“…Squeeze cages also reduced the risk of injury to the handler by minimizing physical contact between animal and handler (i.e., animal always in trap or cage, squeeze cage manipulated through handles set back from cage surface). Additionally, temporary marking with dyes and inks has proven effective in many previous studies with no recorded adverse physiological effects [8,18,19]. We attempted fur clipping as an alternative temporary marking technique with little success.…”

We evaluated squeeze cages and water-soluble inks and dyes as methods for handling and marking of meso-mammals in a short-term capturerecapture study. Study animals exhibited no adverse physiological impacts from capture or marking techniques. We also observed no negative impacts on trap success for the duration of the study. We found these methods quick (5 minutes maximum hold time), safe (no observed injuries of animals or researchers) and reliable (effective marking and mark retention for a minimum of 12 days).

“…Three nests were monitored using nest cameras for a minimum of 72 hours during the field season of 2016, capturing images every minute. A small patch of black hair-dye (Ellis and Ellis 1975) was applied to the uppermost part of each wing of one parent at each nest, allowing us to distinguish between parents.…”

“…Nyanzol-D (Albinal Dyestuff Inc., Jersey City, NJ), a nontoxic black dye, was sprayed on the tail of the subjects by means of a ''spray gun'' (Hasbro Super Soaker Max-D 4000 Pawtuckat, RI) [Ellis & Ellis, 1975;Isbell et al, 1998] with a range of 2-3 m in 2002. A Hudson Trombone tree and shrub sprayer (model 61224, Hastings, MN; available through www.rittenhouse.ca) with a range of 2-5 m was used in 2003.…”

Individuals' behaviors following dye-marking in wild black-and-white colobus (Colobus vellerosus)

2005

The ability to recognize individuals is a prerequisite for analyzing social relationships. We marked five adult and subadult Colobus vellerosus (three in 2002, and two in 2003) at the Boabeng Fiema Monkey Sanctuary, Ghana, to assess the feasibility of dye-marking black-and-white colobus, describe their reactions, and compare some of their behaviors with those of unmarked individuals. We used Nyanzol-D, a nontoxic black dye sprayed on the white tail (or white thigh) of the animal with a spray gun or a tree sprayer. Reactions to the marking procedure ranged from moving away and staring at the observer, without interruption in feeding (in one subject), to fleeing about 5 m away (in four subjects). In 234 hr of ad libitum observations (in 2002 and 2003), marks were scratched or otherwise were the object of attention from the bearer or other individuals on only one occasion. In 2002 we collected 22 hr of observations on the three marked monkeys and some unmarked monkeys in 10-min focal samples. Neither the marked nor the unmarked animals attended to the marks during focal samples. Marked and unmarked individuals displayed similar rates of displacement activities (autogrooming, scratching, and yawning). The proportion of scans with at least one near neighbor varied between marked and unmarked subjects, but the direction of the difference was not the same between males and females. The only aggression observed was displacements, and only in one comparison (out of four) did a difference emerge: the marked subadult male received more displacements than the unmarked males. Overall, marked and unmarked individuals did not differ consistently in our measures. Examination of the potential effects of marking should continue, since changes in pelage coloration may have longer-term social effects in species that rely largely on vision.
