No recces due to time of tide relative to
daylight. Phil arrived mid-day and walked along Snettisham
and Heacham beaches hoping to find droppings and other evidence
of the presence of flocks as had been evident on the visit
a fortnight earlier. Since nothing found marked four net sets
near where the birds had actually roosted on the failed attempt
on that occasion.
At the Terrington base, equipment was organised
for setting and by prior arrangement, Nigel stopped at the
fish and chip shop to collect food for the team so far assembled.
A rendezvous time of 20:30 had been arranged with team members
going straight to Snettisham so arrived somewhat before that
and waited by the gate. The local constabulary were the first
to arrive! Having convinced them of our credentials took the
four wheel drive vehicles through the flooded track to the
beach and set the four nets.
Briefing at base and bed before midnight.

Saturday 4th
Up 05:45. Cars had to be defrosted and at Snettisham there
was a very light snow covering. Phil and Leigh crept into
the hide and soon established there was a flock of Oystercatchers
(ca. 400) on the beach near the nets. As light improved it
was felt the majority of these were the hide side of the nets
but difficult to be sure due to the distance involved and
position of hide. Also a flock of 100 Grey Plover and Dunlin
fairly close to the hide.
Graham as long-stop and then Nigel as roving observer confirmed
that there was a maximum of 40 Oystercatchers catchable. With
the tide already falling off this was unlikely to improve
unless twinkling was attempted. Hence Phil abandoned the hide
to twinkle. Initial movement disturbed the birds in the area
and reduced the catch to 20. A very careful crawl twinkle
was then done and succeeded in moving the birds along the
beach. On the final push a large proportion of the flock got
up and whilst some went south to the Snettisham Reserve the
rest landed in the area of the nets. It was obvious that to
try to push a higher proportion of the flock in front of the
nets would have been a high risk operation so with a catch
estimated to be three figures two nets were fired. In the
event only one net caught birds but the catch was

The high proportion of adult birds in the
flock with at least eight of the retraps being ringed in the
second half of the 1970's was very satisfactory. Just one
birds was a juvenile.
As the tide went out the falling tide site
was observed but few birds queued up on the beach before the
mussel bed became exposed. Other recce information was provided
by Jeff and Allison who had found 50 mixed waders (15 Grey
Plover, 15 Sanderling, and Purple Sandpiper, Knot, Turnstone)
on Heacham Far North. No waders were on Heacham South.
Meanwhile Jen had been observing the
Turnstone at Port Sutton Bridge and there were 120 present
with 40 colour-ringed birds (22 of which were from the catch
2 weeks ago and the remainder birds ringed in previous years).
An advantage of Jen being at Terrington was that the team
could phone as they left the beach and order breakfast!

The journey back to base was interrupted
for most people with a stop at the side of a harvested sugar
beet field to look at a flock of 4500 Pink-footed Geese. With
no good (or even half decent) wader option for cannon netting
on Sunday morning the possibility of making a goose catch
was considered. Contact with the WWT confirmed this could
be valuable but in the end the logistics and size and state
of the field ruled it out.
Departed shortly after 14:00 to set mist
nets on the Terrington marsh, despite a rather stronger wind
than anticipated. A line of 5 set directly out from the barn
and the usual 9 nets set in an 'E' shape out from the next
causeway east. Returned to Terrington base for food before
putting out tape lures at 18:00. Still quite breezy and cold.
A few birds had been extracted when
the lures were put out but the next round had both teams finding
their nets full of birds. With the tide slightly higher than
predicted, the water just reached the pools. All birds had
been extracted by 20:00 and the nets were immediately taken
down. Processing done in the white barn as usual with the
generator providing decent light.

Sunday 5th
With no catching attempt the opportunity
was taken to look at some areas which, for various reasons,
are not normally visited by the group. Hence had a lie in
until 6:45 and got to the sites by high tide.
| Old Hunstanton / Holme (PI/CC/BM) |
Offshore from the Holme
golf course there are two high tide shingle islands forming,
stretching towards Old Hunstanton. No spectacular numbers
were seen and the flocks were fragmented but the totals
were in the order of; 500 Oystercatcher, 400 Knot, 300
Bar tailed godwit, 150 Dunlin, 100 Grey Plover and a few
Sanderling and Turnstone. Nearly 100 Snow Bunting on two
flocks on the mainland beach was nice to see |
| Snettisham North (TT) |
250 Oystercatchers where
caught on Saturday! |
| Sailing Club Bay (TT/KS) |
Roosting on the beach, 1500
Oystercatcher and 1500 Knot. Also at an hour after high
tide as mud became exposed, 200 Sanderling, 100 Dunlin,
150 Turnstone, 50 Redshank, 30 Ringed Plover and then
joined by large numbers of Bar tailed Godwit. The RSPB
warden confirmed there were no Black tailed Godwit about. |
| Snettisham Pits (SD/LW/LN/AK) |
6-7000 Oystercatchers and
a flock of c12,000 knot roosting on the shingle bank.
Only other wader seen on the pits was a solitary Turnstone.
|
| Outer Bund (NC/RR) |
On the side that could be
observed from the mainland, no Oystercatchers present. |
Team reassembled for breakfast and then sorted
out equipment prior to an early departure. The pink footed
geese were still happily feeding on their field, to within
40 metres of the road and houses!
