The time in any flight that presents the greatest hazards to seagulls is during take off and landing. At take off, it is because speed is related to the lift needed to leave for the seagull to rise up into the air. Lift for the seagull is the weakest at take off because full speed has not yet been made. When a seagull starts to land, lift becomes weakened because the speed of the bird is being reduced.
