Fieldwork November 2022

Recces:

Lucy Y. and Mark went out to recce in the morning. Around 07:00 at the Heacham Dam, Snettisham North, Lucy saw no birds, but by 07:15, groups of 30–200 Sanderling began to gather; Lucy also looked at Heacham South where 1,500–2,000 Oystercatchers were already present at 07:00, and stayed until 10:00, settled even with dog walkers going past the flocks on the beach. There were also a few hundred Oystercatchers roosting on the concrete slope of the Heacham Dam. Mark saw 10 Sanderling and six Turnstone at Heacham North, and 10 Oystercatchers at Heacham North North.

Avian Influenza (AI) precautions: With the spread of AI to wild birds (mainly colony nesters), we followed BTO guidelines and also introduced extra safety precautions to minimise risk – see here. There were also some sites we did not have access to for catching.

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.

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.
