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.

Colour marking schemes and WWRG

Posted on by

Regular attendees to The Wash (and everyone we encounter) may wonder why we typically devote one out of three tides of fieldwork to resighting colour-marked birds (as well as having some ‘resighting only’ weekends). Using colour marks alongside metal rings allows us to study aspects of wader ecology which cannot be investigated using metal rings alone. We now colour mark a variety of species and further information on our colour-marking schemes can be found here.

Fieldwork October 2022

Posted on by

Tim, Selena and Dave arrived at the Norfolk base earlier in the week to work on house and garden maintenance. In particular they removed a large amount of the excess vegetation that had grown up in the garden and Dave in particular helped wire up the potential decoy store. Cathy joined them for some of the time and Mark also helped out but wasn’t able to stay on for the weekend. This team put in a significant amount of effort over these few days and so deserve a big thank you from the group!

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.

Feeding Bar-tailed Godwits on the Wash, by Cathy Ryden

Monitoring Bar-tailed Godwits on The Wash

Posted on by

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.
