Another new species for Linacre!

 I've had a couple of 2-hour visits to Linacre this week and managed to record lots of insects, including a new species!

The first walk, on 28th, with 3 of the volunteer rangers, resulted in the new species, a queen Median Wasp, that was seen, basking on the bracken next to the middle reservoir.

Other insects seen on this walk were: Common Blue Damselfly, Common Dater (1 - the first of the year), Brown Hawker (1), Migrant Hawker (1), Peacock (1), Gatekeeper (6), Green-veined White (3), Speckled Wood (1), Large White (2), Small Copper (2), Ringlet (1), Comma (1), Meadow Brown (a minimum of 10), Common Blue Butterfly (2 males, in the field beyond the top reservoir).

The second walk, yesterday, didn't bring any new species, but it did give several interesting sightings, including a female Wall Brown, an egg-laying female Common Blue Butterfly (in the ringing site), a minimum of 10 Red Admirals and lots of 7-spot Ladybirds. Other sightings were: another Common Darter (down by the ringing site), 1 Migrant Hawker, 1 Brown Hawker, 9 Green-veined White, 1 Large White, 4 Meadow Browns, 4 Commas, 3 Speckled Woods and 1 Holly Blue.

Two species of hoverfly were also recorded: Volucella pellucens (2nd record of the year) and Volucella inanis (1st record of 2025).

Rufford Gulls - 29th July 2025

 I spent two hours at Rufford yesterday afternoon. There were about 65 Black-headed Gulls present, including 17 juveniles, and 4 darvic-ringed birds.

The darviced birds were 258A (first ringed in February 2020 and reported 42 times, mainly in Rufford. Today's sighting was the first since March 2025), 207C, 258C (both first seen back on 15th July) and 234F (ringed on 9th November 2024, as a 1st winter bird, seen 8 times last winter and last seen in February 2025).

Big Moor Dragons - 26th July 2025

Yesterday, Jayne and I had a walk up to Little Barbrook Reservoir on Big Moor. We went to look for dragonflies, and managed to see a couple of new species for the year.

The highlight, as always, was our first Golden-ringed Dragonflies of 2025. We saw two individuals, both males, including this one that had, unfortunately, damaged its body, presumably whilst emerging. Despite this, it appeared to be doing ok, and we got very lucky, when it perched by the main path eating a wasp!

Other odanata seen were: Emerald Damselfly (new for year), Black Darter (1) and Common Blue Damselfly (2 males).

A few butterflies were on the wing: Gatekeeper (8), Small Heath (1) and Red Admiral (1).

Birdwise, it was very quiet, but we did manage to see a couple of Reed Buntings, Meadow Pipits, a Common Buzzard, and a single, juvenile Stonechat.

Ring-necked Duck - again!!

Ring-necked Duck isn't a species I see that often, especially not in Derbyshire, so a report of an eclipse male at Ogston Reservoir this week had my "twitching" instincts up and running. As it turns out, this is my 3rd record this year, and my second in my home county!.

I popped down on Thursday morning (24th) and found the bird within 2 minutes, right out, on the water, in front of the public hide. The light was awful, but I got great 'scope views and managed a few half-decent photos.

Year List Update - 20th July 2025

As always, at this time of the year, the Year List slows down, as most of the easier-to-find species have been recorded. I have, however, managed to add a few new species.

The first is Long-eared Owl (179), that was seen in NE Derbyshire in June. Next up was Crossbill (180), that was recorded at Linacre on 5th July. Spotted Flycatcher (181) was seen on a walk in Tideswell Dale, also on 5th July. Green Woodpecker (182) was heard, but not seen, at Hardwick Hall last week, and the final bird, Yellow-legged Gull (183), was seen today, at Ogston Reservoir.

Update: Common Sandpiper (184) was seen at Ogston, on 28th July.

Back to Rufford

 An hour at Rufford on Tuesday (15th) produced 5 ringed Black-headed Gulls, including a new metal-ringed bird from Sweden. Overall gull numbers were up markedly on my first visit, with 94 birds seen, including the first juveniles (6).

The Swedish-ringed gull, 6434047, an adult, was found in the usual spot, by the pontoon. This bird was ringed, as a pullus, 12 years and 2 weeks ago, 1697km away!

The other ringed gulls were all well known to me, having been ringed at Center Parcs over the last few winters. They were 273A (ringed on 17th November 2021, as a 1st winter bird, making it 4 years old), 293A (ringed on 15th December 2021, as an adult, so at least 6 years old), 207C (ringed on 22nd December 2022, as an adult, so at least 5 years old) and 258C (ringed on 1st December 2023, as a 1st winter bird, so just 2 years old). Good to see them all in their breeding plumage.

Linacre Insects - 13th July 2025

A couple of 6-spot Burnet moths were also seen in the field by the top reservoir (second record for Linacre) and a single Cinnabar Moth caterpillar was also spotted.
