Macaw

Since rising temperatures cause more salt and macaws and all animals need salt to survive, in a rainforest it takes a while for salt to get there and by the time any salt gets here from precipitation or other things most of it is gone so macaws eat salt in the dirt in specific areas were back then it was more "salty". Rising sea levels could greatly affect macaws since they are more land and air animals. They could adapt to a similar way wood ducks stick their head and neck to get food from water also it could affect their body shape or feet. Eating will definitely play a major role if sea levels rise, their body will definitely have to adapt to get food from water.Too much water can kill some vegetation so macaws may have to resort to feeding on aquatic plants or animals.
