I spotted this guy, stalking his dinner in the estuary behind Rabbit Island, yesterday afternoon on my way home. I pulled the van over to the side of the road and took this picture through the window, so I didn't spook him, and break that intense concentration.
It is a White Heron (Egretta alba modesta to be precise) or Kotuku (NZ Maori name). They are rare (only about 15 breeding pair) in New Zealand which just adds to their mystic. Another species for my collection.
