Traditionally these huge colonies are counted by aerial photography, and only really need a detailed count about once a decade. With these birds being impacted extremely badly by HPAI in 2022 and 2023, new counts are now being undertaken by drone, which is a lot easier (in theory) and cheaper than paying for dedicated photography from an aircraft. I've never carried out drone photography of cliff nesters so was asked if I'd like to help out with the count at Ailsa Craig, a lump of volcanic rock 16km (10 miles) off the coast of Ayrshire in South West Scotland.

Ailsa Craig is famed for being the source of the finest granite for making Curling Stones. A local company holds the sole licence to quarry here, and takes granite off the island about once a decade, most recently just this winter and youtuber Ruth Aisling made a [fantastically informative video about the whole process](https://youtu.be/lTjOoeR0iFY) so you can watch that rather than me try to explain.

| Ailsa Craig viewed on approach from the boat, the lighthouse and assorted buildings around it can be seen above a rocky beach. Behind them the more grassy, but still steep, southern slopes of the rock rise above them. |

The boat trip is about an hour out of Girvan, and includes a circuit of the island so we could see the dramatic cliffs rising out of the water, covered in nesting seabirds - Gannets are the most obvious, but colonies of guillemots and razorbills, kittiwakes, and fulmar, and on some of the steep grassy slopes, puffins ambling about between their burrows. Tysties (black guillemots) were on the water, although I couldn't spot any on the cliffs.

Once on the island, we pitched our tents by the old gas works. This was where coal gas was generated to power the lighthouse and foghorns until 1911, when the lamp was switched to parafin. The flat part of the island is covered in remains from both the lighthouse and quarrying infrastructure, with a 3-foot gauge rail for the lighthouse still in place, and plenty of tracks and evidence of quarrying. The lighthouse is still operational, and being painted by three workmen when we were on the island.

In the sunshine, we walked from the lighthouse clockwise along the track left by this winter's rock extraction, we passed the south foghorn, on top of a concrete dome and with compressed air cannisters rusting alongside. Huge boulders litter the shore line, we walked as far as "Trammins" and flew the drone to take photographs of the gannets nesting on the 200m high cliffs towering above.

I slept very well in my tent, and we were up at 6 but had to wait for the low cloud to shift and the tide to go out a little before walking anti-clockwise this time, following a trackway that carried the piped gas to power the north foghorn. In places it bridged inlets, these were rusted away so we dropped to the beach then climbed back up the other side.

| A narrow concrete walkway crosses the rocky beach. Where there are narrow inlets in the steep rock, it is bridged with rotten wooden and partiually missing slats across rusted metal framework. |

| A pile of granite rocks, smooth and grey, but many of them are cylindrical shaped. Each cylinder is about 30 cm in diameter and a little taller lengthwise. There's also some rusted bits of old machinery. |

We also stopped at the remains of the old North Quarry, and puzzled a bit at vast piles of stone with cylinders cut out, and the stone cylinders themselves, before it clicked that these were where they used to cut out the basic curling stone shape before shipping them off the island, presumably easier to do so and ship off here before larger boats and trucks made taking whole boulders off the easiest method.

Tempted to take a "raw" curling stone back with us but a little heavy for our backpack. We walked on, past the northern foghorn, and then through a very low colony of Auks, until we were underneath the main Gannetry on the vast cliffs, and were able to photograph them again with the drone.

The south-west point of Ailsa Craig holds a deep seacave that makes walking a loop of the island impossible, so we walked back the way we came and found we still had a good few hours before the boat. I climbed the incredibly steep and loose path through thick bracken, reaching the Castle (A 16th century tower)

| The northern foghorn, another tall concrete dome with a rsuted horn on top. This time I am stood on the walkway, and we can see the rusted old compressed air tanks to the left of the walkway, and at the end, a steep and rusted ladder climbing up to an empty doorway in the dome, through which we can see daylight and some more rusted machinery inside. There's a steep cliff to the left and the rocky beach falls away to the right. |

We passed a dry seacave, and had a look inside - nothign but bones of seals and rabbits, but then we spotted a few pieces of graffiti, from 1923 and 1886.

We carried out the drone survey, and then returned back. The south-west point of Ailsa Craig holds a deep seacave that makes walking a loop of the island impossible, so we walked back the way we came, passing a simple wooden structure that looked like a very old watcher's hide?

And alongside it, a tanked spring, one of four on the island. (the main source of water for our trip was me knocking at the lighthouse and asking if we could have a bottle of water when we realised we hadn't brought enough)

| Just above the castle is a concrete basin in the dense ferns on the slope. It's fed by a spring, this is Castle Spring (obvs) |

Through the bracken, I could follow the path a little further, but then lost it int he bracken on the rocky slope. I didn't feel like going any further, so went back to the castle for a sandwich and a chat with a kayaker who had just arrived.

After returning down the hill, I explored the buildings more, and chatted with daytrippers who'd been dropped off. A fast private charter returned - we'd spoken to the skipper last night too, a local man, who'd been coming out the Craig since he was 9 years old. He told some tall tales about the lighthouse keepers, and how the current owner of the old lighthouse buildings - these are seperate ownership to the island - is applying for planning to build 40 glamping pods out here for holidaying, which I don't think anyone thinks is a good idea. I was more dismayed about how the buildings that were still in use (the old lighthouse cottages and the Quarry Manager's Cottage, used by the local ringing group) had been left to collapse. I understand the ringers lacking the funds to maintain their building, but the multi-millionaire who owns the cottages could at least keep them in good condition. The rest of the buildings were little more than atmospheric ruins.
After returning down the hill, I explored the buildings more, and chatted with daytrippers (birders) who'd been dropped off. The old Quarry Master's Cottage was used by the local ringing group until the roof collapsed, which is a real shame, but I imagine the costs of maintaining and repairing buildings out here is pretty significant.

| Inside the small white building. The roof has collapsed and daylight can be seen on the bare stone wall where the plaster has fallen off. Next to it is a fireplace, still with lamps and candleholders on the manelpiece. A coat is hung on the wall, and a chair with a floral pattern sites at a table on which is a table cloth and various unidentifiable things, jars, a bottle, a wooden puffin, books. The collapsed ceiling covers the rest of the floor and bracken grows up at the back of the room. |

What a great trip out! I feel very lucky to have been allowed to camp on the island and have the time to explore it fully. You can get a trip out from the port of Girvan in Ayrshire, it's about an hour to the island, you get 2 hours ashore, and then a trip around the island and back again. Very much worthwhile.
