Found it, and you are quite right. It was Tony Huber's observation,
sent in a letter to Dr Rodionenko.
The article is "Life of Seed" in the Fall 2005 SIGNA, about the
various ways that iris seeds are distributed and the effect this has
had on the size of the natural ranges of different species.
It concludes that "ornithochory ... [is] most poorly studied" and that
the "report of T. Huber about distribution of I. versicolor seed by
Canadian geese ...... for the first time gives an information about
complicated interrelations in nature."
So, unless more has been discovered since 2005, that seems to be all
that is known.
