Thompson Water, Norfolk

Poor visibility greeted me upon my arrival at Thompson Water.  Low cloud, mist descending into thick fog, and a dawn temperature of 4 degrees Celsius.
As with any season, and any conditions, Thompson Water still had beauty, and a mysterious feel to it, the sounds of calling Ducks reassuring you that life goes on, albeit out of sight in the fog.
I was rewarded upon my arrival by the beautiful whistling calls of Wigeon, the 'kleeps' of Teal, the slapping of Mute Swans wings upon the surface of the water, and the occasional burst of song from a nearby Cetti's Warbler.

A male Cetti's Warbler was seen reasonably well and close to within thick reed cover.  As is typical with this species, this particular bird rarely ventured from cover.  Although seen quite well, I never had prolonged views of the bird, the poor light allowed mostly darkened views of the bird as it moved between thick clumps of reed, often entering the habitat and being temporarily lost to view, and then being picked up again as it moved between cover in fast, direct flight.  The Cetti's Warbler usually kept low within cover, being close to the surface of the water.  On one occasion the bird appeared to pick something from the waters' surface, or possibly took a drink.
This Cetti's Warbler was a typically rounded looking bird with a wide, square-ended tail.  The upperparts were dark (brownish) and the underparts appeared whitish, however, the light was so poor that good detail was not seen.  The bird often gave bursts of its explosive song as it moved around.  This was one of two singing Cetti's Warblers at Thompson Water this morning.

Having left Thompson Water, |I was walking back towards the village of Thompson when I heard many Pink-footed Geese flying over, but were unseen due to the fog.  I have previously encountered this species over Watton during poor visibility.
