It was regarded as cleansing agent. Natural history Hares are a common site on the Kilmaurs road near the Townhead of Lambroughton old entrance, but rabbits are a rarity hereabouts. Red foxes can be seen and heard in the woods by the Annick and migrating geese use the fields as a migration stop. Lapwings are an annual visitor as are the swallows and house martins which nest in the buildings of East Lambroughton farm. Other animals present include pipistrelle bats, moles, hedgehogs, common toads, kestrels, treecreepers, ravens, wagtails, house sparrows, blue tits, great tits, pheasants, common snipe, wrens, buzzards, chaffinches, blackbirds, greenfinches, and rooks. The rare hummingbird hawk-moth was seen near the Lambroughton Crossroads in 1985 and Duncan McNaught also recorded this species in 1912. The Stewarton flower The Stewarton flower, named for its local abundance by the Kilmarnock Glenfield Ramblers, is otherwise known as pink purslane (Claytonia sibirica) is found in damp areas. This plant was introduced from North America, quite possibly at the Lainshaw Estate for in the Anderson Plantation it was in 1997 almost the dominant undergrowth species. The white flowered variety was introduced here and the normal pink variety spread from elsewhere. As far away as Dalgarven Mill the white flowered variety still dominates. The plant is very adept at reproducing by asexual plantlets and this maintains the white gene pool around Stewarton. The pink variety has not been able to predominate here, unlike almost everywhere else in the lowlands of Scotland, England and Wales. Barony of Roberton Robertson mentions this barony, once part of the Barony of Kilmaurs, which ran from Kilmaurs south to the River Irvine. It had no manor house and belonged to the Eglinton family latterly. Hugh Montgomerie, Ist Earl of Eglinton, had a charter on 3 February 1499 from James V of the £40 lands of old extent of Roberton in Cunninghame. These lands were part of the Lands and Barony of Ardrossan at one time; the following properties were part of the barony: parts of Kilmaurs, Knockentiber, Craig, Gatehead, Woodhills, Greenhill, Altonhill, Plann, Hayside, Thorntoun, Rash-hill Park, Milton, Windyedge, Fardelhill, Muirfields, Corsehouse. Smith states that Roberton castle belonged to the Cunninghames, but had been completely rooted out by the 1890s. Thorntoun Estate Thorntoun house and estate was part of the ancient Barony of Robertoun and is first recorded as belonging to a branch of the Montgomeries, descended from Murthhaw Montgomery,
