FWIW keps, living in London no surprises, any Dipper encounters would only ever be made in the hill country of the North West, with numerous visits over the years them being occasionally seen (quite a novelty for a London Lad) darting up river only to be lost in the shaded reaches of a snake bend, or bobbing up and down on a stepping stone before plunging into silvered stream, without ever consciously thinking about calls or song!
Fast forward the decades until a few years back (a cold November day), I was found propping up the bridge parapet in Ludlow Shropshire, idly staring into the almost deafening roar of the river, when I heard a vibrant virtuoso burst, so liquid clear and unexpected that I was temporarily “immobilised”. The bird was singing beneath the bridge arch upon which I was slumped, clearly the acoustics were so superb, I could not compute what I was hearing!
Sounding like (to my ear)...a cross between Reed Warbler and Nightingale, I was totally bemused that such a rich almost equatorial sound could be heard under grey leaden skies in middle England on such a day. When all was “revealed” as it arrowed from neath the arch, I was somewhat staggered that a bird which wasn’t even on my “minds ear” radar should deliver par excellence. :t:
