Country diary: The mayhem and mystery of inland gulls | Derek Niemann

May brings frequent, vocal, and striking gull activity far from the ocean. Grey-tinted bodies, dark underwings, and black-backed plumage appear as different age groups and non-breeders move through the landscape. Birds drift westward up the hill in loose flocks, sometimes play-fighting and then being pulled back into formation. Overhead, large aggregations crisscross soundlessly like aerial country dancing, while close pairs fly together and emit piteous cries. Down the valley, herring gulls compete for the dawn chorus and practice territoriality, including noisy disputes over ridge tiles and church spires, with one bird calling out to local landmarks and harbors.

"May is the month when they are most ubiquitous, most vocal, most beguiling. Up the combe they come, riding over the rising sun as I sit here to write and look out at the big sky. One glides before me, underwings dark, bib and belly uplit to cast an ethereal glow. A paint chart might well label this grey-tinted body hue gull white. Two bigger birds appear, slender wings slanting as they turn to flash a glimpse of upper, the thundercloud blueblack of black-backed gulls."

Then one would be distracted, luring the whole group sideways before reluctant obligation pulled them back on course."

"There is generally a morning westward drift up the hill. I don't know where they go. And what, I wonder, is the purpose behind the great agglomerations that gather overhead at any time of day to crisscross each other as if performing aerial country dancing? This is usually a soundless spectacle, unlike the pairs that fly close, uttering piteous little cries, prompting my wife to exclaim: Sing up, gulls!"

"Last week, they staged an unholy row over ascendancy on the ridge tiles and twin spires of Trinity church. One perched in temporary dominance, threw its head back and belted out its eulogy to fishing boat harbours, rockpool adventure and sand-filled sandals. No matter how much w"
