Before the weekend

When planning the fieldwork dates for 2003, the Saturday morning tide had been discounted as too low and early to be considered for catching or useful recces so the plan was for the team to assemble Saturday afternoon rather than the normal Friday evening. This turned out to be a very good move since Thursday evening saw the South East corner of Britain covered in snow and resulting traffic chaos. Travelling on Friday was not recommended but with conditions improving and no more significant snow forecast it was decided to go ahead as planned.

Saturday 1st

The team assembled at the Terrington base from early afternoon, with snow still lying on the ground and a temperature around freezing but little wind. Lots of comment about the relative merits of the new base with central heating in comparison to the old West Newton base! Equipment sorted and ready to set by 15:00. With a good team, plans were to set in two places on the saltmarsh at Terrington (E). A quick look over the sea wall to determine exactly where to set revealed a large lump had appeared on the mudflat edge directly out from the barn. Inspection through binoculars revealed this to be a sperm whale!

The two lines of nets were set and the team setting nearest the whale, joined by Phil and Sarah who had initially stayed behind to sort equipment, walked out to inspect it. This walk revealed a surprising amount of ice and snow on the saltmarsh for a short lived cold snap and that the previous tide had come nowhere near the pools the nets were set on. The whale was about 15m long and too high to see over. No one stayed down wind of it for long!

After a brief break back at base, tape lures were put out and base camp set up out side the barn since this was now occupied by a heard of young cattle. With tide relatively close to sunset, it was not until just before high tide that a net round was made and everyone went out on to the saltmarsh. The eastern line of nets caught just five birds although this lack of birds was probably due to the tape in the tape lure breaking. The other line found about half the rest of the catch in the nets initially. A sweep out to the tide edge and back found a sizeable flock of dunlin on another pool (considered earlier for a possible net) and this pushed more birds into the nets that had been set.

Having dealt with these, cannon nets needed setting for the morning, relative tide heights having prevented this being done earlier. Phil and Nigel left the rest of the team to clear the Terrington (E) area and, having picked up the cannon net setting trailer, went to a fish and chip shop in King's Lynn to order food for the team. Here the rest of the team arrived just as the fish and chips were being served up.

On Snettisham, with no recce information, the plan was to set by the wooden stake where the main concentration of birds had been the previous month. Whilst marking where to set it was reassuring to find droppings from what had obviously been a substantial flock. Four nets set reasonably efficiently but it was still well after midnight when all had returned to base. Despite a 05:15 get up time, sat around with tea, coffee and / or Port for a brief period before bed.

 

Sunday 2nd

Up 05:15. Frost overnight after thaw during the day made roads slippery. Arrived at Snettisham and in place about 06:45. The hide had been set at the northern end of the set, on top of the seawall just south of the new concrete section and this meant that Nigel and Adam who manned it could crawl in without showing themselves to the beach. Base soon had a report of an 'oil slick' - the flock of Oystercatchers - on the beach in front of the nets with some concern that the tide was low compared to the nets. As it became lighter and the nets were positively identified this was confirmed but there were birds catchable. The flock was approximately 3000 birds; spread in front of all four nets and a hundred yards either side of them. There were no birds within 6 yards of the nets and none of the eight yard markers were visible. However as it became lighter the two maximum extent markers (at either end of the net line) became visible, about one yard into the surf. Nigel was concerned that the force 4 wind along the beach might mean that a lot would beat the net out especially as the nets were set with only 2.5 metre jump ropes. With tide now at its maximum and the net not going to go into the sea far, two nets were fired on the south end of the line where the flock was densest. During the small amount of lifting to get the edge of the net out of the water quite a lot of birds escaped but nevertheless, the catch was

With a cold breeze on shore, keeping cages were set behind the sea wall. This is the first catch over 500 by the Group since 1996! Encouragingly, after food shortage problems the Oystercatchers had in the Wash some years ago, the birds were in very good condition with satisfactory winter weights. Of the 84 birds with rings, there was a good spread of ages with the oldest being first ringed in 1976. Although there were no foreign ringed birds, one of those caught wearing a WWRG ring, put on in 1980, had been previously recorded breeding in the Faeroes in 1988.

Catch dealt with by just after 11:00. Back to base for breakfast and to sort out the equipment. Departure mid-afternoon by which time a lot of the snow had gone and wind strength was increasing.
