Birders excitedly pointing

It's a great sight, when you roll up at a place to try to see some birds, and a bunch of birders are there excitedly pointing at something. I rolled up at Bockhill early this morning, intending a stroll along the cliffs, and a gaggle of the Bockhill birders were indeed excitedly pointing at a clump of grass.
Jack had added yet another great find to his long list, and eventually a Fan-tailed Warbler/ Zitting Cisticola (don't ask) showed itself before flying high and far away.
Imagine for a moment that the bird above is a Zitting Cisticola (it isn't - it's a Meadow Pipit, but an illustration of some kind is called for). The Bockhillers probably got excellent photos, as the bird was more obliging before I got there, but I've no complaints.
A walk along the cliffs to Langdon Hole failed to find the Zitter (unsurprisingly) or indeed a Ring Ouzel that had been seen there (ditto), but three female Black Redstarts showed, and I was able to check on the nesting Kittiwakes. I reckon that there were about 50 birds at the Langdon end and 60 nearer St Margarets, with a small colony of about 15 nests in between. This is probably up on the last couple of years, albeit way down on a decade or so.
There are, however, plenty of predators in the wings........
