Andrew R. Halloran



Andrew R. Halloran est primatologue, conservationniste et spécialiste du bien-être animal. Cela fait plus de 25 ans qu’il travaille avec les chimpanzés dans des refuges, dans des zoos et en pleine nature. A.R. Halloran a fondé et dirige The Elgin Centre, une organisation à but non lucratif dont la finalité est d’améliorer la vie des animaux captifs. Ce centre coopère avec des zoos et des refuges. Il fournit des consultations spécialisées en vue de concevoir des stratégies de soin au meilleur coût, des programmes d’enrichissement et des protocoles de sécurité qui garantissent l’épanouissement des animaux tout en répondant aux besoins des institutions.

Par ailleurs, il a cofondé le Tonkolili Chimpanzee Project en Sierra Leone. Il s’agit d’une initiative communautaire autour de la rivière Pampana. Ce projet atténue les conflits entre humains et chimpanzés dans les paysages anthropiques au moyen de la promotion de l’agriculture durable et d’incitations économiques, ce qui réduit le nombre de chimpanzés tués, et encourage la coexistence à travers l’éducation et la préservation des habitats.

A.R. Halloran est l’auteur des livres suivants : Song of the Ape (2012, St. Martin’s Press), Lion Shaped Mountain (2021, Earth Island Journal), et Animal Curation: The Science of Care & Welfare (2025, Cambridge University Press).

Par son travail au sein de The Elgin Centre et du Tonkolili Project, A.R. Halloran concilie captivité et conservation, et défend des pratiques éthiques qui promeuvent une vie épanouie pour les chimpanzés et les autres animaux

L’espoir d’A.R. Halloran, en écrivant ce texte, est que le partage d’histoires sur les refuges pour chimpanzés lui permettra de mettre en lumière leur qualité d’individus à part entière et d’illustrer les complexités scientifiques à l’œuvre lorsqu’il s’agit de fournir de bonnes conditions de vie à cette espèce extraordinaire.

Andrew R. Halloran, Ph.D.



Andrew R. Halloran, Ph.D., is a primatologist, conservationist, and animal welfare specialist with over 25 years of experience working with chimpanzees in sanctuaries, zoos, and the wild. Halloran founded and directs The Elgin Centre, a nonprofit organization dedicated to improving the lives of captive animals. The Centre collaborates with zoos and sanctuaries, offering expert consultations to develop cost-effective care strategies, enrichment programs, and safety protocols that ensure animals thrive while meeting institutional needs.

Additionally, he co-founded the Tonkolili Chimpanzee Project in Sierra Leone, a community-based initiative along the Pampana River. The project mitigates human-chimpanzee conflicts in anthropogenic landscapes by promoting sustainable agriculture and economic incentives, reducing chimpanzee killings, and fostering coexistence through education and habitat preservation.

Halloran has authored the books Song of the Ape (2012, St. Martin’s Press), Lion Shaped Mountain (2021, Earth Island Journal), and Animal Curation: The Science of Care & Welfare (2025, Cambridge University Press).

Through his work with The Elgin Centre and the Tonkolili Project, Halloran bridges captivity and conservation, advocating for ethical practices that promote a life of thriving for chimpanzees and other animals.

In writing this piece, Halloran hopes that by sharing the stories of chimpanzee sanctuaries, he can highlight them as the individuals they are, as well as showcasing the complexities of the science of providing good welfare to such an extraordinary species.

Get to Know a Muxe Artist and Activist

A muxe woman, Peregrina Vera is a member of the Indigenous Zapotec community from the town of Juchitán in the southeast of Oaxaca state in Mexico. A skilled artisan of traditional woven clothing, Peregrina also prepares decorations for local festivals. But in addition to her artistic endeavors, she is one of the leaders of the Transformándome (“Transforming Myself”) project housed at Mexfam, a nationwide civil society organization promoting access to health, education, and advocacy of sexual and reproductive rights. The project helps educate the muxe about their rights and how they can live authentically as themselves, including acquiring identification documents that accurately portray their names and genders.

Peregrina’s activism includes documenting incidents of hate crimes against the muxe throughout the region. This is a subject she unfortunately knows all too well after she experienced a recent violent attack and robbery in which all of her work tools were stolen.

These incidents have increased as new people have moved into the region.

“Before they did nothing to us,” Peregrina explains. “Now if you’re at a party, just by seeing you, they want to attack you, they insult you, and on many occasions, the aggression changes from words to physical attacks.”

By documenting these incidents, Peregrina is helping to bring the issue of hate violence to the attention of authorities and the public. She is also working to connect members of her community through online meetings using computers acquired by the Transformándome project. All of her activism is aimed at increasing the acceptance and inclusion of her muxe community.

Una líder Muxe comparte su historia

©MEXFAM


Mujer Muxe, Peregrina Vera es miembro de la comunidad indígena Zapoteca del pueblo de Juchitán, en el sureste del estado de Oaxaca. Hábil artesana de la ropa tejida tradicional, Peregrina también prepara adornos para las fiestas locales. Pero además de sus esfuerzos artísticos, es una de las líderes de Transformándome en Mexfam, la organización nacional de planificación familiar de México. El proyecto ayuda a educar a la comunidad Muxe sobre sus derechos y sobre cómo pueden vivir auténticamente sin esconderse, incluyendo cómo obtener documentos de identidad que reflejen con exactitud sus nombres y géneros.

El activismo de Peregrina incluye la documentación de incidentes de crímenes de odio contra la comunidad Muxe en toda la región. Se trata de un tema que, por desgracia, conoce demasiado bien tras haber sufrido recientemente un ataque violento y un robo en el que le sustrajeron todas sus herramientas de trabajo.

Estos incidentes han aumentado a medida que nuevas personas se han trasladado a la región.

“Antes no nos hacían nada”, explica. “Ahora, si estás en una fiesta, solo con verte quieren agredirte, te insultan y, en muchas ocasiones, la agresión pasa de las palabras a los ataques físicos”.

Con la documentación de estos incidentes, Peregrina está ayudando a llamar la atención de las autoridades y del público sobre el problema de la violencia motivada por el odio. También está trabajando para conectar a los miembros de su comunidad a través de reuniones en línea utilizando computadoras adquiridas gracias al proyecto Transformándome. Todo su activismo busca aumentar la aceptación y la inclusión de su comunidad Muxe.
