Sat down beside shallow pool in Tyto and won bit of trust from White-necked (Pacific) Heron (Ardea pacifica), which shows somewhat lopsided plumage on right wing (but looks fine in flight).
Bird walked towards me, feeding mostly on prey snatched from water before slowing and staring hard at insect in mud on bank.
Lightning stab and what may be young grasshopper is heron fodder. Bird then decided food is food and trust is trust but safety first is the golden rule. Slowly turned and foraged back the way it came. Typical behaviour from herons and egrets, which often commit to a particular target and allow an approach until they make their kill, after which they often unhurriedly fly off. Touch-feeders such as spoonbills don't have the sight of choice prey items tempting them to ignore intruders.
