Five secretarybird chicks at Chester Zoo have hatched for the first time in the institution’s 95-year history, a result the zoo describes as ‘a landmark breeding breakthrough that we hope will help secure the future of the endangered species’. The achievement comes at a critical moment for a bird whose wild population has fallen to as few as 6,700 individuals.
A rare result inside a struggling European population
The five chicks hatched to a pair named John and Jolene, who arrived at Chester Zoo as part of coordinated international efforts to protect one of Africa’s rarest birds of prey. Across the entire European breeding programme, only 79 birds are held, and in the past year just three other chicks have hatched at other institutions. The scale of that context gives the Chester result its weight.
‘Seeing five healthy chicks hatch in such a short space of time is an incredible achievement for everyone involved,’ said birdkeeper Jamie Cartwright-Stock.
According to BBC News, keepers spent years studying the birds’ courtship behaviour and working out the precise conditions they needed before breeding would occur. That patient groundwork, rather than fortune, explains why the hatch happened now and not sooner. ‘Our experts believe the techniques developed here in Chester could now help other conservation zoos boost breeding success across Europe,’ the zoo said.
Why secretarybird chicks at Chester Zoo matter beyond the count
The secretarybird is unlike most birds of prey. Rather than stooping from height, it hunts on foot, striding across African grasslands on long, thin legs. Its scientific name, Sagittarius serpentarius, translates roughly as ‘the archer of snakes’, a reference to its ability to kill venomous snakes by stamping on them with repeated, powerful strikes.
The species has been listed as Endangered on the IUCN Red List since 2020, according to BBC News. Numbers in the wild have declined sharply as Africa’s grasslands have been lost to agriculture and urban development. The combination of habitat loss and a slow reproductive rate makes captive breeding programmes a practical backstop while wild populations remain under pressure.
Andrew Owen, the zoo’s Head of Birds, set out what Chester intends to do with the knowledge it has gathered. ‘With five new chicks, we’re playing a leading role in the conservation of these incredible birds. By monitoring and sharing everything we learn about these chicks, we can help improve breeding success across the entire safety-net population in zoos,’ he said.
Sharing the techniques with other institutions
The immediate challenge is raising five chicks successfully, but the longer-term opportunity is the expertise Chester can now pass on. Because the European programme holds so few birds, every technique that improves hatch rates elsewhere compounds quickly across the whole population. A programme of 79 birds has almost no margin for prolonged breeding failures at any single institution.
The arrival of John and Jolene at Chester Zoo was itself a coordinated decision, made within the framework of the international conservation breeding programme rather than as an individual acquisition. That co-ordination reflects how tightly managed the species’ captive population has to be given how few birds exist.
What happens next will depend partly on how the five chicks develop and partly on how effectively Chester can document and share the conditions that made the hatch possible. The zoo has committed to doing both. The courtship study, the breeding conditions, the keeper observations accumulated over years: all of it will now feed back into a programme that, on current numbers, needs every piece of practical knowledge it can get.
