Monkeys need to avoid predators such as big cats and birds of prey in the ecosystem to ensure their safety. They also need to be cautious of other territorial or aggressive animals that may pose a threat to them. Additionally, monkeys should avoid areas with limited food sources or where human activities may disrupt their natural behavior.

Food, Water, Sunlight, Habitat, and Air.
You NEED to avoid any pets or loud noises.
Different birds require different beaks and mouth-parts depending on their diet. Birds that eat meat need heavy, powerful beaks, nectar-feeding birds need long, thin beaks, etc. Beaks can also be used to attract a mate.
By sheer definition, the "system", implies, "parts". Ecology needs a system to keep it alive and running.
some animals might not get what they need
Who says birds don't poop in water! Seagulls do! I know ... got sprayed by one last summer. Yuk! Birds as a whole can and do poop in water if they happen to need to go when they are near water. But, pet parrots (whether near your pool or not)a parrot will tend to avoid pooping where they sleep and where they eat if they are provided with sufficient space to be able to easily avoid having to do so.
Birds need a lot of food for energy.
Yes birds do need beaks and feathers.
