Juvenile Oystercatcher on beach

Oystercatchers and shellfish

Posted on by

Back in the winter of 1992/93 Wash Group members noticed far more Oystercatchers than usual were feeding inland – on grass verges, in the middle of roundabouts and on the lawn at Sandringham. The Oystercatchers we caught had stopped moulting part way through, presumably to preserve energy and we found many hundreds of corpses on the shore. This led to an investigation of what had happened and, of course, the answer was complicated – but WWRG data helped to unravel the mystery. The Oystercatchers had encountered a ‘perfect storm’ of unusually cold weather combined with low stocks of both Mussels and Cockles – the preferred food of many of them – and a popular human food as well. Work with BTO, Eastern Inshore Fisheries & Conservation Authority (EIFCA, then the Eastern Sea Fisheries Joint Committee), the Centre for Environment, Fisheries and Aquaculture Science (Cefas) and Richard Stillman at the Centre for Ecology and Hydrology (CEH), showed the importance of balancing numbers of shellfish taken by the fishermen and the birds to ensure that there were sufficient for both as well as maintaining a breeding stock of shellfish, so that the supply continues. Understanding these balances, what might change them and how to react to changes (Adaptive Harvest Management) is a vital part of managing fisheries.

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.

Friday 5 November

Most team members started to assemble at the base house from mid-afternoon (breaking the peace of Bernard and Carole who had been staying for a few days already). A mini-Glastonbury was then established outside to accommodate the large weekend team. Cathy, along with Lynne and Alex, provided a hearty meal of jacket potatoes with all the trimmings for the bulk of the team, followed by a fruit salad (Lynne), and a chocolate hazelnut tray bake (Alex) which was big enough to last the entire weekend (thanks to Tim and Ian B for washing up!). Katharine, Sophie, Alice, Rob, Sam and Skye all arrived later, with Rob blaming his later than planned arrival on the necessity to bake a carrot cake for the team, starting at 17:15…

The following trip report was written by Sebastian Cooksey, age 14

BOOM! The cannons fired and the best weekend of my life had just started. After lying for around an hour in the grass, we suddenly rushed to our feet and were running to the catch. From first glance, we realised it was a wet catch, nonetheless we waded into the water and started the process of ushering the birds up onto the drier beach. Water flooded into my wellies, but the excitement overpowered the discomfort. When the birds were all up on the beach, nicely rolled into a pocket, we could calm down. I could appreciate what we had caught, lots of pearl-white Sanderlings mixed in with a few Ringed Plovers. We could now start the extracting process and I was going to just stand and watch the experienced ringers have the fun, but Rob encouraged me to go do some extracting and before long I had three Sanderlings in my hand ready to put in keeping boxes. I was really grateful that Rob encouraged me to get involved and I feel like all the other people I met on this trip were all just as welcoming and trusting. This is what made me enjoy this weekend so much.

Plan for the weekend

This was always going to be a challenging weekend! We had a number of targets and hoped to achieve some of them. The weather forecast was for it to be mild, with light winds, but foggy nights and early mornings.

We had arranged for BBC AutumnWatch to come out and film our work but they could only make the Saturday morning. We had still failed to catch a single Curlew on our east shore study area and had ten GPS/GSM tags to deploy. This is the single largest expenditure on a project that the group had made (£12,000) in its 60-year history so we did not want to have to leave them in a box until next year. We then had an Oystercatcher tag that had already been on two Oystercatchers and had just been found on a beach after the silicone harness had broken (as they are meant to do).
