Seabird Saturday

Our annual gull-ringing trip over to Mullion Island is never the most productive affair, with the Great Black-backs there having very low productivity indeed. But kayaking over this morning we were met with a bit of an eerie silence, with very few alarming adults overhead. It looked like the hot weather had wilted off most of the vegetation on the island, most of which was laying flat, making it hard to check for chicks. But despite our best efforts we could only find a single gull chick on the whole island! We estimated over 60 nests for the island earlier in the year, so if they've only produced one chick then something is very wrong...

Perhaps linked to the poor breeding season of gulls on Mullion Island, there has also been a large gathering of non-breeding Kittiwakes off Lizard Head. We've seen at least on of our Rinsey/Trewavas birds there (but too distant to read the ring), but this morning three French-ringed birds were present, photographed by Terry Thirlaway.

Two of these were birds ringed as chicks in Brittany in 2016 and 2017 (hence definitely not of breeding age yet), but the other refused to show off it's full ring combination so remains a mystery for now.
