My day started at 4am this morning, a slight glow in the sky and the sounds of the Millcombe Song Thrush, plus a rather active Swallow filled the air as I disturbed from my sleep. The original (non-bird) alarm was set a little later and I was up, washing up by 5am so everything was ready for the morning. I then headed down to Millcombe in the first really nice sunshine we have had for a while. It was also quite warm to start and by 6am I had the nets open.
Millcombe woke up. The session was quite quiet to begin, though a Spotted Flycatcher flying around the Gas Store was a highlight. There were 10 birds caught, ringed and/or processed today: 3 new Linnets, including a stunning adult male; our breeding pair of Blackcap with the female being new and the male caught earlier in the Spring; a new juvenile Chaffinch fully fledged and ready to go; a retrap breeding Goldfinch and a retrap breeding Dunnock. The highlight for me are always the lesser know and lesser appreciated birds so the new juvenile and retrap adult Wren were pretty good highlights. Even more so, we found it’s nest! A rather artistic looking one and one we will record for the BTO Nest Recording Scheme in due course.
I packed up around 10am, as it got a little too warm to be sat in the blaring sun. I came back to the office, completed some of the Bird Day admin, inputted the ringing data, and before I knew it, it was lunch time already.
The Conservation Team met up in Barton’s Field with the aim to catch the presumed moulting Mallards, however little to our knowledge but the ducks had not started moulting and flew off as soon as we got there. The ducklings were no where to be seen and the temperature rose more so we all headed off a little hot but alright. The butterflies and moths out today were nice to see, a walk around Millcombe in the afternoon yeiled two broods of fledged Willow Warblers, with another brood reported to have fledged at the Terraces too! On dropping off the ringing book, I took it a little steadier ahead of my Tavern shift covering for a poorly member of staff.
Eleanor and I worked together, had dinner together and decided a summer solstice walk was needed. We walked through Millcombe and found 3 Pipistrelle Bats and heard the first jumping Guillemot chick, a sign of things to come and a weirdly seasonal change as we head into midsummer/ ornithological post-breeding/autumn!

Today started on the middle of a cliff, under the sole light of two red head lamps and a light drizzle. It was around midnight. Gaya was recording Manx shearwater responses to different conspecific vocalizations, with an interval of 30min between each playback to reduce disturbance. The two birds she targeted produced no response, and we wondered if we had spent two hours recording empty nests under a sky that threatened to show us what British rain is like. This is part of science ! The silence of the Manxs was soon broken by a good amount of them enjoying the bad weather conditions to come back on the Island, and we probably saw 30 of them flying around in the last 20 minutes on site. It reminded me of the first night I joined the team of ringers to catch Manx on this cliff, one of the most beautiful of my life. The sky was full of birds and stars that night. Walking on the cliffs was intimidating at first, but the presence of all group-members and learning more about Manx aging and sexing from Thomas made it a most wonderful memory.

A very rainy day today, but luckily it was still quite warm on the island. Most of my planned activities for the day revolved around the water anyway, so I didn’t mind getting very soggy. The assistant warden team aimed to test our baited remote underwater video (BRUV) setup today. This is the camera trap that Chloë mentioned in her last blog post.

We hope that this will be a very useful tool in assessing which sea creatures are thriving within lundy’s marine protected area, as we can use this camera to count how many different species are present in a given area. Chloë, Tara and I spent a good part of the day attaching the camera, bait canister and weights to our frame. We had a couple of setbacks, including a broken camera, a lost camera and some issues with mounting the camera that we did have. Once we’d fixed these issues, we lowered our BRUV onto the seabed to film for an hour, and went to do some rockpooling!

We were supposed to lead a rockpool ramble today, but the weather did not allow for that, so the three of us went for a ramble by ourselves! I was very happy to find two sea slugs (my favourite animals) in the pools, Favorinus branchialis and Antiopella cristata- the crystal sea slug!

This was my first time finding a crystal sea slug myself, so I was very excited. Favorinus is also an exciting find, as this species of slug feeds on the eggs of other nudibranchs, so its presence here shows that there are lots of slugs around.

We also found an interesting fish, a large edible crab and both types of cushion star! The most commonly reported cushion starfish (Asterina gIbbosa) and has many different colour morphs, whilst the other type of cushion starfish (Asterina phylatica) is a lot smaller, and can be identified by the red star in the middle. Along with one of the large cushion stars, I discovered many starfish babies.

After rockpooling, we returned to retrieve our BRUV. Unfortunately, when we tried to pull it up out of the water, we noticed that part of the frame was caught on the rope, and we were at risk of breaking it. Eventually, we managed to pull it up using a mixture of the rope and a boat hook. Upon reviewing the footage, we realised that our setup had fallen backwards while under the water, so instead of filming the seabed, it had been pointing upwards the whole time!

Not many sea creatures were caught on camera today, which was disappointing. Then again, that’s what a pilot test is for! The camera worked and we learnt a lot about what to look out for in deployment sites. Hopefully our next try will be more successful. Given the weather today, I do not have any other exciting sightings to report! I will hopefully have some better news in my next blog post.
