Interested in birds, butterflies, moths and plants. Helping to monitor the movements of migrating Black-headed Gulls 😀
Merseyside Ringing Group’s Black 2440, the 1cy Black-headed Gull from Shotton Steel Works, Flintshire is still at Yeadon Tarn, Leeds, where it has resided for more than a month.
Hopefully it will stay here for the winter.

The parasitised Luffia lapidella larva hasn’t moved for three days and has fixed itself to the side of the Perspex container.
It will be interesting to see what emerges!

I've been updating our collaborative #CootStudy database. I started the study 17 years ago & thanks to a network of bird ringers across Britain & Ireland we've now colour-marked 4,400 Coot & received over 13,000 re-sightings. Pretty cool for a bird you hardly see in flight! #Ornithology #BirdRinging

The parasitised Luffia lapidella larva, which should have metamorphosed in the summer has made it to Halloween.🎃
It stopped feeding last week and wandered away from the lichen substrate provided for it.

This Larva Aeterna seems to be the last of the Baildon Luffia colony 😕

Welcome amelioration in the weather allowed for fuller ringing activities at the Bill today. 43 birds trapped; 17 of the new birds were Redpolls and the one control was another Redpoll that had first been ringed at Thorpe Marsh, South Yorkshire, on 26th September - nice!

There were no summer sightings this year but in 2024 it visited Nordjylland, Denmark, so it is probably safe to assume that it has been there again.

Down but not out! The parasitised Luffia lapidella larva is not dead after all. After five days of inactivity it has “done a Lazarus” and resumed feeding on lichen.
This is a great example of a larva aeterna and it might be some time before the culprit reveals itself.

The parasitised Luffia lapidella larva hasn’t moved since Friday 10th October.
Presumably the moth caterpillar has now been killed by the parasitoid larva and we now have to wait until the culprit emerges as an adult wasp.

Peter Coffey (Merseyside Ringing Group) says 2440 is unusual for its direction of travel (NE). The only other Shotton-born BHG moving in a NE direction was one to Ashworth Moor, Rochdale.
Most go to Ireland, mainly east coast and Tralee/Killarney 🇮🇪 but occasionally France (Brittany, Finistere). 🇫🇷

Speckled Wood caterpillars often appear in the wild grasses that I allow to grow in a sheltered west-facing position on top of our old coal bunker. It looks a bit messy but the butterflies seem to like it!
The grass is mostly cock’s-foot I think 🤔

It was probably ringed by the Merseyside Ringing Group and further details will hopefully follow.
Maybe blown in this direction by Storm Amy? 🤔
