Project Godwit in 2017

As the year draws to a close I thought I’d take the opportunity to reflect on the last twelve months of Project Godwit, and pick out a few of my own personal highlights. As we look forward to 2018, we know we have more to do to bring godwits back from the brink – but we’ll be working hard to give them a fighting chance.

In 2017 we have…

  • Released 26 juvenile godwits into the wild at WWT Welney. You can relive the moment the fledglings were released via the video here. Headstarting has enabled us to boost productivity (the number of chicks produced per pair) to one of the highest levels in recent years.

  • Fitted tiny geolocators (tracking devices) to sixteen black-tailed godwits. When we see these birds again in spring, if we can catch them, we’ll be able to download the data and find out where they’ve been spending the winter.
  • Made the Nene Washes and Ouse Washes even better for black-tailed godwits – by creating wet features and pools. We’ve already seen many birds enjoying the new scrapes and we hope the godwits like it when they return in spring. We also installed a new pump at the March Farmers section of the Nene Washes which will enable us to manage even more habitat for godwits in the breeding season.

  • Installed over 3500m of electric fencing at the Nene Washes to help protect nests from predators. We saw a significant increase in nest survival in fenced areas, but we need to fence more areas of black-tailed godwit habitat in 2018.
  • Received a resighting of a female breeding bird (YR – RL(E)) from the Nene Washes from Senegal. What’s remarkable is that she has been spotted in Senegal for the third winter in a row. You can read more about her here.
  • Introduced over 130 people to the black-tailed godwits through special guided tours at WWT Welney. Keep your eyes peeled for 2018 dates.
  • Became part of the Back from the Brink Programme. Back from the Brink is one of the most ambitious conservation projects ever undertaken. Through 19 projects delivered across England, 20 UK species facing extinction will be brought Back from the Brink thanks to a £4.6 million grant from the National Lottery. Natural England, the government’s wildlife advisory body, will work in partnership with Amphibian and Reptile Trust, Bat Conservation Trust, Buglife, Bumblebee Conservation Trust, Butterfly Conservation, Plantlife and the RSPB. https://naturebftb.co.uk/

I’d like to also take this opportunity to wish you a Merry Christmas on behalf of the team – and to thank the team for their incredible work throughout the year. I’d also like to extend this thanks to the birdwatching community who have been keeping an eye out for the godwits. Thank you very much for your support.

Results from the wild in 2017

Increasing productivity in the wild is a key focus of Project Godwit – so how did the wild godwits fare in 2017?

Challenges at the Nene Washes

The Nene Washes hold 80-90% of the UK breeding black-tailed godwit population. We found 35 breeding pairs on site in 2017, a decline from 42 pairs in 2016. Our monitoring tells us that there is a strong relationship between breeding success and population change – it will not come as a surprise to most that better breeding success leads to a boost in the population in subsequent years. We know that breeding success has been low for this population over the last couple of years, which probably explains the decline observed in the population this year. Black-tailed godwits are long-lived birds, and most don’t return to breed until they are two years old, so there can be a time-lag before a population change occurs.

Black-tailed godwit pairs need to successfully fledge one chick every other year in order for the population to sustain itself, or half a chick per pair each year. In the last three years, the number of chicks fledging at the Nene Washes has been below this level, which is a cause for concern. A big focus of Project Godwit will be to boost the breeding success of godwits at the Nene Washes, and increase the number chicks that successfully fledge.

Trials and tribulations

In recent years the main driver of poor breeding success at the Nene Washes has been predation, and our research has shown us that different predators have had varying impacts in different years. It’s a complex picture, and one which will require a range of predator management solutions resolve. We are monitoring black-tailed godwit nests at the Nene Washes (under a special licence from Natural England). Our monitoring tells us how many nests have hatched and (in most cases) the cause of failure when they don’t. We are also radio-tagging a sample of chicks once they have left the nest. Our approach to predator management is based on the evidence we gather from this extensive research and monitoring programme.

One solution we are trialling is the exclusion of ground predators from key breeding areas using temporary electric fencing. Exclusion fencing has been shown to boost wader productivity at other wet grassland sites but this is the first time this has been tried at the Nene Washes. In 2017 we found that there was a significant boost to nest survival for waders which nested within the boundary of the fencing. However, unfortunately we had a number of godwits nesting outside of the fencing this year, and those nests did not fare so well. We’ll be upping the ante in 2018 – providing exclusion fencing over a larger area. Five chicks fledged successfully at the Nene Washes in 2017, we hope this figure will increase in future years of the project.

More good news from Welney!

The good news is that the three pairs present at Welney in 2017 successfully fledged two young in 2017. This small population has been very productive in recent years, which bodes very well for the headstarted birds which will hopefully return there to breed in future years. We have released 26 birds through the headstarting programme in 2017. This has provided a huge boost to the number of young godwits in the population this year. If we can match this success with improved wild breeding success at the Nene Washes, alongside the continued successes at WWT Welney, then we should be looking at a much brighter future for our black-tailed godwits.

Will Tiny Tracking Devices Reveal Godwit Migration Secrets?

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 Gets Underway

Welcome to our new website!

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.
