wdcs.org)
• Development of a web interface and portal to consolidate research and other information
on solitary, sociables and creation of an email list serve to connect interested parties
• Initiation and development of working groups to discuss and develop action plans and
more definitive recommendations for certain aspects of solitaries management in
furtherance of workshop goals and objectives. The following working groups were
created:
1. Research Requirements Working Group: to identify and recommend research
needs.
2. Website Working Group: to develop web portal, initially or permanently to be
hosted by WDCS, and to serve as central location for scientific information and
exchange, resources, contact information, and other tools to be identified.
3. Guidelines Working Group: to identify recommended guidelines and
approaches to proactive and reactive ‘solitary sociables’ situations.
4. Public Outreach Working Group: to develop and standardize public outreach
regarding the content and manner in which guidelines be distributed to the
public.
SUMMARY OF PRELIMINARY WORKING GROUP DISCUSSIONS AND
RECOMMENDATIONS
To date, the following recommendations have been compiled from the working groups that
were initiated at the workshop:
“Research Requirements Working Group”
Revised Goals & Activities
SC/58/13 (2006) Page 10
10
Goals
1. To encourage the development of non invasive research projects designed to provide data
to improve the management of solitary odontocete situations (recognizing that most
management issues relate to managing humans rather than the cetaceans).
2. To encourage the development of non invasive research projects designed to investigate
why specific odontocetes have become solitary (e.g., orphaned, social companion(s) has
died, etc) and why some of these solitary odontocetes redirect their social behavior
toward humans.
3. To encourage the development of research protocols designed to maximize the collection
of data from dead solitary odontocetes.
4. To develop procedures to ensure the dissemination of information from this working
group.
5. To encourage multidisciplinary and interdisciplinary research on solitary, sociably
odontocetes.
6. To promote the integration of research and management/stewardship so that both
activities will complement and support each other.
7. To develop policies and strategies to reunite solitary cetaceans with their families when
appropriate (e.g., when a calf is separated from a known mother or natal group, or a
solitary has become geographically isolated.)
8. That baseline research is implemented at the first possible opportunity when an
odontocete is believed to be displaying human oriented social behavior.
Activities
1. Develop a data base of all known current sociable solitary odontocetes and the research
currently being undertaken on them.
2. Facilitate the establishment of an email forum to allow researchers to share experiences
and ideas in relation to sociable solitary odontocetes.
3. Develop generic protocols for the preliminary investigation of sociable solitary
odontocete situations until site and individual specific methods can be developed.
4. Provide input into the proposed solitary sociable odontocete website to be hosted by
WDCS.
5. To investigate funding opportunities for research into sociable solitary odontocetes.
“Guidelines Working Group”
Items for discussion
• The differences between female and male solitary cetaceans.
• Difficulties of cohabitation with fishermen and divers.
• Importance of guidelines to facilitate the cohabitation of fisherman/divers and solitary
cetaceans.
• “Compulsive behaviors”, such as playing with nautical material: find the appropriate
guidelines and convince people not to arouse the interest and nor to use boat material
with solitary sociable cetaceans.
• In France, there are two solitary and sociable dolphins behaving differently,
we ought to be careful to avoid confusion on the given information specific to
each dolphin.
SC/58/13 (2006) Page 11
11
• General guidelines to be as clear as possible:
o What to do when the solitary sociable cetaceans gets tangled in rope ?
o What to do when the dolphin is playing with nautical material?
Proposed Goals and Timelines
(Proposed timeline of June 2006)
• Ideas for guidelines and more support of the authorities for this summer 2006 for existing
solitary animals in different countries/region.
• Synthesis of all guidelines that we already have, to find out the common points and the
different ones (and why there are different points or opinions).
(Proposed timeline of Fall 2006)
• Language for educational outreach materials.
FORMAL WORKSHOP PROCEEDINGS
The Workshop Workbook for the workshop, including workshop presentations,
bibliographies, compilation of existing guidelines created to manage solitary odontocetes,
participant surveys and other supplemental information can be found at www.wdcs.org.
The upcoming Workshop Proceedings (in progress) will also be available on this website
when completed, and are an attempt to consolidate existing information on solitaries and
serve as a comprehensive resource for those interested in the subject. It is hoped that these
documents and the workshop upon which it is based will serve to foster additional and
improved attention and research on the management and stewardship of solitaries in the
future.
