Salt Lakes and Flamingoes

So, in real life flamingos live in shallow salty lakes and lagoons and estuaries that often don't have any vegetation and are very extreme environments. I think it could be cool to implement a swamp variation that spawns flamingos, but is a very harsh environment where most other mobs cannot spawn. The biome could happen only in very flat terrain and have lots of small pools, and have Salted Dirt blocks which can't be farmed.
