I just do, the same way I can remember most (not all) scenes of a given television episode forever after seeing it once. It is just the nature of intelligence. Memory in not observability though, and so more can be gained from a second reading/viewing.

Chimpanzees, for example, have photographic memory. They remember absolutely everything. Photographic memory is not likely for corvids but their memory may well be superior to humans as well. In that regard they are more intelligent than humans but lack the tools in their toolbox to achieve superior mechanical or functional output.
