Question

why do birds excrete wastes in semi solid form​

Answer 1

$\huge\underline\red{Answer}$

Birds excrete that white pasty stuff instead of separately urinating and defecating like mammals do. Mammals turn it into urea and urinate it out. Birds and reptiles turn it into uric acid. Birds have a chamber called a cloaca where digestive wastes, uric acid, and eggs or sperm go before leaving the body.
