This could be the very definition of a “record shot”! 😂 Black-headed Gull 295R has arrived back at Yeadon Tarn, Leeds, after an excursion to Schleswig-Holstein, Germany 🇩🇪 #GullOfTheDay #GullsOfYeadon #Chroicocephalus #ridibundus #NWBHGs

Black-headed Gull 20JJ is still at Yeadon Tarn, Leeds. It was ringed as a pullus on 13 June 2026 in Flixton, SUFFOLK and arrived in Yeadon on 13 August. #GullsOfYeadon #GullOfTheDay #Chroicocephalus #ridibundus

Shibden Park, Halifax, today. I get the impression that the migration of European gulls to the UK hasn’t really started yet. 225K is a regular here and has never been seen anywhere else! Coot RX6 is showing its age now.

This Tachinid fly is one of two that emerged from a Comma pupa. They had obviously parasitised the caterpillar before it pupated. #VC64 #Diptera #Parasitoid

A tiny ichneumon has emerged from this long-lived Luffia lapidella larval case. I suspect the parasitoid might be a female Diadegma naryciae but I will have to get my old microscope out to look for confirmatory features. #Larva aeterna #Campopleginae #Ichneumonidae #VC64

The Norfolk-ringed Black-headed Gull (2A1Y) is still at Yeadon Tarn. Ringed as a nestling on 27 June at Marlingford Hall, it appeared at Yeadon two weeks ago at the same time as a bird ringed in Suffolk. I wonder how many others are from East Anglia? #Chroicocephalus #ridibundus #GullsOfYeadon

I have just watched a Speckled Wood lay these two eggs on the underside of a blade of the Cock’s-foot grass that I allow to grow on our old coal bunker. I have found the caterpillars here in previous years and assume that the sunny, west-facing, sheltered location is suitable 😀 #Parage #VC64

Our garden vixen has a bright white tail-tip despite the rest of her coat being quite melanistic. There are several theories as to why the white tip can be useful. She continues her habit of peeing in the water bowl!

A strange thing happened. I found my first ever yellow colour-ringed BHG at Yeadon Tarn on Wednesday and discovered that it originated from Norfolk. Yesterday I went back to get a better photo and found another one! 20JJ was ringed as a pullus on 13 June 2026 in Flixton, SUFFOLK #GullsOfYeadon

The metal ring on this Black-headed Gull, at Yeadon Tarn, tells us that it is 5 years old (born on Dallow Moor, Nidderdale, in 2021). This bird also came to Yeadon last Autumn. It doesn’t seem to travel far. I wonder if it has ever even seen the sea! #GullsOfYeadon #Chroicocephalus #ridibundus

Wacky and very unexpected addition to the Portland ringing tally - a juvenile Yellow-legged Gull lured in with stale bread rolls from last weekend's Obs AGM and caught in our giant drop-door trap (constructed years ago in a futile attempt to catch Ravens but now repurposed for gull catching)

BHG 2N42 among a flock of 21 birds at Guiseley McDonalds today. Ringed as a juvenile at Bowness in Dec 2018, it has spent every winter there since. Probably now on the way back to Windermere from its breeding ground. #GullOfTheDay #GullsOfGuiseley #Chroicocephalus #ridibundus #NWBHGs #Windermere

It is uncomfortably hot for Homo sapiens but butterflies seem to be thriving! Small Tortoiseshells, Gatekeepers and second generation Holly Blues have appeared this week. I am pretty sure that a Comma laid eggs high up on the garden Hop yesterday so larvae should appear soon. 😀 #VC64

After two weeks of complete inactivity the Luffia lapidella case has started twitching and has possibly even moved position. Something is alive inside the case. Hoping for a healthy moth but it could be battling with a parasitoid.

A rather scruffy Painted Lady butterfly in Baildon today. A more pristine one was also seen on the same bramble patch but disappeared before I could get a photo. My first Hummingbird Hawkmoth of 2026 was nectaring on the flowers of a Lime Tree in a Guiseley car park yesterday. #VC64

Lesser Black-backed Gulls at Redcar Tarn, Keighley, today. The younger bird has been colour-ringed by the North-West Gulls Group so likely originates from the Bowland Fells.
