I am fairly sure that all orders apart from passerines have anything from
fully functional to vestigial salt glands behind the eyes. This would be
very useful to Australian birds given the large amount of salt found in
water both estuarine and inland. Having said that I have also see SC
Cockatoos foraging around on estuarine rocks (e.g. below Audley Weir in RNP)
and apparently dipping their bills - closer examination showed that they
were, of course, sampling Sydney Rock oyster au natural. Ciao
