They walk, they swim, they fly. These are the only three modes of travel* and seagulls can do them all.
Us? We are stuck on land. More importantly, we are stuck in society.
Seagulls and even creatures which have restricted travelling methods like fish or hares and, well, pretty much all creatures but humans, are free. They are truly free.
Free from greed: humans are the only creatures that kill for reasons other than food. We even waste food.
They are free from peer pressure. They are free from wearing masks. They are unchained from the burden of life us humans carry on our shoulders.
Most importantly, they don’t have to pretend to be someone they’re not. They are free and unchained from society.
*sorry, I thought about it long and hard, but no, time travel is not a recognised form of transport
