This is a wetland delta that lies below the mountain range that divides the East Catland continent horizontally. It is not one singular river delta but a high concentration of many that make up an often saturated flat zone built up by fine sedimentary deposition near and on the coastline. The climate ranges between tropical and warm temperate, depending on latitude and elevation. Salinity is far less than sea water, but depending on elevation and closeness to the sea, mixing can occur with the tides causing water to have a brackish quality.

Bobbers soar above in search of prey (mice, lizards, small birds, fish and invertebrates) or carrion. Across much of East Catland and it's two subdivides bobbers are common scavenging birds but only where there is a current supply of water, either sea water or fresh water. Bobbers have highly waterproof feathers and can sit on top of the water, balancing upright on their chests, and can take off into flight from the water. This advantage makes water a safe place for them when there are threatening predators lurking around in the grass. But the water isn't a completely safe place, even though it can sometimes be safer than roosting on land. Fish also lurk which can sometimes rarely grow large enough to eat the bobbers.

She has done this many times before. She knows that she needs to be still and silent to blend into the background. Her prey will come within reach as long as she is willing to wait for the right moment. No need to waste energy in the heat chasing them like a manic kitten. So she stands like a statue. The delta grass sparrow start feeding on the young grains near by, no longer aware of the cat in their midst. The cat's mind is in tune to the rhythmic chirping back and forth between the tiny birds. She's ready to strike and feels the moment will be soon...

There's a sudden rustling of grass and a thrump-thrump-thrump of feet on the soft sediment. Before the cat can even register what just happened, her hyperactive kitten plops into the water.

The kitten immediately begins slamming her paws down hard in desperate attempts to grab the fish that are hopelessly out of her reach, and swimming away at greater speed.

The kitten's mother watches her target juvenile eeltrout swim away from her. It would only have been a snack, but still a suitable reward for the time she had waited. 

And after all that, the kitten has the attitude!
