The remnant river

The weather forecast for this morning had spoken of a “gentle breeze from the north,” with the temperature mooted to feel higher than the actual 14 Celsius. But that wasn’t how it felt at all, walking northwards by the Arun in the face of a cold and gusty wind. And the feeling was confirmed by the fact that no birds were showing in the riverside hedges or reed beds. Proof absolute this was not a breeze, gentle or otherwise.

 Not that the wind would have been an issue for the two species I’d hoped to see. There has been an influx of normally-scarce Cattle Egrets in the last few days, while this is the season when Yellow Wagtails pass through on return migration.

 In the event the cattle in the riverside fields to the east and north of Arundel had attracted neither species to feed on the insects they disturb. Most of the Cattle Egrets are still at sites closer to the sea, while Yellow Wagtails also appear to be hugging the coast. Even there, relatively few of the latter have been reported; sadly unsurprising since their numbers have plummeted over the past few years.

 I’d drawn an equal blank yesterday when walking by the river south from Arundel to Littlehampton. There were cattle here as well, but only in the water meadows at the start of the route, and these also lacked any attendant wagtails or egrets.

 The lack of cattle further south was a reminder that the landscape here is different, the river pursuing an increasingly sinuous course through mostly-drained meadowland as if uncoiling in an attempt to slough off its encasing banks of stone. A pointless attempt because the river that once wandered the plain and millennia ago reached the sea some miles to the east is for now trapped in a built landscape of prison fences and roads, collapsed staithes and concreted banks.

 Still, the abandoned landing stages and stone banks are one of the reasons why this stretch of the river attracts so many Common Sandpipers. There were 18 yesterday, sometimes there are more. At high tide they roost on the stone banks, at low tide feed on the mud exposed below the banks, foraging between the timber and stone remains of the staithes, in a decaying intertidal landscape whose shape resembles the upland streams where they nest.

July 4: Arun South

It’s already hot in spite of the easterly breeze, and the river is sluggish after days without rain. The grass is parched yellow, even the reeds in the ditches wilting. The gull loaf is building up on the stone-lined sections of the river bank and 55 Herring Gulls and 78 Black-headed Gulls have been joined by two Great Black-backed Gulls and single Mediterranean, Common and Lesser Black-backed Gulls. All of them are inactive. Even the Great Black-backs make only occasional forays, scolded when they do so by a pair of vigilant Oystercatchers. A dozen Lapwings dot the muddy stretches of the river’s edge, standing stock still before indulging in seemingly inconsequential runs. Much more active are the seven Common Sandpipers, their numbers up from only three a few days ago, while a single Little Ringed Plover and a calling Greenshank may be harbingers of other less common passage waders in the weeks ahead. There are probably no passage passerines yet. Sedge Warblers and Reed Warbl...

Of rings and records: Med Gulls again

A large number of Mediterranean Gulls are still present at the gull roost on the eastern bank of the River Arun just to the south of Arundel. This updates the previous post. Numbers rose from between one and five birds at the start of the month to 42 on 11 July, peaking the next day at 97 before falling back markedly. The influx appeared to have ended, but numbers jumped again on 17 July. By 18 July there were at least 84 birds by the river and adjacent water meadows at high tide, when birds otherwise spread out along the lower reaches of the river become concentrated at the site. Twelve of the Mediterranean Gulls have carried plastic colour rings on their legs that could be read with a telescope. Few European gulls have received the amount of attention from ringers that Med Gulls have, but even so the occurrence of 12 ringed birds within a week is notable.

Palimpsest

The break in the weather has been spectacular but brief, the sere grass barely acknowledging the hours of wind and rain. But the temporary end of weeks of hot, dry weather has had one lasting effect -- the abrupt disappearance of Mediterranean Gulls from the loaf by the Arun. During the three-week period to late July the rings of 20 colour-banded Mediterranean Gulls were read; the records summarised elsewhere. But now the influx has ended and only one or two of the gulls remain. With return wader passage by the river also weak this year -- the usual Common Sandpipers, Lapwings and Oystercatchers only rarely joined by other shorebirds – another visit to the riverside falls victim to the lure of the high spaces of Arundel Park. Enclosed in the late eighteenth century, the downs forming the 454 hectares of the New or Great Park were moulded into a patchwork of pasture and woodland. Plantations dot the high points of the land, while hangers cling to the flanks of the dry valleys that...
