Endangered birds will receive £230,000 of “home improvements” including security cameras at a nature reserve.
A "bespoke habitat" for curlews and lapwings will include anti-predator fencing and new pools and at Gallows Bridge Farm, Buckinghamshire.
Berkshire, Buckinghamshire & Oxfordshire Wildlife Trust is carrying out the work with a grant from the FCC Communities Foundation.
It said curlew numbers have "plummeted" over the last century, with its conservation status now "red".
Mark Vallance, the trust's land manager, said: “The curlew is one of our most bizarre and beautiful birds; it has this iconic, downward-curved beak, and it makes a famous 'cur-lee' cry.”
The trust said curlews had been nesting at Gallows Bridge Farm for years, but “their numbers are limited by predators”.
Officers will cut back hedgerows to reduce the opportunities for birds of prey to attack the curlews, which the trust said would also benefit one of Britain’s rarest butterflies, the brown hairstreak.
The trust will create “enclosed nesting areas” surrounded by anti-predator fences that will keep out foxes and badgers, to protect other threatened species such as the lapwing and redshank.
The trust, along with volunteers from the Upper Thames Waders Group, they will use night-vision cameras during nesting season to analyse what threats the birds are facing and how well they are breeding.
Curlews and other wildfowl such as wigeon and golden plover will be able to bathe and feed in 30 new pools called scrapes.
The trust said the project would also benefit other ground-nesting birds such as skylarks, meadow pipits and yellow wagtails.
Penny Horne, spokesperson for the FCC Communities Foundation which gets funding from landfill operators, said: "We’re excited about the plans the trust has in place to improve the nature reserve for wildlife and visitors alike.
"We’re looking forward to this project making a difference to the endangered curlew population very soon."
