Its interesting how Mauro's "Drivel" has turned into serious
discussion within two emails - perhaps the occasional light-hearted
email is needed to trigger other discussions Mauro!

Ken:
As you already know, the Cetti Warbler of southern Europe, is reported
to live in "dense low vegetation" and has the habitat of cocking its tail
downwards. This behaviour is most likely a visual display performed at
close range while hidden in the swamp. I proposee that the male "intends"
to display the fine markings under its tail. Why? In Zebra Finches the
fine streaking on the breast is used by females to ascertain the health of
the male - any disruption of the streaking pattern indicates a problem
with feather development. The same process could apply to male Cetti
Warblers.
Care to elaborate further?
Cheers, Jim
