Barn Owls at Ardgrain
Ardgrain is home to Barn Owls, which live in the adjacent barns. A dedicated Barn Owl box has been fitted high up in the tall Dutch barn, on-site, providing the Barn Owls with a permanent home. Our resident Barn Owls at Ardgrain often trip the outside security lights in the evenings, alerting us to their presence as they head out hunting once twilight falls. If we have our bedroom window open at night we hear their distinctive banshee calls as they search for mice, voles and other small mammals in the fields, and we have on occasion seen three Barn Owls together heading out towards Ellon, hunting at dusk.

Barn Owls are sometimes called Ghost Owls from their white undersides, which flash up suddenly as the owl takes to the wing. Other common names used worldwide are the Church Owl, Golden Owl, Rat Owl, Stone Owl, and Screech Owl.

Barn Owls help to control the rodent population, and are considered a farmers friend. An adult Barn Owl will capture up to seven rodents in a single evening. For their weight, Barn Owls consume more rodents than any other animal; with a young family, a pair of nesting Barn Owls can eat over one thousand rodents a year.

The adjacent farms to Nether Ardgrain, at Upper Ardgrain and North Ardgrain also have Barn Owl roosting boxes. In 2007 there were 6 eggs and 5 eggs laid by Barn Owls in these two roosting sites. Of these 5 and 4 eggs hatched in each, and all the chicks are doing well.

Telltale markers of Barn Owl activity can be regularly seen at Ardgrain. Owl pellets, full of rodent bones litter the barn floors, and the distinctive white droppings on high beams again confirm their presence.

Barn Owls throughout Scotland are in decline - they roost in the same places throughout their lives, and very often these habitats are removed, which displaces the Barn Owls. Without a nest, the Barn Owl lines slowly die out. Barn Owls often have a few select sites as roosts, and move between these during the year depending on the seasons and the available food. The Barn Owls at Ardgrain sometimes disappear for a few weeks at a time, as they move between nearby roosts and hunting grounds.

In the UK, there are estimated to be only 4400 breeding pairs of Barn Owls remaining. It is rare to have such a well established colony of Barn Owls spread between three sites, especially when Barn Owl roosting sites are in decline throughout Scotland. For example, only five breeding pairs remain in the countryside surrounding Edinburgh. Outdated farming practices, the removal of hunting and roosting habitats, and possibly even siting windfarms in environmentally sensitive areas have all had a negative impact on Barn Owl numbers in the UK over the years. Government efforts and initiatives are starting to reverse the trend.

Barn Owl numbers have stabilised in the UK and are hoped to increase slowly over the next decade. But for the Barn Owls at Ardgrain, the future is not looking so promising. A recent planning application at Ardgrain to convert three steadings into a residential house necessitates the removal of the Dutch barn, and with it the Barn Owl roosting box. No provision has been made to re-home the Barn owls at Ardgrain, and the entire Ardgrain colony is seriously under threat. The laws sadly didn't go far enough to protect the Ardgrain Barn Owl population, and Barn Owls in the UK will continue to struggle if sensitive habitats are allowed to be converted and developed.
More information on the planning application which will remove the Barn Owl habitat at Ardgrain can be found on the historic planning pages.
