Main ornithologist finds no indicators of disturbance amongst seabirds on Eday, Orkney 

A research on seabird colonies carried out by ornithologist Dr. Roy Armstrong and ecologist Caitlin Henderson has discovered no indicators of disturbance because of current drone flights operated by Windracers to and from Eday in Orkney. The findings are important given drone firms need to serve Scotland’s distant island communities, the place quite a few delicate chicken species are situated.

Windracers, the UK-based self-flying cargo plane producer, commissioned the seabird colony disturbance research alongside its current drone supply trial in Orkney, which noticed  Windracers ULTRA – a sturdy, twin-engine fixed-wing plane with a 10-metre wingspan – shifting autonomously between the islands of Eday, Westray and North Ronaldsay in Orkney plenty of instances every week. 

Ornithologist Dr. Roy Armstrong and ecologist Caitlin Henderson carefully monitored plenty of seabird colonies earlier than, throughout and after drone flights over the Calf of Eday, an uninhabited island which helps 32 species of breeding birds and is designated as a Particular Safety Space (SPA) for its significance as a nesting space. This included the cormorant colony and nesting Fulmars, in addition to a wider vary of nesting seabirds across the cliffs to the North of the Calf of Eday – akin to guillemots, razorbills, kittiwakes and gulls.

The research discovered that neither the auditory nor visible affect of the drone brought about any opposed impact to the behaviour of any species throughout time of survey, though the taxiing drone appeared to draw foraging widespread gulls – a species identified to comply with agricultural equipment throughout hay chopping. The research did determine disturbances because of a passing sheep, some passers-by and a ship. 

Based on Dr. Armstrong, one of many nation’s most skilled ornithologists with over 30 years of economic expertise together with quite a few chicken surveys at and round UK airports, the statement that no species have been disturbed by the drone flights is per different observations of drone/chicken interactions. This consists of drone monitoring of gull breeding colonies by which breeding birds seem like oblivious to the presence of the drone. The ornithologist additionally identified the noise ranges produced by Windracers ULTRA are very low in contrast with industrial or army plane and wouldn’t be anticipated to supply an opposed affect. 

“The trials clearly demonstrated that there was no disturbance impact noticed on the chick rearing stage of a variety of species. This is a crucial stage as  disturbance has the potential to intervene with chick feeding and sheltering of chicks by adults throughout opposed climate situation,” mentioned Dr. Armstrong

“In continuous development and enchancment of ULTRA, Windracers is eager to grasp any potential impacts from our flights on chicken colonies and different wildlife within the areas the place we function. The findings of this research will little question be of reassurance to Orkney residents in addition to the birdwatching neighborhood around the globe,” feedback Rob Datson, Chief Operations Officer at Windracers.

The cargo supply trial utilizing Windracers ULTRA was a part of the Sustainable Aviation Check Setting (SATE) programme and was part-funded by the UK Analysis and Innovation (UKRI) Future Flight Problem, delivered by Innovate UK and the Financial and Social Analysis Council. Its purpose is to display readiness to function a industrial drone service that may transport significant payloads reliably, cost-effectively and sustainably for the good thing about communities in distant areas, such because the Highlands and Islands. 

The Civil Aviation Authority (CAA) lately introduced that SATE was amongst six tasks which have been chosen for trials to assist safely combine drones flying past visible line of sight (BVLOS) of their operator into UK airspace. Consortium accomplice Highland and Islands Airports Ltd (HIAL) – which additionally collaborated with Nature Scot’s Species on the Edge and the RSPB to ascertain a secure nesting habitat for the endangered Little Tern chicken at Islay Airport – will lead the mission together with Windracers. 

Windracers ULTRA – which has a helpful payload capability of as much as 100 kg and may journey middle-mile distances of as much as 1,000 km – is ready to take off, fly and land safely with out the necessity of a distant pilot due to its autopilot and mission management software program. Its methods are twin or triple redundant to make sure it will possibly fly safely in all circumstances.
