Fieldwork July 2022

Friday 15 July

Evening recces were carried out at:

Gedney (Nigel) – the marshes were flooded 45 mins before tide with around 100 Curlew over the marsh, around 100 Redshank on the tide edge and 200–300 Black-headed Gulls on the pool.

Beaches (Guy) – Heacham North North, no birds; Heacham South c. 2,000 Oystercatchers; Snettisham beach a few Ringed Plovers and Oystercatchers, but lots of Ringed Plover fencing all along the beach making it unusable for catching. Also noted at Snetts was a Turtle Dove calling and a Spoonbill flyover.

Monitoring Bar-tailed Godwits on The Wash

Bar-tailed Godwits (Limosa lapponica) are large waders which have a wide distribution across several continents. Five subspecies are currently recognised plus a sixth recently proposed as yamalensis (Appleton 2021). Bar-tailed Godwits are long-distance migrants and one subspecies (baueri) makes an incredible non-stop migration from Alaska to New Zealand over the Pacific Ocean lasting many days.

Two populations of Bar-tailed Godwit use The Wash: lapponica breeds from northern Fennoscandia eastwards to western Russia and the Taymyr peninsula and moults on The Wash in autumn, with most birds staying to spend the winter; taymyrensis breeds further east reaching central Siberia and passes through The Wash on migration to its wintering sites, as far south as West Africa.

Fieldwork February 2022

Thursday 17 February

In anticipation of the coming Storm Eunice, Kirsty arrived at the base late afternoon, opened up and replaced the dripping tap glands. Lizzie and Ryan arrived later in the evening after collecting keys from Cathy. Plans were made for recces in the morning, provided it did not look too windy.

Ten years of colour-marking Curlew on the Wash – what have we learnt?

Curlew use the Wash both as a passage site to moult during autumn and as a wintering location. On a global scale, they are ‘Near Threatened’ i.e. vulnerable to extinction and they are present in Internationally important numbers on the Wash. Declines in the UK breeding population have placed Curlew in the highest category of UK bird conservation concern; therefore, the species is a priority for the group in terms of long-term conservation monitoring. We started to mark a proportion of the population on the eastern shore of the Wash with unique leg flags in 2012. This allows us to accurately determine their survival and assess wintering habitat use.

Since then, a total of 478 birds have been marked and we have had over 5,000 re-encounters recorded by over 200 WWRG volunteers and members of the public. We regularly dedicate fieldwork hours to ensure we have sufficient resightings to determine survival and winter distribution. This steady stream of data has started to be used in scientific publications to describe the east Wash Curlew population. This blog is a summary of what we have learnt so far.

Fieldwork September 2020 – Norfolk

Friday 18 September

Lizzie and Ryan arrived on Thursday evening and were kindly let into the house by Cathy, who joined them for dinner and a catch-up. Richard arrived shortly afterwards, and a plan was made for recces the next morning.

On Friday morning, Guy joined the team and recced the Royal Estate, Richard went over to Holbeach, Ryan recced Ken Hill and Lizzie covered Snettisham and Heacham beaches. The morning was crisp and clear with a light onshore breeze. At Holbeach, 19 Greenshank were on the usual pool, 13 Ringed Plover were found on a field at Gedney and 20 Curlew also on a field at Gedney, with more wanting to join, but they were pushed off by dog walkers. A few Curlew were also present on one of the military targets with a large number of gulls.
