Geoffrey raises a good point. There are several
places in the gardens where birds can walk in for a drink (and Bronzewings do)
but Rosellas rarely visit them.
When the Swifties visited Mt Majura I was surprised
by their preference for the more exposed top of the drain as a drinking site.
Many more birds of all species drink from that drain than from the dams on the
reserve.
Perhaps they recognise these sources as cleaner ie.
free of worms and other parasites?
If anything the tap water would be lower in salt
content than dam water.
