Belfast Zoo has announced the death of two of the world’s rarest lions after 22 years together. Sisters Thheiba and Fidda, both Barbary lions, were put down on 6 March following a joint decision by the zoo’s veterinary staff. The subspecies, which formerly inhabited the mountainous regions and desert areas of North Africa spanning Morocco to Egypt, is now no longer found in nature, with only an estimated 200 individuals living in captive environments. The two lionesses were part of the EAZA Ex-Situ Program, a conservation initiative designed to preserve the Barbary lion through meticulously controlled breeding programmes. Their passing marks the death of two important figures to their subspecies’ survival, with both sisters having given birth to numerous offspring during their years at the Belfast facility.
A Lifelong Relationship Concludes in Kindness
Thheiba’s declining health in her later years prompted the tough call to euthanise both sisters together. The older lioness had begun suffering from considerable movement problems and progressive weight loss, evidence that her wellbeing was declining. Belfast Zoo’s animal care specialists faced an agonising choice: allow Thheiba to suffer, or make the humane choice to put an end to her distress. However, separating the two would have been similarly inhumane, as the sisters had lived all 22 years together and maintained an inseparable connection typical of their highly social species.
The zoo’s decision reflected a growing recognition among conservation facilities that the psychological welfare of animals is equally important to their physical health. Lions are highly social creatures, and Fidda would have experienced considerable suffering from losing her long-term mate. Zoo staff concluded that euthanising both sisters simultaneously was the most compassionate course of action, allowing them to stay together even in death. “Both lionesses will be affectionately recalled by the staff who cared for them and the thousands of visitors that adored them,” the zoo stated in their formal statement.

The Barbary Lion: From North African Wilderness to Extinction
The Barbary lion, formerly a majestic predator roaming the mountains and deserts of North Africa, exemplifies one of conservation’s most stark failures. These remarkable creatures, distinguishable from their African cousins by their impressive size and notably lengthy, dark manes that extended to their bellies, inhabited territories spanning from Morocco to Egypt. Their powerful build and commanding presence made them renowned across the region, yet by the 1960s, they had disappeared completely from the wild. Today, Thheiba and Fidda’s passing marks another chapter in the sorrowful tale of a subspecies that exists only because of human intervention and captive breeding programmes.
The Barbary lion’s extinction in the wild was not caused by natural causes but from deliberate human persecution. During the 19th century, as European settlements spread throughout North Africa, Turkish and subsequent French authorities issued bounties for killed lions to safeguard growing settlements and farm animals. These monetary rewards created a systematic extermination campaign that proved devastatingly effective. Hunters capitalised on the rewards, methodically eliminating the lions until none survived in their native habitat. What had once been a thriving population across an entire continent was reduced to nothing within a single century, a warning example of unchecked human expansion at the cost of wildlife.
Decline Throughout History and Contemporary Persistence
Today, approximately 200 Barbary lions exist exclusively in captivity, surviving solely through committed preservation work like the EAZA Ex-Situ Program. This global breeding programme represents humanity’s final opportunity to safeguard the subspecies from total extinction. Zoos across the globe, such as Belfast Zoo, participate in carefully coordinated breeding programmes intended to preserve genetic variation and avoid inbreeding within the captive population. Without these initiatives, the Barbary lion would have been reduced to merely a historical relic, remembered only in old photographs and museum specimens rather than living creatures.
Thheiba and Fidda illustrated the critical importance of these preservation initiatives. Throughout their 22 years at Belfast Zoo, both sisters contributed significantly in the continuation of their subspecies by bearing many descendants. Their long life, well surpassing the normal lifespan of wild lions, showcased the safeguarding and support offered by the zoo’s dedicated staff. Yet their story also reveals a difficult paradox: whilst breeding in captivity keeps the Barbary lion from being lost forever, it cannot recover what was lost. These animals exist in man-made settings rather than their original North African territories, a testament to both preservation achievements and human failure.
Preservation Via Breeding Programmes in Captivity
The EAZA Ex-Situ Program represents a global collaborative effort to safeguard species facing imminent extinction. By managing breeding programmes across zoos and conservation centres throughout Europe and beyond, the programme sustains genetic heterogeneity whilst mitigating the close breeding that could exacerbate the decline of the Barbary lion population. Each contributing organisation supplies essential data and resources, establishing a unified strategy that extends beyond geographic constraints. Thheiba and Fidda’s engagement in this programme underscored their importance as more than exhibition specimens; they were living ambassadors for their subspecies, their offspring carrying forward DNA that might otherwise have been lost entirely from the planet.
Belfast Zoo’s dedication to the EAZA programme demonstrates how contemporary zoos have transformed from basic animal collections into conservation powerhouses. The facility gave Thheiba and Fidda with specialised veterinary care, proper feeding, and enhanced living spaces that permitted them to live substantially longer than their counterparts in the wild would have. This extended lifespan enabled both sisters to create several generations of offspring, multiplying their role in species survival. The zoo’s decision to chronicle and distribute their journey with many thousands of yearly visitors also fulfilled an educational function, raising public awareness about conservation challenges and the essential function managed breeding plays in preventing extinction.

- Genetic diversity maintained through meticulous record-keeping and planned breeding partnerships
- Captive populations function as an insurance policy against extinction of species
The Role of Cross-Border Partnership
International partnership forms the foundation of effective species conservation in the modern era. The EAZA Ex-Situ Program demonstrates how institutions across various regions can work in concert towards a shared objective, sharing expertise, genetic information, and propagation advice. Belfast Zoo’s participation alongside centres across Europe ensured that determinations regarding Thheiba and Fidda’s husbandry and propagation were based on the shared understanding of leading zoologists and conservation specialists. This joint strategy has demonstrated highly successful, enabling the Barbary lion population to remain stable at approximately 200 individuals rather than disappearing entirely. Without such international coordination and goodwill, the subspecies would have succumbed to extinction decades ago.
Why Parting Was Not an Possibility
The choice to euthanise both Thheiba and Fidda as a pair, rather than permitting one sister to survive alone, reflects a deep understanding of lion behaviour and welfare. Lions are fundamentally social creatures that develop strong attachments, particularly amongst siblings who have spent their entire lives together. For the Barbary lion sisters, who had spent every moment of their 22 years at Belfast Zoo, separation would have constituted a form of psychological torment. Veterinarians recognised that isolating one lion after the loss of her long-term partner would cause profound suffering, transforming what should have been a compassionate end into extended pain.
The zoo’s choice emphasised the psychological welfare of both animals, acknowledging that quality of life encompasses psychological health alongside physical vitality. Thheiba’s reduced movement and loss of weight signalled the beginning of the end, yet allowing her sister to observe that deterioration and subsequently experience loneliness and grief would have been equally cruel. By making the difficult choice to euthanise both together, Belfast Zoo demonstrated that true compassion sometimes means making heartbreaking decisions that honour the bonds animals create. This method reflects modern recognition that animal wellbeing extends beyond mere survival to include emotional fulfilment and dignity.
| Aspect | Significance |
|---|---|
| Lifelong companionship | Sisters shared 22 years together, creating inseparable emotional bonds |
| Social nature of lions | Lions are highly social animals requiring companionship for psychological wellbeing |
| Grief and isolation | Surviving alone would have caused prolonged psychological suffering and distress |
| Veterinary recommendation | Professional animal care specialists advised joint euthanasia as most humane option |
This strategy to animal euthanasia, though emotionally challenging for the zoo’s staff members and visitors, represents a compassionate development in how organisations prioritise animal welfare. Rather than viewing euthanasia solely as a medical necessity for an individual animal, Belfast Zoo acknowledged the mutual connection of Thheiba and Fidda’s lives and made a decision that honoured their bond. The sisters’ legacy extends beyond their genetic contributions to Barbary lion conservation; they also demonstrated to the world that true animal care involves respecting the deep connections these magnificent creatures develop with each other.
Legacy and Future Implications
Thheiba and Fidda’s remarkable 22-year lifespan demonstrates a substantial achievement in captive conservation efforts. Their participation to the EAZA Ex-Situ Program have made an enduring legacy on Barbary lion preservation, with their descendants helping to strengthen the extremely restricted population of approximately 200 individuals living in zoos worldwide. The sisters’ genetic legacy secures that coming generations of this wild-extinct subspecies will preserve their lineage, maintaining genetic variation vital for the continued existence of the species.
Belfast Zoo’s compassionate response to the sisters’ end of life has initiated extended dialogue within the zoo sector about animal care standards and end-of-life care. The choice to put down both lionesses together, rather than separate them, encourages institutions to rethink how they manage the needs of individual animals with the psychological and emotional elements of animal relationships. This precedent may affect protocols going forward across zoos and wildlife facilities, fostering a deeper comprehension of animal worth that goes further than just physical survival to encompass emotional welfare and social connections.
