We were busy this morning finishing laying a hawthorn hedge near Elaine's seat on the embankment. There we heard a Siskin, Redpoll and a Great Spotted Woodpecker before the rain got heavier.

But before that Harold Heath and Clive Mitchell saw a Kestrel and Sparrowhawk and I found more evidence of Willow Emerald egg galls on some Willow twigs.

Apart from strimming part of the embankment our main focus this morning was to look for the Willow Emerald before the weather changes. They didn't let us down 2 were seen near the hide as they basked and made short flights in the warmth of the sun. 3 Common Darters were also seen (M. White/C. Parkin/CG).

A Bittern thought to have flown from the reserve headed SE over Cudworth's New Cemetery at 08.00hrs. Perhaps towards Edderthorpe Flash (JP).

Around mid-day the temperature peaked at a phenomenal 17c to 18c thereby allowing at least one Willow Emerald to fly for a while. This hardy insect was languishing on a dead Buddlea flower head near the dike a few yards from the bird hide.

Our wildlife group was busy this morning strimming on the embankment. 

After and during working at least 3 Cetti's Warblers sang, 2 Water Rails called a few Siskins and a Redpoll were audible, and a 'Redhead' Goosander seen at dawn left sometime during the morning.

We didn't see any Willow Emeralds, but the sun had gone in by mid-day making it more difficult. However,  a search of some small Willows they had recently frequented revealed some freshly made galls made by the female while impregnating her eggs in to the bark of twigs no more than a quarter of an inch thick (CG/Melvyn White). This is final proof that they are breeding here, after a 3 year search!

A nice surprise for JP this morning when a Fieldfare flew from the little bridge over the dike towards Sunny Bank, it was the first for the autumn, and unusual in that it arrived before the first Redwing.  

c100 B.H. Gulls were on a tilled to the east, 30 Starlings passed over, a Redpoll called and 2 Little Egrets were on the wader scrape (JP/K. Bannister)  

Peter and Annefie Roberts ansd 2 oth members of the Barnsley Narturalists Group visited to look specifically for plant galls. 

Here's what they found; 

On the trees near the Ralph Hibbert’s seat we found quite a lot of Common spangle galls, which are caused by the gall wasp Neuroterus quercusbaccarum (asexual generation). 

These galls were on your photo’s, I believe, little hairy discs with a pimple in the middle. The galls, like most, fall in Autumn from the leaves and stay during the winter in the leaf litter, where the insects continue to mature. The adult gall wasps emerge in the Spring and will then be laying their eggs, in this case on the male catkins, to produce galls of the sexual generation.

Other species we found on Oak around the reserve were: 

Knopper gall, induced by the sexual generation of the gall wasp Andricus quercusramuli.

Silk button spangle galls, caused by the gall wasp Neuroterus numismalis. These galls have been very prolific this year and some of the Oak leaves are completely covered with them underneath. 

A number of Marble galls, caused by the gall wasp Andricus kollari, 

Some Artichoke galls, caused by the gall wasp Andricus foecundatrix,

Some Cola nut galls, caused by the gall wasp Andricus lignicolus, 

A few Pea galls from the asexual generation of the gall wasp Cynips divisa, 

and the tiny egg-shaped galls on the veins of oak leaves of the gall wasp Neuroterus anthracinus (better seen with a magnifier) .

On Alder we found the distinctive pouches near the main veins of Alder leaves, caused by the gall mite Eriophyes inangulis 

On Phragmatites, Lesley found us the Cigar galls, caused by the fly Lipara lucens.

A Little Egret on the wader scrape was the first since 9/8/25! (Karen Pickard/Richard Laverack).

                              Little Egret (John Finch)

Stubble fields to the east produced c60 Linnets, 3 Yellow Buntings, a Red-legged Partridge, a handful of Skylarks and 3 Herring Gulls. Once again demonstrating how important spilled seed on arable land is. Due to the recent drought, the farmer has delayed ploughing/harrowing to plant a new crop because the ground is so hard (JP).

Monday, 13 October 2025

Carlton Marsh

 This morning 6 Teal, 6 Shoveler, Kingfisher, 16 Greylags with Canadas, Cetti's Warbler and Water Rail.

Also a small group of Siskins. 

The Origins of Carlton Marsh (continued)
The disputed meadow we renamed the Western Meadow, had been neglect since 2013, so our wildlife group set about manually chopping down all the Hawthorn, Willow and Birch scrub that had grown. A formidable achievement especially during the Covid Pandemic, when we had to socially distance ourselves from each other to prevent the spread of the vile disease and to comply with government dictate. Since then, we have been helped by BMBC Rangers and YWT to restore the meadow.

In 2023 YWT obtained funding to fence the meadow, so that our Parks Officer, Russ Boland could get a sheep farmer to come and graze it from the latter part of 2024. It is our intention to put cattle on during the summer months, we couldn’t in 2025 because of the severe drought.

In 2023, Dave Smith moved to Amble in Northumberland. Dave was a staunch member of our group. He co-wrote our Annual Natural History Report with me from 1983 to 2024 and spent countless hours birding and ringing here. Needless to say, his input in the data base is much missed.

The reserve has always been managed by a small group of volunteers with help from BMBC Rangers, and for the last 10 years by YWT volunteers.

Down the years we have lost people who have died, notably Robert Laverack, Steve darcy, Frank Hardy, Ernest Jobling, Brian Morton, Phil Wordsworth, Ralph Hibbert, Elaine Evans and Councillor Charles C. Wraith MBE.

Our wildlife group meets every Thursday to do management tasks to keep the site looking at its wild best. Without our dedicated wildlife observers there would be no database. Not forgetting my old friend and founder member, Keith Bannister, who diligently makes sure that the main gate to the car park is opened every morning come rain or shine, and Dave or Claire Richardson, who shut the gate every night.

There have been several officers in charge from the BMBC Parks Department to manage the site over the years, namely Eric Bennett, Geoff Carr, Philip Tierney Kitchener, Nigel Labdon, Brian Hearne, Trevor Mayne and since 2011, Russ Boland. Their role as officers for the Council has been essential for us to gain access to gain grants and Section 106 money, Green Flag and Yorkshire in Bloom Awards and a whole host of other things now help the site gain more status and protection against development to the benefit of wildlife and visitors.
