Mostly urea, salts and excess water.
Urea is produced in the liver and enters the bloodstream. it is filtered by the kidneys into the urine. The urea molecule travels in the urine to the ureters, the bladder, and the urethra before being expelled via urination.
The urinary system filters waste from the blood. This waste includes urea, excess salts, and other toxins that are excreted as urine through the kidneys.
The two main wastes removed by the urinary system from the blood are urea and creatinine. Urea is a byproduct of protein metabolism, while creatinine is a waste product of muscle metabolism.
Birds, including eagles, do not have a separate urinary system. Instead, they have a single excretory system that filters out urea, which is then excreted as a white powder or paste along with the feces.
Urea and excess water are processed and excreted by the kidneys, which are part of the urinary system and not the digestive system.
