A bird's kidneys function to filter waste products from the blood and concentrate them into the urinary waste to preserve water in the body.
Bird waste is typically referred to as Bird droppings.
Through their waste products, and through their abandoned nests, birds may be said to be composters. Specifically, animal waste products often include nitrogen, in the soluble form by which it can be used by soil food web critters, soil and plant roots. Additionally, bird nests tend to include what they recycle from nature. That means that once abandoned, the nests begin the process of breakdown that returns to nature what was taken from it.
Yes
they dont waste it they pik out what they like.
Not really, although it sometimes goes by other names. The anus is the part of the body of most animals that excretes waste products in solid (or mostly solid) form. Animals will also have a urethra through which liquid wastes are expelled. Birds have neither; instead, they have a "cloaca", from the Latin word for "sewer". (That's why bird mess is runny and splatters on your car; it's all mixed together.) But no matter what you call it, there has to be an excretory organ to eliminate wastes; otherwise, the animal will die.
Broken branches, twigs and leaves as well as animal, bird and insect droppings might be classified as waste products, but they biodegrade on the forest floor and add to the richness of the soil.
All waste from the toilets are stored in tanks that must be emptied on the ground. The waste water from the sinks, however are dumped in flight. The water is expelled from heated tubes that protrude out from the belly of the plane. The tubes are heated to prevent the water from freezing as it is being dumped.
