I spent a few days at a caravan oark at Berri over the week end. I was pleasantly surprised by the numbers of duck feeding on the grassy sites put aside for tents and unpowered vehicles.
Looking at them, it made me reflect. Yes we know they breed in trees, but do they roost in them? It would seem to me that if you can do the one, why not do the other? It would keep them away from the foxes and from competing with other birds for roosting sites. Any one know?
