Kingfisher (Alcedinidae family) (not the beer sadly) is known for their colourful bright feathers which primarily hunt for fishes, and some species eat insects, reptiles and amphibians.
Famously known for their hunting skills where their dive into water can reach utpo 100 kph are popular pets too.
They eat 60% of their body weight everyday (Maybe I am a kingfisher too)
This makes them very territorial as they need to obtain large amounts of food from their limited surroundings.
And the bullet train is also inspired by Kingfishers
