There's quite a few birds in the area that sound quite lovely. There's bellbirds and tuis that both enjoy the sweet sticky honeydew excretions from the various aphids and other insects that suck the sap from the trees in the bush. You can see some of the honeydew, and the black sooty mould on the tree trunks on the image to the left. With time to just sit and relax you're bound to see the bellbirds quite close to. Sadly, we were a bit short of time so most things were in a rush in an attempt to see as much as possible in the available time. Even so we saw bellbirds, tuis and robins.
