Today I managed to get to the top of Traprain Law, which is an ancient, weathered volcanic plug, rising abruptly from the plains of East Lothian. It's not actually all that high but for me it might as well have been Mt Everest, and is the first 'blob' I've been up for six years, because of my wonky heart - so I'm feeling smug
There is a large ancient fort on the top and the whole thing is run by someone like SNH. There is a herd of a dozen or so Exmoor ponies grazing there, but otherwise the vegetation is left in a natural state, mostly open grassland with herbs and wildflowers.
The whole place was positively heaving with skylarks, singing high above us, then plunging back down to their nests
It was glorious. We did notice that their song was not exactly the same as the skylarks over our land, so maybe there are regional variations or accents.
This got me to thinking, is the concentration of skylarks here so high because Traprain Law is an isolated oasis in a desert of grain crops, or were there this many skylarks per similar area all over the country in pre-mechanised days?
(Modified to say: Oops, just remembered it's not a volcanic plug but a laccolith. I think the difference is that a plug forms when a volcano has erupted, then what's left in the vent solidifies there. I think a laccolith forms when the lava didn't quite reach the surface so forms a dome. Not a whole lot of difference from the point of view of the skylarks, but someone here is bound to notice
