Rye Harbour Nature Reserve Wildlife Sightings: August 2025

August saw the fourth official heatwave of the summer of 2025, which has been confirmed as the hottest on record for the UK by the Met Office.

This is the month when autumn bird migration really kicks in. The numbers of birds present on the reserve ebbs and flows throughout the month as weather and other factors shape passage.

Wheatears were seen throughout the month, with Flat Beach and the main path down to the sea being the best places to look. There were at least 12 seen on the 2nd. Generally just single Whinchat and Spotted Flycatcher were seen at several spots around the nature reserve. We only heard of one Common Redstart, in the scrub at the south end of Castle Water on the 28th.

Sometimes a common bird seen at an unusual location can cause excitement, so a Treecreeper in the trees by Harbour Farm on the 3rd was of note.

Castle Water is always a good place to look for migrating waders. Maximum numbers of selected species during August were four Green Sandpiper, four Common Sandpiper, one Wood Sandpiper, one Curlew Sandpiper, two Ruff and three Black-tailed Godwit.

Other interesting sightings at Castle Water included juvenile Cuckoo on the 10th and the 21st, Little Owl on the 12th, Dartford Warbler on the 18th and an impressive count of nine Great White Egret on the 19th.

Flat Beach proved the best place for scarce waders this month with two Little Stint on the 11th, a Curlew Sandpiper on the 12th and five juvenile Wood Sandpiper on the 13th, when there were also 110 Dunlin and 80 Ringed Plover. Five Greenshank on the 24th was the best count of the month for this popular, graceful wader.

A Black-necked Grebe was at Ternery Pool on the 1st and four Snipe were back at Barn Pool West on the 2nd.

Autumn Garganey can be easily overlooked without their breeding plumage. Look for a small duck with a striped head pattern and a pale blob at the base of the bill. One was seen on Barn Pool West on the 12th and another at Ternery Pool on the last day of the month.

We can look forward to more spectacular autumn sightings of Osprey as the UK breeding population continues to grow. One was seen over the Discovery Centre on the 2nd and another on the 25th . There were several sightings of a single Hobby and the first Merlin of the autumn was recorded on the 28th. There were several counts of over 500 Sandwich Terns at Flat Beach during the month. A few late Swifts were feeding over Nook Meadows on the 30th.

Several Bee-wolf wasps were seen near the Marsh Mallow 'forest' at Castle Water early in the month. The enormous Large Conehead bush cricket, Ruspolia nitidula, has taken a foothold on the nature reserve in the last couple of years and was seen at a new location near Harbour Road, Castle Water on the 12th. Small Coppers were in flight nearby towards the end of the month.

Plants in flower during August included Least Lettuce, Dwarf Mallow, Strawberry Clover and a few Autumn Lady's-tresses at Castle Water.

The moth trap continued to attract large numbers, including a Swallow Prominent, Rosy Wave, Frosted Orange, Large Thorn and a Starwort. There were also two occasions when a Great Silver Water Beetle was an unexpected discovery.

    Loved all the photos – and had been unfamiiiar wth the juvenile cuckoo and the conehead bush
    cricket. There were more excellent wildlife and beachscape photos up at the annual Camera Club exhibition at St. Mary’s Centre, Lion Street last Saturday.
