| Abstract: | The strength and specificity of attraction between mated pairs of red-bellied tamarins (Saguinus labiatus) were tested in the laboratory. Test individuals were placed in a choice situation in which they could indicate their preference,
by proximity and quality of behavior measures, to either their pair mate in an adjoining cage or an alternative in a second
adjoining cage (same-sex animal, opposite-sex animal, or an empty cage). The test animals showed a significant preference
to be in visual contact and proximity with their pair mates instead of the alternative when it was an animal of the same sex
as the test individual or an empty cage. However, when the choice was between their pair mate and an animal of the opposite
sex, no preference for their pair mate was apparent. No sex differences were found. It is concluded that attraction to a pair
mate is not sufficient to maintain a pair bond, and when pairs ofS. labiatus breed monogamously, the pair relationship is likely to be maintained, at least in part, through aggression between same-sex
individuals. |
