The format is the Guardian's Country Diary, one of the longest-running nature columns in English journalism, and this entry does what the best diary entries do: it builds a scene with enough patience that the reader forgets they're being taught something. The setting is Chichester Harbour, between Fowley Island, Thorney Island, and Hayling Island — a tidal saltmarsh ecosystem where grey seals, common seals, sandwich terns, and migrating raptors share overlapping territory. The piece opens on grey seals, and the writing earns its details. Sub-adult seals play-fighting in the shallows are observed with a naturalist's eye — mouthing and nipping, lunging and rolling — and then the diarist quietly drops the interpretive frame: these interactions are social bonding and rehearsal for dominance contests. It's the kind of move that separates nature writing from nature listing. You see the animal, then you see the system. The centrepiece is a confrontation between a migrating osprey and a flock of sandwich terns. The osprey arrives from the north, identified by its long crooked wings bent at the wrist into a distinctive M shape, and drops feetfirst to snatch a fish. The terns — already plunge-diving for bait fish driven to the surface by sea bass — intercept, banking and diving to disrupt the raptor's flight path. When a tern strikes the osprey's back with its bill, the raptor gives up and flaps away. It's a tidy little drama with no villain: the osprey needs to eat on its migration south, the terns are defending their hunting ground. What lifts this above routine wildlife observation is the structural question the diarist lets hang in the air. Ospreys have made a remarkable recovery as a breeding species in Britain — that's the conservation success story. But this individual is just passing through. As the boat returns to the marina, it passes an artificial nest platform installed to attract ospreys to breed locally. The diarist wonders whether this same bird might return in a future spring to establish a breeding territory. It's a small, honest moment of hope that doesn't oversell itself. The prose is controlled and visual without being ornamental. Sentences like 'the autumnal sunlight gilded the sea' walk right up to the line of preciousness and stop. The identification details — Roman-nosed grey seals versus cat-faced common seals, the osprey's M-shaped wing profile — serve the reader rather than decorating the page. This is a writer who watches before they write. The piece is slight by design. It's a diary entry, not a feature, and it does exactly what the form asks: one visit, one observation, one resonant question. The book collection it promotes — Under the Changing Skies: The Best of the Guardian's Country Diary, 2018-2024 — is the natural home for work like this, where individual entries accumulate into something larger than any single walk.
