E Rosellas eating ash

[Paul Taylor <>]

Ash is alkaline due to compounds like sodium and potassium carbonate
(hence the name "potash"), so could be used by the rosellas as an antacid.

Certain layers of the strata exposed in the State Circle cutting next to
New Parliament House in Canberra are eaten by the local birds.  My guess
is it may contain kaolin (commonly used for settling an upset stomach),
or it's a source of calcium.
