This year we will be trialling the rear and release of black-tailed godwits in an effort to boost population numbers, using a process known as “headstarting”.
Thirty-two black-tailed godwit eggs have been collected from nests at RSPB Nene Washes – under a licence granted by Natural England. The eggs have been safely transported to specialist facilities at WWT Welney, where they will be incubated until they are ready to hatch. WWT staff will then rear the birds in captivity, until they reach the point of fledging when they will be released to join the black-tailed godwits in the wild at Welney.
Because black-tailed godwits often will lay replacement clutches when nests are lost, we hope that the godwits from which eggs were taken will also go on to lay and rear another brood successfully in the wild. This will give the godwits a temporary boost in productivity, crucial at a time when the UK population of godwits is teetering on the edge at around 60 pairs.
It will be a few weeks until the eggs are ready to hatch and we’ll keep you posted on their progress.
Two tiny geolocator devices were fitted to black-tailed godwits at the Nene Washes today in a bid to find out more about the birds migration movements.
This is the first time that godwits breeding in the UK will have been tracked to their non-breeding grounds. This research will help us to identify key non-breeding sites for the godwits and also provide more information about the timing of the godwit’s migration.
Godwits undertake long and often complex migrations, but they generally return to the same site to breed each year. Black-tailed godwits of the limosa subspecies found breeding in Western Europe spend their winters in Portugal and Western Africa. Over the last two years, we have been marking individual birds from the washes using lightweight colour rings. These have already yielded some interesting sightings from the non-breeding ground, but we hope that we will find out even more by tracking a sample of the birds.
The geolocators – weighing 1g – are attached to colour rings which can then be carefully fitted to the bird’s leg. Geolocators record light levels – these can be used to determine latitude and longitude: essentially providing a location of the individual bird’s whereabouts at a snapshot in time.
We are hoping that we’ll be able to fit more birds with geolocators in the coming weeks. We’ll have to be patient to see the results though – as we won’t be able to retrieve the data until next year when the birds return to the washes to breed.
Project Godwit is a new partnership project between the RSPB and WWT, with the aim of securing the future of breeding black-tailed godwits in the UK. Black-tailed godwits have a small breeding population in the UK, of about 60 pairs, and our new project is aiming to turn around their fortunes. With funding from the EU LIFE Nature programme, we’ll be undertaking a range of activities at the Nene and Ouse Washes including:
An extensive research and monitoring programme of black-tailed godwits at the Nene Washes.
Maintaining and enhancing black-tailed godwit wet grassland habitat at the Nene and Ouse Washes, providing the right conditions for the species to thrive.
A range of steps to reduce the impact of predation on black-tailed godwits, with the aim of increasing nest and chick survival.
Using colour ringing and tracking to improve our understanding of the local and migratory movements of black-tailed godwits.
Trialling a rear-and-release programme, known as “headstarting”, in a bid to supplement the small population of black-tailed godwits breeding at sites adjacent to the Ouse Washes.
Running a range of events for local communities and schools, to raise awareness of black-tailed godwits and their special wetland habitats.
