Zookeepers in Prague turn into puppeteers to save baby vultures
Bird keeper Antonín Vaidl said Thursday that when a dummy egg disappeared from the nest, it signaled to keepers that the parents were not ready to care for their two babies, despite doing so in 2022 and 2023.
The first-born is being kept in a box and fed using a puppet designed to mimic a parent bird, while another is expected to hatch in the next few days.
Vaidl said the puppet is needed to make sure the bird will be capable of breeding, which it won't if it gets used to human interaction.
He explained that the puppet doesn't have to be a perfect replica of an adult bird because the chick responds to certain signals, such as the pale orange coloration on its featherless head and neck.
Lesser yellow-headed vultures live in the wild in Latin America and Mexico. Prague Zoo is one of only three zoos in Europe that breed them.
In the past, the park successfully applied this treatment to save the critically endangered Javan green magpie and two rhinoceros hornbill chicks. The puppet-feeding technique is applicable for birds that live in pairs.
'The method has been working well,' Vaidl said. 'We'll see what happens with the vultures."

SpaceX delivers four astronauts to the International Space Station just 15 hours after launch
SpaceX delivered a fresh crew to the International Space Station on Saturday, making the trip in a quick 15 hours. The four US, Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from NASA's Kennedy Space Center. They will spend at least six months at the orbiting lab, swapping places with colleagues up there since March. SpaceX will bring those four back as early as Wednesday.
