geoffroy's tamarin generally avoids sympatric small and medium size monkey species such as the white-headed capuchin and the panamanian night monkey. avoidance is spatial with respect to the capuchin, and temporal in the case of the night monkey, since geoffroy's tamarin is only active during daylight hours and the panamanian night monkey is only active at night. geoffroy's tamarin is rarely observed in the vicinity of squirrels, although this appears to be the result of the squirrels avoiding interactions with the larger tamarins. geoffroy's tamarin generally attempts to escape when birds of prey approach, regardless of whether the bird presents a true danger. however, the tamarins ignore one bird of prey, the double-toothed kite, which sometimes follows the tamarins in an apparent effort to feed on small animals disturbed by the tamarins.
