I once saw a bird program reset like this.
A pigeon was doing his big fancy fance for a partner. But she walked behind an obstacle while his back was turned. When he completed the 360, there was no female.
The poor fella just stood there for some time then went pecking the ground, as if that is what he was doing.
Did he feel shame? Did he ever realize where the female went? Did he remember what he was doing a moment ago?
