I wrote to the list to mention that the phenomenon
of finding large clutches of chicks of Maned Ducks had been written about before.
Just in case some readers misunderstood why I was mentioning this, it is mainly
because some of the previous input was entertaining (and I believe I recall
some photo evidence). I thought those (perhaps newer contributors) making or reading
the new comments, may enjoy seeing some of the earlier comments as well, to add
to the story. Animal behaviour is often hard to explain unless there is
evidence of repeated occurrences of similar patterns to put it into a context. That
is the reason for saying it has been reported before.
I could say (I think obviously) there should
be no suggestion intended that it is not worth mentioning again, as further
evidence of the same thing. Similar explanation applies to similar comments
that may arise in other contexts.
