You'll likely see the resident Kingfishers (or Fishes, depending on how quick you are) as there are usually a few couples that hang around here. Maybe you'll see the little Forest Kingfishers who like this area. They reportedly nest in arboreal termitaria (termite nests in trees) ~ 4 - 12 m above the ground. Each member of a pair apparently flies straight at the nest site from several metres away, with their bills pointed forward like a bullet, chipping away some of the 'cement' with each impact to make their nest - happy for any ornithologists to put me right if this is awry. There's also the regular Kooka variety to be seen along with other avian types .
A few other caches hereabouts as well so you could make an outing of it.
