A very hot day on Hilbre and not much bird movement apart from a Swift that flew over mid-morning. Attention turned to invertebrates with 8 species of butterfly being recorded. Large Whites were the commonest but small numbers of Small Tortoisehell, Red Admiral, Gatekeeper, Meadow Brown, Green-veined White and Common Blue were recorded.
A single Large Skipper was also seen but didn’t stay still long enough for a photo! Lots of Six-spot Burnet moths were nectaring on thistle and Birdsfoot Trefoil.
Ringing activity focused on trying to catch and colour ring Rock Pipits as part of our long term project. Two new birds were added to the register with CBV being one of this year’s juveniles. CBX was ringed as a juvenile in July 2020 and subsequently recaptured a month later but there had been no further encounters.
A real surprise was a very juvenile Wheatear caught & ringed.
Harebells are flowering in the Obs garden and Common Centaury can be found in small patches around the island.
A highlight of this time of year the building up of Sandwich Terns and there are now around 750 adults and juveniles on the sand banks on the east side.
