What are those birds at the top?
Huia, birds native to New Zealand.  This art is located on a wall near the Britomart train station/neighborhood in Auckland.

What do you mean, “a non-Kiwi kiwi”?
A person from New Zealand is called a “Kiwi”.  I’m not a New Zealander.  My nickname stems from my first year of high school, probably before I even really knew that New Zealanders were called Kiwis!  (My 9th grade class took a trip to Yosemite, and during a group bonding/environmental education game, my team was made of “kiwis”.  So there you have it!)
