Two Weeks Ago at AMS,
Taxied from Hotel stands with permission to cross 36C for 36L departure. Reported a flock of 12 swans (flying perfect vic formation) at 30 feet flying south-north right up the middle of 36C. Tried for 3 mins to talk ATCs eyes onto them with no success. Seemed to me a lack of concern to what I considered a major hazard.
Disconcerting!
