Flight Trainer for Albatross is one of the best names I've come across for a public artwork. This 2004 sculpture by Greer Twiss was donated by the Auckland City Sculpture Trust, and unveiled 9 August 2004 on Quay Street, by the harbour. From here:
The sculpture comprises three large albatross being supported in a flight frame and one at ground level. It is constructed of stainless steel and stands six metres high and three metres wide. Auckland-born artist Greer Twiss has designed the artwork to explore the relationship between land, sea and air and between man and nature. It is also a metaphor for the support needed for endangered birds like the albatross. The stainless steel structure will be robust enough for the waterfront environment and has links with the boats and activity in the area.
