Weasel footprints on tracking paper with weta footprints.
The weasel footprints are on the left. Other evidence as well as footprints is needed to confirm weasel identification because, while weasel footprints are typically smaller than those of stoat's, there can be overlap in size with juvenile stoats.
These particular prints were left by a female weasel that somehow got into Zealandia wildlife sanctuary (see On the Case story). Fur in the ink precluded the possiblity that the prints were those of a tuatara (which live at Zealandia), whjose footprints can look quite similar.
