Desertas Island Snails Bred in Captivity for First Time

December 3, 2021

Two species of Desertas Island land snails have been bred in human care for the first time ever! Behind this achievement is Chester Zoo, which is working with Bristol Zoo Gardens and the Instituto da Conservação da Natureza e das Florestas to boost the population numbers of these critically endangered species.
---
These species were thought to be extinct but were rediscovered in the Desertas Islands (Madeira, Portugal), with fewer than 300 individuals left for each species - the last of their kind!

Endangered Red-Billed Curassows Hatch at Chester Zoo

November 14, 2021

Houston Zoo's successful hatching of blue-billed curassows (see previous post) was not the only good news we are sharing today... Chester Zoo has hatched TWO red-billed curassows!

---------

Same genus as the blue-billed curassow (𝘊𝘳𝘢𝘹), the red-billed curassow is native to Brazil, and listed as "Endangered" in the IUCN Red List of Threatened Species with under 200 individuals left in the wild. Chester Zoo's new hatchlings are therefore a significant boost to the captive (insurance) population of this species.

Houston Zoo Hatches Critically Endangered Curassows

November 14, 2021

Some zoo births are extra special... Two blue-billed curassow chicks hatched at Houston Zoo - the offspring of the most genetically-valuable pair of the AZA's breeding programme for the species. One of the chicks is being hand-reared and the other parent-reared at their new Pantanal exhibit.

---------

This species is native to Colombia and listed as "Critically Endangered" in the IUCN Red List of Threatened Species, with less than 2500 individuals left in the wild.

Critically Endangered Turtles Hatch at London Zoo

November 3, 2021

Amazing news from ZSL London Zoo: Three critically endangered big-headed turtles hatched at the zoo! Back in 2018, the zoo received two male and two female big-headed turtles that had been rescued from smugglers. Thanks to the expertise of the zoo's herpetology team, one of the pairs laid eggs which resulted in three new hatchlings to boost the captive population of this species!

---------

Native to southeast Asia, this species is listed as "Critically Endangered" in the IUCN Red List of Threatened Species due to threats of hunting and the illegal pet trade. Captive breeding & reintroduction are some of the conservation actions identified.

More Eggs of Critically Endangered Loa Water Frog Laid at Zoo in Chile

August 11, 2020

A red-headed vulture chick (Sarcogyps calvus) hatched at Parco Natura Viva earlier this year - only chick of this critically endangered species to hatch in zoos world-wide. This species is rare in the wild, and difficult to study, and therefore the data and expertise obtained by this zoo is invaluable for the conservation of this species.
