The Civil Aviation Authority (CAA) has said bird strikes have risen at Glasgow, Aberdeen and Inverness airports over the past two years, with an increase in wild flocks and air traffic blamed.
Confirmed reports of bird strikes are on the increase throughout the UK, with 1529 reported last year – up from 1278 in 2009.
Airport operators insist the risks are remote, but they are not complacent about the dangers of the incidents.
Bird strikes have been blamed for bringing down huge aircraft in the past, including the incident in 2009 where an Airbus A320 was forced to ditch in the Hudson river in New York.
Glasgow Airport reported eight strikes this year involving large birds, up from the usual annual average of three.
Officials say more swans and geese may be migrating to Scotland, and some birds may be roosting in nearby industrial buildings.
The CAA figures show bird strikes at Inverness Airport increased from 24 in 2010 and 31 last year to 35 so far this year.
In Aberdeen reports fell from 37 to 27 in 2010 and 2011 respectively. But the number has reached 38 for 2012.
Prestwick Airport had a reduction in reported incidents, from 15 last year to eight so far this year.
