Cathy braved some pretty awful weather to recce on Friday morning. There was a nice flock of around 400 Oystercatcher roosting on the dam itself, whilst Heacham South was unusually quiet for people, dogs and birds. There were small numbers of birds at Heacham North, with around 50 Oystercatcher, Grey Plover, Turnstone, Ringed Plover, Sanderling and Knot, all well distributed along the beach and not suitable for catching unfortunately.

Tim arrived to help with the afternoon recce, and along with his arrival came some nicer weather. Both Cathy and Tim were on site well before tide, finding the beach at Snettisham virtually empty; most Bar-tailed Godwit were still offshore and headed straight to the pits as the tide came in, with Oystercatcher doing a similar thing. At the dam, there were around 300 Oystercatcher loafing on the Mussel scar just offshore. As the tide came in, there were well over 1,000 Oystercatcher gathered on the mud around the dam and further north at Heacham, most of which eventually gathered on the Mussel scar. Eventually, around 200 birds came ashore south of the Tump, whilst the rest of the birds gathered on the scar were scared off by dogs and headed south to Snettisham.

Mark was on hand to kick the weekend off as he headed to Heacham and Snettisham to recce for possible cannon-net catches for the Saturday morning. The Tump was quiet with no Oystercatcher present, and further along towards Heacham there were Sanderling, Turnstone and a few Oystercatcher scattered along the beaches, but nothing providing a suitable catching option. Thus, it was decided that Saturday morning would be a resighting morning.

Later that evening, 13 team members gathered at base house and enjoyed Cathy’s now famous baked potatoes, Eton mess and good company.

Cathy did the recce on Friday morning, arriving at the dam by 07:50 and found no birds on Snettisham beach. There were three flocks of Oystercatchers on Heacham Beach with 21 Curlew at the northern end of the flocks. The Curlew were flushed by the first dog walker and flew inland. As each Oystercatcher flock was approached, the birds flew south, joining the southernmost flock. In total there were about 110 Oystercatchers on the tide line.

Toby visited Heacham North at 10:08 as the tide uncovered the mussel scar and watched a mixed flock of 40 waders, the majority being Oystercatchers with only one or two Knot. One of our Oystercatchers A3K and a couple of our Turnstones were resighted during the morning.

If you have taken part in WWRG winter fieldwork over the past twelve years, you know that one tide of each fieldwork weekend is dedicated to resighting colour-marked birds. We have been applying leg flags to Bar-tailed Godwit since 2010, and Curlew since 2012, with over 200 people reporting one or more flag sightings. We use individual leg flags to both add to the survival data generated from metal rings (see Cook et al. 2021) and to look at how individual birds use the Wash and the surrounding area. Our first paper analysing how birds move around within the Wash has just been published in the journal Wader Study (Pell et al. 2023).

Report on recce at Heacham Dam by Hilary & Cathy

We arrived at Heacham Dam at 13:10, when it was sunny with a rather gusty stiff breeze. A pre-roost flock of 350 Oystercatcher had formed just south of Heacham Dam. They were on mud close to the tideline and mixed with <10 each of Curlew, Knot, Ringed Plover, Grey Plover, Sanderling and Turnstone.

Small flocks of Oystercatcher flew in from the north, but larger flocks flew off to the south as the tide approached. At 13:50 the tide reached the edge of the sand/shingle but by then all the birds had flown south, despite there being no disturbance by humans or dogs. At 14:10 we noticed a flock of 25 Oystercatcher on the sand/shingle c. 100 m north of Heacham Dam. These were quickly disturbed by dog walkers and flew off south. It was concluded that there was no realistic catching opportunity.
