Individual identification by toe tipping and VIE tagging.
Each individual was marked by the removal of one phalanx and the injection of one VIE colour into one of the highlighted body parts (A). VIE codes are highlighted with blue frame. Each marking code indicates the side of the body (L: left, R: right). Additionally, toe-clip codes indicate the limb (F: forelimb, H: hind limb) and digit (according to proximity to the body), while VIE codes indicate the body part (A: upper arm, S: shin, F: foot). The applied VIE colours and whether or not they are fluorescent under ultraviolet lighting are indicated on the right. Example photos show LF-4 combined with RS-red (B) and RF-4 combined with LF-green (C) just after tagging. Exposure curves were applied for each image to facilitate pattern visibility.

Percentage of ambiguous and unambiguous identifications for each marking method, regardless of correctness of the identification.
Fig 2.
Identification success for marking by toe tipping, depending on the digit clipped (A) and the timing of checking the markings (B). Letters at the top of bar plots indicate statistically significant differences within each panel (groups with different letters differ at P < 0.05 after correcting for false-discovery rate).
Fig 3.
Identification success calculated in three different ways for marking by VIE tagging, depending on tag colour (panels A, C and E) and tagged body part (panels B, D and F).
Letters at the top of bar plots indicate statistically significant differences within each panel (groups with different letters differ at P < 0.01 after correcting for false-discovery rate).
