Many of the birds released on June 20 were not expected to hatch due to the terrible condition of the eggs as a result of the late spring downpours.However, the eggs, which were rescued from muddy farmland, and the chicks were safely raised until old enough to look after themselves. This practice is one element of Project Godwit a partnership between the Wildfowl and Wetland Trust (WWT) and the RSPB - which aims to restore the UK breeding population by collecting eggs for rear and release, known as head-starting. WWTs Nicola Hiscock oversaw the hand-rearing process. She said: Even though we began head-starting godwits in 2017, it didnt make the release any less nerve-wracking. We had a real issue with flooding this year which meant some of these birds literally started life buried in the ground. So to watch them take their first flight was very, very special. Over the next few weeks well check on them daily to make sure theyre ok. But then, theyll be off on migration and we probably wont see them again until they return in the next year or two. The fledged godwits are expected to join up with the wild fledged birds and spend time in the Fens before migrating to southern Europe and Africa for the winter. The conservation group said that eight of last years released birds had returned to the county after travelling south of the continent. Black-tailed godwits will often return to where they were raised to breed, usually within the first two years. Hannah Ward, RSPB project manager at Project Godwit, said: It was a big day for the team and the UK black-tailed godwit population. With less than 50 pairs of godwits breeding in the UK, its crucial that Project Godwit boosts the number of young birds entering the population each year. The Fens has the largest number of black-tailed godwit nests in the UK, but in recent years they have really struggled to hatch and raise their chicks in safety. We are using a number of techniques to try and help the birds breed successfully in the wild. The Nene and Ouse Washes in the Fens are the two main breeding sites for black-tailed godwits in the UK. Conservationists have been using a technique known as head-starting - raising young birds from eggs collected in the wild - to help boost the UK godwit population. Their numbers at the Ouse Washes are now critically low but its hoped that head-starting in combination with the creation of wetland habitat could restore the population to the numbers previously seen in the 1970s. Head-starting is just one aspect of Project Godwit which also focuses on monitoring, habitat management and trialling conservation techniques. Project Godwit is a partnership between RSPB and WWT with major funding from the EU LIFE Nature Programme, HSBCs 150th Anniversary Fund, Natural England and the Heritage Lottery Fund, through the Back from the Brink programme and Leica UK. The project aims to secure the future of breeding black-tailed godwits in the UK. Conservationists are encouraging birders to look out for these special birds.
