As I walked around the corner of the California Academy of Sciences on my morning exercise walk, I was surprised by a roar. There was an animatronic dinosaur (T-Rex?) swaying in the side yard. This was part of Dino Days https://www.calacademy.org/exhibits/dino-days . I dunno if they leave the animatronics running 24/7, but it was going as of 8 this morning.

The animatronics were moving kinda slow+stately; not exactly what I'd expect of bird relatives. I dunno if this motion reflects how we think dinosaurs move vs. slow so that the animatronics don't fall apart from flopping around too much for a few weeks.
