The mention of rank grass below reminded me that I've been wondering
exactly what this term means.  I've seen it mentioned in the field
guides as habitat for some species, but haven't been able to find a
proper definition for it, other than that certain species are considered
to be rank grasses.

I have been monitoring this nest - they are Purple Swamphens, they (both
a male and female) commenced incubating nuts pre 8th Jan and are still
sitting!!  I have more photos and considering writing a short note for
publication, the nest is certainly not the typical Swamphen nest of reed
stem sections but rather a bowl in somewhat rank grass - that has since
been mowed (slasher raised to avoid slashing nest!).  I suspect they may
lost a clutch of eggs(??) and the nuts are substitutes (?).   I dont
whether they gathered the nuts or whether the nuts may have accumulated
in a depression which may then have enticed them to incubate(?).

There is a recent report of Black swans incubation glass bottles (see
Aus Field Ornithology Vol.23 No1. March 2006).
