Sunday starts with an S and so do most of the birds seen today!
Ringing this morning with Luca and Lucile went really well. Our mission was to catch an unringed wild brood House Sparrow. A brood we have been seeing since the third week of June and during each ringing session, one of its siblings have been caught and colour ringed, blood sampled and pit tagged leaving just the one bird out of three. This for context was the only unringed House Sparrow of ringable size on the island. Yes, the Sparrow Project has reached that moment where they have almost completed what most Pokemon players dream of. Alas today was the day, Lucile ringed a brood in a box and whilst checking the traps I returned with our target individual. Almost completely the same biometrics as the previous two, we knew we had finally found our last fledged wild brood - until the next! Starlings in comparison were caught and we processed 14 in total - 1 new and 13 retraps. The retrpaping is great, watching their mould develop and the birds being a lot bigger now then they were in the nest back in May! A cute round circle and soon to have that glossy plamage for the first time.
A couple of Sand Martins heading south later and at 10am I gave a walk and talk about Manx Shearwaters, showing guests and staff our cutest and fluffiest breeding birds we have on the island currently. These birds are growing well and it was a surpirse to have another new chick born. A bird we thought was a failure, succeeded. Having an expected hatch date of the 22nd June, it is certainly a 'late one' though not too late in the Shearwater world. It is so great watching them grow and to be in the company of people who love the Shearwaters too! We really feel priveliged every time. On our way back, a seemingly slight passage of Swifts was ongoing with some coming a few metres in front of the face! More came through later which was nice.
Gathering a team together after some lunch we checked on our Swallow broods. With fine weather and adults happily feeding, we manged to ring two broods whilst another brood were too small and the final one on eggs. This means we have had at least 6 broods of Swallows this year, a high in recent times!
Back to the office for admin and catching up on emails before an evening of blog and log later!

This morning Greg headed out to monitor the Guillemot plot and arrived to a slight surprise. The ledges that have been so chock full of birds were almost entirely empty. Now, this is the time of change in the seabird world as the chicks have been fattened up with Sand Eels over the last couple of weeks and are ready to make the treacherous jump down into the sea and begin their final development into an adult out on the open ocean, accompanied by their father. Therefore, the sight of just one single chick left on the plot should have been no surprise, but it was still a shock to have such a visual reminder that the season is coming to an end. Now it is time for Autumn migration to begin!

Over on the East, Jessie was counting the Fulmars at Gannet’s Rock where they saw the first couple of downy chicks appearing on the ledges. They were also accompanied by a young Peregrine Falcon getting a good look at both Jessie and the Fulmars. Today was a good day for spotting Peregrines across the island as many adults were out with their fledged young with the distinctive calls heard from the office in the village. Eleanor spotted a group of four over at the Quarry later in the evening.

Another raptor sighting was from Thomas, who spotted a possible Hobby chasing the Swallows and Swifts over Barton Field. Unfortunately, there was quite a glare off the sea to get a definite ID; thinking initially that it was a Peregrine, he then noted that it was quite small and was being mobbed by the Hirundines – a common sight when Hobbies are around. However, it may have been a young Peregrine trying its luck with the Swallows.
As the Auks are rapidly disappearing from the cliffs, we decided to head to Jenny’s Cove this evening to see if we could glimpse any jumplings in action. It was a beautiful clear evening with the cove bathed in the golden light of the setting sun. Puffins were looking extra beautiful scattered down the grassy slopes and suddenly more visible on the large rocky face where they are often hidden among the Guillemots. A usually cacophonous section of coast, the cliffs were strangely quiet tonight. Instead of the constant gargling noises of the adults, the loudest calls came from chicks, a distinctive high pitched squeak that in some cases echoed all the way up from fledged chicks in the water down below. We managed to spot one Razorbill chick with its father, that had already made most of its way down to the rocks near the base of the cliff, when they both jumped into the water and swam off together into the sunset. A couple of Great Black-Backed Gulls were also on the prowl, the remaining chicks extra vulnerable without the safety of a full colony.

My morning began with a short walk over to the castle to join a sea watch organised by some volunteers from the mainland! The Sea Watch organisation has a large network of volunteers who regularly survey for cetaceans from land, and these two volunteers in particular visit Lundy every year to run a series of watches. Unfortunately, there were no cetaceans around this morning for us to record. We did, however, spot 4 Gannets, a Peregrine Falcon and a Kestrel.

After some lunch and admin in the tavern, Chloe and I headed to the landing bay for a BRUV Deployment. We dropped the BRUV on the north side of rat island, right on the edge of a rocky reef with lots of kelp. During this hour long deployment, we recorded 5 fish species, three cnidarian species and a lobster! I was able to identify some seaweed species in the footage: Mermaids Tresses, Forest Kelp and Wireweed.

The data we collect from the recreational fishing area in the landing bay will eventually be compared to data collected in the landing bay. From this we should be able to determine whether the no take zone is higher in species richness than the fished zones around the island. Today we recorded two Corkwing Wrasse, one of which was an adult male. There is a good chance that these two corkwings could have a nest in the rocks near our deployment site. We also had 2 Ballan Wrasse, 6 Juvinile Pollack, 2 Sea Bass and 13 Two-Spotted Gobies.

Once we had retrieved the BRUV, I enjoyed a little free diving, during which I spotted a large Candy-Striped Flatworm, the two sea bass we caught on camera earlier, and many more jellyfish - including a beautiful Blue Jelly which I managed to swim into. Luckily their stings are only as painful as nettles. I ventured back down to the landing bay much later that evening, with some other brave swimmers on the island. We hoped to swim with the Bioluminescent Phytoplankton in the water after sundown. It was a perfect night for it, as the moon was waning and rising very late. The bioluminescence was visible from the surface of the water in the shallows, but swimming off the jetty was truly magical. We all sparkled beneath the water, it felt like swimming through the night sky! The columns of the jetty also glowed, as barnacles feasted on the shining plankton. After a lot of excited squealing and splashing, we all headed up the hill to bed, dodging the Manx Shearwaters as they came in to land near the road.
The best photo I could get of the bioluminescent algae in the waves. Doesn't really do it justice, but proof that it was there!
