The two whitefronts were resting near the ditch.
Toby's mention of the right of way had us checking the PCC website - sure enough, this appears to show the old route through the farm buildings (running diagonally through a shed!). This was the subject of a temporary, much later permanent diversion by PCNP, 30-40 years ago, when the sheds were constructed athwart the path. Why this map should be on the website today - no idea, it's wrong. The present route leaves the road above (south of) the church, and crosses the Corse to the east of the former route. Maps of both below - the new official route highlighted in yellow (as per the official PCNP map - approx location of the geese today indicated by blue circle).

Luckily I met Will the farmer as I got back to my car, and asked him about it. He confirmed that the "yellow" route is indeed the route, not the one through the yard, and he is very keen that people do not go down to the yard, or indeed turn left after the sewage works, without permission, as it isn't a PROW and you might meet a dairy bull (Rob Lewis and I had a narrow escape a few years ago) - this is the normal WEBS route, but strictly with the farmer's permission. Mike Hayes turned up at this point, and was able to hear all this again. With Will's permission I was able show Mike where the geese were today.
A further source of confusion: on the new route you may encounter an overgrown stile, no longer maintained. If you do, retrace your steps a short way as the route now runs along the other side of the hedge.
