I now know to go outside and look for cranes.
If delegating probably wise to specify construction cranes otherwise your twitcher PYI might pop back to inform you "sorry boss no cranes; some scruffy ducks and tatty bin turkeys."
I was once instructed to follow the highway for about 50 km and turn left at the giant moa. While that area abounded in giant bananas, giant pineapples and such like, I was puzzled why anyone would erect a giant model of an extinct New Zealand flightless bird in subtropical Australia - the native non extinct emu would make more sense.
Never found the moa. Understandable. It was of course the giant mower. (Alias lawn tractor.)
