Bogdarina S.V., Evdokimova S.E. 2013. Marking bats with coloured collars for remote identification of individuals in the group. ­ Plecotus et al. 15-16: 70­75. For long-term ethological observations of mammals, particularly bats, in stationary conditions you must have clear individual markers visible and recognizable at a distance of several meters. We designed collars which are securely fixed to the animal's neck, do not bother it, and have a rich variety of colours. The basis of the collar is a zip tie for electric cables. The length of the tie is selected depending on the size of the animal. Commercial sets of ties can be already compose d of ties of several col ours. In addition, the cable ties can be encased into heat-shrink tubings of other col ours. With a large number of individuals in the gr oup there might appear a need to choose s uch col ours and their combinati ons that are well distinguishable one fr om the other at a distance and in conditi ons of l ow illuminati on. For this purp ose, col our heat -shrink tubings can be cut in pieces, which are patterned in striped collars, or holes of various shapes and sizes cut in the tube make the tie of a contrasting colour visible through them. These colourful constructions are clearly visible from a distance. To fix this design, you need to hold the collar over the heat source to shrink the tubing on the tie. This method was tested on four groups of Egyptean fruit bats in the Leningrad and Moscow Zoos. After an adaptation period of one to several days, no significant inconveniences to the animals were noticed. The maximal duration of wearing the collar by an animal is more than four years.
