I'm a hobby photographer and I've noticed some patterns in the bird flights, so I tried to poke a bit into the aviation terminology for it. Phalacrocorax carbo does this movement similar to the attacker's
3 in the Displacement roll when declining just slightly above the water and then it pulls itself up slightly by doing this roll first, then slight pitch movement to continue the declining curve but to also gain some altitude while braking the movement and afterwards switches to gliding above the water.
Sometimes these movements are seen in action movies, so I think there might be an aviation term for it although perhaps only for the full "fighter maneuvers". Any ideas?
Example with the bird's flight trajectory:
Edit: I think the wind is coming under the bird's chest or from the side and I don't think I've ever seen a bird utilizing the same pattern in windless or in very weak wind environment (in those cases it was mainly gliding without turns or climbing).
