Interpretation

Bird flocks and migration are expected around the aerodrome from the runway northeast to southwest, from the surface to 3,000 m. Bird activity is expected from 0400 to 0600, with migration from 2200 to 2359, 0200 to 0700, and 1000 to 2000. There is an increased risk of birds crossing the runway extended centerline and of bird strikes during landing and takeoff; the aerodrome authority will use bird-dispersal methods, and crews should exercise caution.
