Birdwatching at Oldbury Power Station

22/5/20 – A Hobby, 7 Swallow and 2 Sand Martin struggling across estuary in strong W wind. AM reported a Lapwing at Pillhead Gout and RL reported a Hummingbird Hawkmoth by the pond next to Lagoon 2.


20/5/20 – A Cuckoo calling from Lagoon 3. (Last heard on 9th.)


18/5/20 – Adult feeding juv. Coal Tit in small wood on mound in SW corner of Lagoon 2. (Looking back at my records they first bred on-site in 2017 and have bred every year since. But they were also regularly seen in 2016 & 2015. In the 11 years before that, back to 2004, I only had 5 records of single birds !) Some video of a bird begging, giving high-pitched calls, but also an adult calling 'teea'.


17/5/20 – The first Moorhen chicks on the lake.


16/5/20 – The Little Grebe was doing its 'trilling' call on the lake and 3 Roe Deer still around. A Whimbrel with 2 Curlew at Shepperdine was only sign of any migration. AM reported 15 Ringed Plover at Shepperdine over HT.


15/5/20 – MP reported the Peregrine low on the nest ledge and a pair of Oystercatcher mating. MS confirmed the Whitethroat eggs (from photo on 9th) have hatched.

      Photos by MS and MP - thanks !


14/5/20 – A pair of Little Grebe on the lake, with a Mute Swan. 30 Stock Dove feeding on newly ploughed (and probably seeded) field by yacht club. And a pair of Canada Goose with 8 gosling on the estuary.


13/5/20 – A Red Kite flew low (virtually over my head !) to NE along the shore at Shepperdine at 1pm. And a female-type Marsh Harrier reported by BD, rose up from Lagoon 3 and flew inland. (And also reported on 11th.) Very quiet over the High Tide on the estuary, just: 1 Mute Swan (upriver), 7 Black-headed Gull and 1 Oystercatcher (the only wader).
(NB. Another Red Kite was reported along the road between Thornbury and OPS 'in last 2 weeks'.)

      LP has emailed to say she found these Water Rail feathers on what looked like a raptor kill along the bridleway to the shore ! (Most probably a Peregrine night-time kill on a very late migrant, on 11th.)

22/3/20 – Some vismig this cold and sunny morning: 100+ Meadow Pipit to NE (inc. flock of 74 through low at 9:10am), 3 Collared Dove flew along shore past Lagoon 3, 2 Stock Dove and 50+ Woodpigeon. Unfortunatley, I flushed the Peregrine pair from their Woodpigeon meal on the seawall by the waterworks. Looks like they had eaten most of it. And a Mute Swan in the middle of the estuary.


21/3/20 – DW reported: a summer plumaged 'Scandinavian' Rock Pipit by Lagoon 3 outflow, 20+ Sand Martin and 30+ Chiffchaff.
This morning, a male Wheatear still by Oldbury Pill sluice, 20+ Chiffchaff (15+ singing), a pair of Tufted Duck on the Lagoon 1 flood (!) and 3 Peregrine over the towers - the adult pair and an immature; the female adult was very vocal, but the pair showed little aggression to the young one. I guess it was last year's young, as a bit early for this year's.


20/3/20 – Late afternoon, a Swallow with c25 Sand Martin feeding over the flooded Lagoon 1. (Swallow 4 days later than the earliest ever at OPS from last year.)
MP reported this afternoon, from Oldbury Pill: 10 Wheatear together, 83 Curlew, 1 Sand Martin and a singing Corn Bunting.
AM reported this morning: 42 Sand Martin (flooded Lagoon 1, in flocks of 15, 20 and 7), 33 Chiffchaff (inc. 15+ in the bushes on Lagooon 1), a Blackcap singing along the Bridleway, 45 Woodpigeon (groups heading NE into wind) and 45 Wigeon.

      Swallow and Sand Martin

16/3/20 – LP reported a Black Redstart on the waterworks fence and a Comma butterfly. Glorious sunshine this afternooon. The Corn Bunting was sat on a bush at the yacht club common. A Siskin over to North, and a near record OPS count of 17 Buzzard (record is 18). 2 Goshawk circling with 6 of the Buzzards on far side of estuary (i.e. Gloucs.). 9 Chiffchaff singing around the site, a Jay singing and doing amazing mimicry of : Buzzard, Magpie and Rook calls, and a pair of Gadwall at Shepperdine. And the 3 Roe Deer that have been around for some time are so used to me that they just sat as I went past, just 30 yards from them !


15/3/20 – 7 Stonechat together on shore towards yacht club.


14/3/20 – The first signs of vismig this morning: c35 Woodpigeon descended from very high when a shower hit and landed in trees, a Sparrowhawk headed north across the estuary, 2 Meadow Pipit and a Skylark over.
The boat below is the only one that has ever attempted to go upriver between the Tidal Reservoir wall and the green 'Ledges' buoy ! It grounded on the rocks, but was lucky the tide was still coming in and refloated.


13/3/20 – 2 Coal Tit together in Lagoon 2 pines, a pair of Green Woodpecker on Lagoon 3, a Little Grebe on the lake and 3 Water Rail still calling.
AM also reported: 4 Chiffchaff (3 singing), 17 Teal, 34 Wigeon, 65 Turnstone and 21 Wren.

      Mute Swans on the flooded Lagoon 1 and Colt's-foot flowering on Lagoon 3.


11/3/20 – A probable Goshawk flushed c100 Woodpigeon from fields/hedges to SE of Shepperdine, and flew up the valley towards OPS, but intermittent (telescope) view through trees, distant and with heat-haze. Two pairs of Stonechat again by the jetty, and one of the males was SINGING - a first for me at OPS ! And 1+ Little Grebe still on the lake, trilling.

      'Headstarted' Curlew no. '23' from Slimbridge at Shepperdine again (ring last read here in Dec 2019).


10/3/20 – AM's WeBS count: 1 Little Grebe, 2 Tufted Duck, 2 Canada Goose, 29 Mallard, 2 Shelduck, 105 Wigeon, 48 Teal, 66 Turnstone, c100 Dunlin, 7 Snipe, c90 Redshank, c100 Curlew, 1 Grey Plover and 2 Peregrine (on the towers).

Also c460 Common Gull; c110 downriver out of overnight roost and a flock of c350 flying up from fields inland.

      4 canoes from the Wye Valley washed up on the shore - all damaged except this one I dragged above tideline. They belong to a company at Symmonds Yat. (I've contacted them, and hopefullly they can recover them.)

18/2/20 – c55 Redwing today.
The river above the sluice at the yacht club burst its banks (well, it spilled over onto the Common) at the weekend. Looking at the River Level information, it had its highest recorded level on Sunday night, beating the record that went way back to 26th Oct 2019 !


17/2/20 – c25 Linnet, 22+ Chaffinch and a Mistle Thrush feeding in the very wet maize-stubble field along the main rhine. And still 2 Blackcap (male + female) in the Anchor Inn car park.

MP has uploaded a video of the Starling murmuration over Lagoon 3 from January.

      A Skylark on the yacht club common - strangely, it was eating a small slug. And a very large branch of a Willow tree has come down, by the newly thrashed hedge along the main rhine.


      The lake is as full as I've ever seen it.


14/2/20 – The Peregrine pair reported courting on Avonbirds..


13/2/20 – Some excellent birds, despite the wintery showers this morning. A Short-eared Owl flew along the bridleway to the shore and turned left along the shore towards Lagoon 3 at 8am. Then at 9:30am an adult male Marsh Harrier went slowly downriver past the yacht club and along the shore towards Littleton. But then at 10:20am it was quartering the reedbed on Lagoon 3, giving superb views until 11am when I left. (Video of it over Lagoon 3.) It flushed c25 Snipe from the reeds, and another 10+ seen along tideline. I also found a Corn Bunting along the tideline at High Tide, by the yacht club. It then perched in the hedge there. (Video of it preening.) It was with c25 Meadow Pipit, 1 Rock Pipit and 2 Skylark.



9/2/20 – 6+ hours spent watching the estuary today (4 in morning, 2+ in eve), but no seabirds blown in by Storm Ciara.

30/1/20 – The female Black Redstart in the waterworks again. It favours the 'Seal Pit' by Lagoon 2, but I am only finding it when it is vocal - calling 'whit' repeatedly. (Today because a sewage lorry was up other end, and last time due to a perched Crow.) And 4 Stonechat still (2 x Lagoon 3, 2 x near jetty).


29/1/20 – A Goshawk 'scoped over ridge on far side of estuary (i.e. Gloucs.). An adult with gleaming white underparts and light grey above. Very distant, but perfect viewing conditions - bright sun from behind me and zero haze. It was soaring and doing some exaggerated slow-flapping display flight, for about 3 mins.. (Recalled SE Owl when slow-flapping.) 4 Buzzard and a pair of Peregrine seen along same ridge in same half hour for size comparison.


27/1/20 – A Short-eared Owl getting hassle from corvids, and went to roost in middle of Lagoon 3 at 3pm. And a Chiffchaff again at south end of Lagoon 2.

A note from JS on the Curlews: "At the last WeBS count there were 315 at Aylburton Warth and 80 at Guscar Rocks. I reckon there are no more than 650 on the river, down from about 1000 ten years ago."
