NATO jets scrambled over Lithuania after birds mistaken for drone

Lithuania briefly closed Vilnius airport and NATO scrambled fighter aircraft after a suspected drone was reported near the capital, before authorities determined that the object was a flock of birds.

The airport reopened after approximately 38 minutes, limiting the operational disruption. The alert nevertheless triggered a security response because unidentified objects near civilian airspace can present both aviation and national-security risks.

Lithuanian authorities initially treated the sighting as a possible unmanned aircraft. NATO aircraft assigned to protect allied airspace in the Baltic region were summoned while officials assessed the report.

The subsequent identification of a flock of birds meant that the incident was a false alarm, not a confirmed airspace violation. No hostile drone was recovered or independently observed, and there was no reported attack.

Lithuania, Latvia and Estonia do not operate their own full-time fighter fleets for air policing. NATO allies rotate aircraft and personnel through the region to monitor and respond to airspace incidents. The mission has taken on increased importance since Russia’s full-scale invasion of Ukraine.

Civilian airports across Europe have also strengthened procedures for suspected drones. Even small unmanned systems can force temporary closures because of collision risks, and authorities often have to make decisions before an object’s identity is certain.

The Vilnius case illustrates the difficulty of distinguishing drones from birds or other objects at distance, particularly when a report is based on brief visual observation. False alarms can still require a real response because the cost of failing to investigate a genuine threat may be high.

Officials did not report injuries or damage. The closure was lifted once the assessment established that the object did not pose a drone threat.

The event should therefore be described precisely: NATO jets were scrambled in response to a suspected drone, but Lithuanian authorities later said the sighting was a flock of birds. Presenting it as a confirmed drone incursion would be inaccurate.

Lithuania’s National Crisis Management Centre said the initial radar marks produced by birds and drones can appear similar. A NATO jet made the visual identification after taking off from Šiauliai in northern Lithuania, where the Italian Air Force was operating as part of the alliance’s Baltic mission.

The Vilnius marathon continued during the alert, organisers told Reuters. The short airport closure and rapid reopening provide the measurable operational consequences: authorities imposed a precautionary restriction, verified the object and lifted the warning once the identification was complete.

The alert came amid concern about military drones entering or approaching the airspace of Finland and the Baltic states during the war in Ukraine. That background explains the rapid response, but Lithuanian officials did not link the flock of birds to any hostile activity.

Airport authorities did not report injuries, aircraft damage or a prolonged diversion programme. The event ended once the NATO pilot’s visual check resolved the discrepancy between the initial radar impression and the object’s identity.
