Acidity of Bird Droppings?

Hi,

Does anyone have info on the acidity of bird droppings? And which commonly found birds have the most acidic droppings?

Many thanks in advance!

 

  • Hi and welcome

    Bird droppings normally consist of a mix of "Number 1s" (cellular waste) and "Number 2's" (undigested food residues). It all gets mixed up in the cloaca and expelled.

    Most birds operate at low water levels (it's heavy to transport by air) so the white component of droppings is a thick paste of uric acid. This can get acidic enough to wrinkle car paintwork. I speak from experience here.

    I'm not aware of any research on which species kick out the urates with the lowest ph. I'd imagine that much depends on diet.

    Every day a little more irate about bird of prey persecution, and I have a cat - Got a problem with that?

    I think seabirds have very acidic droppings, but thats the extent of my knowledge!

    Couldn't tell you the acidity of bird droppings but years ago I used to valet cars for a living and can honestly say that I have witnessed many a car ruined by bird droppings..... If it gets baked on by the sun it actually eats it's way into the paint leaving permanent damage! So if you get droppings on your car wash it off straight away!!

  • Hi MS

    Bird droppings do indeed contain uric acid, that can eat through steel.
