| Unmanned aerial vehicles that recharge themselves automatically. |
In the story, the tracer-birds are used to spy upon the novel's main character. It is noteworthy that Zelazny hit upon a useable way for UAVs (Unmanned aerial vehicles) to do solar charging automatically.
| The dark birdforms dotted the mountaintops like statues of prehistoric beasts, wings outspread. Had there been an eye to observe them, it might not even have noted their minute, tropism-like pursuit of the sun across the sky as they recharged their batteries for the night's flight. |

The earliest reference that I know of for a robot that can charge itself is from the 1960 short story Callahan and the Wheelies by Stephen Barr. See the article for the self-charging robot.
