Great White Egrets

 I stood in a hide, at the RSPB's splended Ham Wall nature reserve in Somerset, in view of Glastonbury Tor, that small tower sat atop a hill overlooking the Somerset Levels, the marshes of Avalon, alleged stamping ground of King Arthur and his Knights, where Pagan Britons and Christian Anglo-Saxons apocryphally made play for the heart and soul of what we now call England. A mighty bird stood in front of me, just metres away, filling the 75-250mm lens of my camera, all in white, bill turning from black to yellow, fishing, preening with an air of magisterial indifference. The bird stood tall, the shape of a skinny Grey Heron, or an albino woodpigeon with a snake threaded through it, wearing stilts. It stepped forward, creeping, and stared at the water, with the suggestion of intent, before continuing to preen itself.  When noisier people entered the hide, it flew away, low across the water to a new position behind the reeds.




This experience would have been unheard of a few decades ago. First recorded in Britain in the mid 19th Century, though possibly with a history here going back much further, the Great White Egret was a scarce vagrant, less than annual until the 1990s, then annual wintering, I saw my first in 2010, at Dungeness in Kent, where a wintering bird, earning the universal Great White Egret nickname of 'Sharky,' had taken up home in a far flung reedbed. It was little more than a speck in my scope, the size of the bird, its height against the reeds, and its bright yellow bill (which turns black in the breeding season) making it unmistakeable. Great White Egrets are sometimes considered confusable with Little Egrets, but in reality I find them more confusable with a swan, on account of their huge scale in comparison with the more familiar of our two white herons. If you think you might have seen a Great White Egret, you haven't. You have seen a Little Egret. If you see a Great White Egret, you know what you have seen.




My next encounter with the species was in Greece, where I worked as a volunteer for the Hellenic Ornithological Society. A flock of 30 'Sharkies' had dropped into the brackish water marsh, cleared out from their breeding grounds, looking for somewhere to spend the winter. I watched in wonder as they stood stock still in the mirror still water, harbingers of a changing season. Southern and Eastern Europe once held the nearest surviving Great White Egrets. Once common in much of Central Europe, Great White Egrets, like so many charismatic wetland species, were victims of persecution as competitors for fish, and of the millinery trade in the 19th and early 20th century, pushing the centre of their European population East, with birds shot off their nests in the breeding season for their showy breeding plumes, a bold fashion statement for a Victorian lady to wear on her hat. The species has a wide distribution spanning five continents, and many North American colonies of Great Whites faced similar persecution. It was seeing the fate of these birds on their nests which spurred into action the ladies who went on to found both  the RSPB and the Audobon Society, whose campaigns eventually saw the species have something of a repreive, on both sides of the Atlantic.  So it was from Southern and Eastern Europe that the species began to spread.




In 2012, the species bred in the UK for the first time, on the Somerset Levels, at Shapwick Heath, a stones' throw from my Great White Egret experience. In 2017 it bred in Norfolk. Its breeding population continues to grow, and all these breeding attempts have involved small colonies of multiple pairs, on stick nests in trees, not dissimilar to Herons and Little Egrets. In January this year, one flew over my house in Wirksworth, Derbyshire, easily distinguished from a little egret by the sharp bend in its neck, protruding like a keel, and by its vast size and yellow bill like a sword. I have seen them standing in the fields by the Derwent of a morning with the Grey Herons, presumably joining them in munching any small mammals driven from cover by the intense winter cold. Several pairs breed at Shapwick Heath, and it was the most numerous Heron I saw at Ham Wall, and they winter up and down the country, including at Attenborough in Nottinghamshire, where their flights to roost are a popular sideshow to the spectacular winter Starling murmurations.




The Great White Egret is doing well. And I wholeheartedly approve.  Within minutes of its departure, no sooner than the hide was quiet again, my Great White Egret was back, ducks herding their broods away into the reeds with justified concern, and back to preening, nonchalantly, at home in this place of Arthurian legend.
