REARING BLACK-TAILED GODWITS FROM wild-laid eggs for later release 'headstarting' in conservation parlance - is an anxiety-inducing business, as I discover on a late-June visit to WWT Welney Wetland Centre, Norfolk.
First, you have to find and collect the eggs before they're snaffled by predators, which is tricky in the wet grassland habitat favoured by this wading bird. Then you have to transport this extremely delicate cargo safely over the bumpy fenland tracks. Finally, you have to incubate the eggs, mimicking the work of parent birds by turning them multiple times each day, and using hi-tech tools to monitor the health of the growing chicks inside. And the heavy lifting hasn't even begun yet.
"The hatching period is the really intense bit," says William Costa, lead aviculturist at the WWT and a member of the team responsible for the headstarting element of Project Godwit. This five-year partnership between the WWT and the RSPB aimed to boost UK numbers of one of our rarest breeding waders. And Costa has spent countless antisocial hours - 4am is a common hatching time - keeping watch over chicks at this most critical stage.
"Each egg has an ID, linked to its parents in the nest, which we apply to the corresponding hatchling so that we can follow it through its life," he says, showing me around the incubation room in a Portakabin, now mostly tidied away for the season. "If I've got four hatching at the same time, I need to sit and watch them. You just have to be there."

Jump Around - Bagheera Kiplingi - The acrobatic spider with a predilection for veggie food
Spiders eat flies, right? everyone knows that the 45,000 or so spiders in the world are all obligate carnivores, more or less – eating other animals, mainly invertebrates. Nature, however, loves an exception, and one particular spider missed out on that ecological memo. It goes by the wonderful scientific name of Bagheera kiplingi, and its claim to fame is that its diet is – at least mostly – vegetarian.
Female of the Species - Zebras - A strong sisterhood is key to staying safe
Zebras are masters of confusion. Their collective noun is ‘a dazzle’, which is fitting since their bodies and behaviour have been surprising scientists for centuries.
See It, Save It? - Wildlife tourism can be a powerful ally in protecting nature - but it can also harm it. We weigh up the pros and cons.
The sums of wildlife travel aren’t as simple as more tourists equals happier nature. How much did my visit really contribute to the conservation of Lady Liuwa and her habitat – and was that outweighed by carbon emissions from my flights? Did my presence disturb the animals’ natural behaviour more than it reduced the threat of poaching or benefited local communities?The question of whether wildlife travel is, on balance, good for wildlife is a complex one – and there’s no simple answer.
Can Your Really Offset Emissions? - Planning an overseas wildlife-watching trip entails facing some inconvenient truths
Imagine (or maybe you don't need to) that you hanker after the safari trip of a lifetime in sub-Saharan Africa. A 17-day tour beginning at the iconic Victoria Falls, passing through Zimbabwe, Zambia, Malawi and Tanzania, taking in some of the continent’s most wildlife-rich national parks, and ending on the lush island of Zanzibar.
