Because birds use more energy to convert toxins filtered by kidney to uric acid and pop that out to safe water.
Mamals convert it to urea which is then peed out, which looses the body some water, but requires less calorie.
Fish don’t do that at all, they are basically constantly peing out whatever their kidney is filtering, which requires the least amount of energy but a constant supply of water.
ps.: the acid part in uric acid is why bird shit is so nasty to buildings and car paint etc. if it is not cleaned fast enough.
Fick Trinkalkohol, alles was dagegen gemacht wird find ich erstmal gut.
Alkohol ist ein Desinfektions- und Reinigungsmittel, man kippt ja auch keine Bleiche in sich rein (wobei es auch Leute gibt die das machen…).
