Dotted all over Hirta (and there are some on Boreray and Soay) are these domed structures. They are unique to St Kilda and are called cleits or cleitean, They are small stone sheds with a roof of a large flat stone covered with earth and turf. The walls are built of stones with little gaps between them. This means that the wind can whistle through and help things kept inside them dry and cool. In a windy place like St Kilda it's a perfect design for what some have called 'stone fridges'. They were used to store, amongst other things, salted seabirds, eggs and feathers, crops and peat and turf. There are 1,260 of them on Hirta and were built where they were needed and were owned individually rather than collectively. Today they are home to many birds, including Storm and Leach's petrels.

The most common flower on the slopes of Conachar was the Bog Pimpernel, which is delightful but not that common across the UK. It's quite a small flower with 5 striped petals: the leaves are even smaller. Look closely at the centre of the flower and you'll see something really interesting: there are 5 stamens with cream-coloured pollen and a single slightly longer stigma and these are surrounded by a mass of thin white staminal filaments which lack anthers. The Latin name is Anagallis tenella: Anagallis means 'to delight again' and refers to the reopening of the flowers each day when the sun shine, while tenalla means 'delicate and tender'. This really is a very delicate 'don't touch or else' wildflower: pick them at your peril and watch them fall apart as you do. So why would you? I love the precision of the Latin names for flowers. |

The native sheep of St Kilda is the Soay. Derived from domesticated sheep a long way back, these became feral on Soay. They are sure-footed and are particularly adept at surviving on the barren terrain of the islands. They have been exported to other sites, including Lundy Island in the Bristol Channel. Once upon a long time ago, Soay sheep at Beckenham provided me with anti-sera for the development of immunoassays. |

Just two of the many puffins we saw. We've seen thousands of them in various places but they never lose their attraction. And very attractive to the islanders they were too. One book I've read said that they ate dried puffins as a snack, rather like crisps. And why not? But I don't see Walkers marketing that flavour, although I can imagine Gary Lineker dressed up in a puffin suit. The puffin is much more than an orange beak and a portly manner as tracking birds with geolocators shows. Their life cycle is fascinating and well worth reading about. And here's a puffin-factoid that has stuck in my mind: the female puffin lays an egg that is 20% of the female bodyweight. That's equivalent to a 11 stone woman giving birth to a 30 lb baby. Ouch! |

The same goes for gannets. An elegant and acrobatic bird. This one is a young one as its plumage shows. |
|
See all those dots? Puffins every one. |
|
Cormorants. Lots of cormorants. Lots of noisy, smelly cormorants. Is there any smell more distinctive than that of guano, lots of guano? |

Stac an Armin, at 643 feet, is the highest sea stack in Scotland and, indeed, the British Isles. It really is an impressive sight close up and it hits you that people can actually land there. It was not inhabited year round and was used as a seasonal sea bird hunting ground by the St Kildans, climbing the rocks to collect eggs and young birds. Apparently it is still used for climbing as a recreational sport but strict rules exist to protect the bird habitats and breeding grounds. It is, after all, one of the largest gannetries in the UK. I should also mention that it has hosted an involuntary extended stays but more of that later. |

Gannets? You want gannets? There's plenty of them on Stac an Armin. For the St Kildans, this amounted to an avian supermarket and meant that they were adept at leaping from rock to rock to harvest the 'crop' at the appropriate time of the year. They were in tune with nature and they never took more than could be sustained. The present day large populations of birds are a testament to their guardianship. |

I mentioned an involuntary extended stay previously and it was not unknown for hunters to be stranded on the Stac for a while due to inclement weather. There is no set landing place as such and getting ashore meant leaping from a boat onto the rocks as the waves allow. You can see that this feat of acrobatics was very weather dependent and could only be done when the conditions allow. Back to the involuntary extended stay: the 'normal' length of stay was around a couple of weeks but the longest recorded period anyone ever spent on the island was about nine months. Three men and eight boys from Hirta were marooned here from about 15 August 1727 until 13 May 1728. As luck (or Sod's Law) would have it, Hirta suffered a smallpox outbreak while the eleven were on the stack and the settlement was almost wiped out. Consequently the surviving islanders were unable to man a boat and retrieve them and this had to wait until the following year when the numbers in the community had been supplemented by immigrants from other islands . Those on the Stac survived by fishing, catching birds and trapping water. They constructed a shelter which is still just about discernible when someone points it out to you. It's in the photograph, I think, but I can't make it out. Have a go and let me know if you can. |

A gaggle of Guillemots. |
|
Lots of Atlantic Grey Seals around as well. This one gave us a cursory glance before it slithered back into the water. |
|
Not sure what these gannets were looking at but I like looking at them. |

And we bid farewell to St Kilda, with Boreray to the right and Soay in the background I'll confess that I spent most of the trip outside. Normally I'm a pretty good sailor but this trip did make me feel rather queasy every now and then. Four hours of thumping from wave to wave was a bit much for me - but nothing that the fresh air couldn't help with. |
