You , me , Arabian tea , dogs , cavalry , rabbits , deer , elephant and wads of other animals all make chocolate-brown crap ( mostof the time , anyway ) . What makes birds curve from the standard color palette and give rise inglorious and whitened poo ?
Birds ’ digestive scheme and spicy bit do n’t work exactly like ours or most other animals ' . Instead of pooping and micturate separately , they fundamentally do it all in one weird muss . Their kidney extract nitrogenous wastes from the bloodstream like other creature ’ do , but alternatively of releasing it as urea dissolved in urine , birds pass it in the form of uric acid . It come out as a snowy sort of goo because of the biochemical reactions that happen to process the waste so it can be safely excreted with minimal water loss .
The means it ’s pass is also a little weird compared to the balance of us . Most razz specie do n’t have “ traditional ” penis and vagina ( though there are somebizarre exceptions ) . Instead , both sexual urge have a cloaca — an all - purpose entrance and departure for the enteral , generative , and urinary tracts . It ’s used to expel waste , lay eggs and have sexual practice ( which , for raspberry , come about in the form of a “ cloacal osculation ” ) . This orificial multitasking explains the benighted bullseye that ’s often in the center of the white acid waste matter . That ’s the factual “ poop ” part , or crap . Because the acid and poop are exhaust at the same time from the same opening , but from two dissimilar corporal systems , they do n’t have much clock time to blend in , and you get a dame dropping with two distinct parts that looks like a poor adult male ’s Rorschach test .
The acidulous attribute of hiss poop are a detriment to your car ’s paint business , but it ’s extremely try after for what it can do to your face . peradventure notyourface , but certain celebrities go crank for bird poop facials , where Japanese Nightingale poop is sundry with Elmer Rice bran and body of water and used to exfoliate the tegument .
