• Special behavioural observations (<strong>in</strong>tra- or <strong>in</strong>terspecific): Interspecific <strong>in</strong>teractions<br />

only on the ground, <strong>in</strong>itiated by the marmosets. Compared to the tamar<strong>in</strong>s (see association<br />

2 above), marmosets felt less disturbed by the agoutis.<br />

• Problems and risks (animals, technical, vet. medical): Marmosets tried to get the<br />

food placed for the agoutis on the ground. Agoutis defended their food and dur<strong>in</strong>g these aggressive<br />

encounters one marmoset was bitten.<br />

• Special measures at the beg<strong>in</strong>n<strong>in</strong>g <strong>of</strong> association: unknown<br />

• Special behavioural observations (<strong>in</strong>tra- or <strong>in</strong>terspecific): C. apera obviously suffered<br />

from the marmosets curiosity (aggression?) and were displaced by the primates easily.<br />

Interspecific <strong>in</strong>teractions occurred on the ground, when marmosets took the food placed<br />

for C. apera - before or after they chased them. Marmosets did not feel disturbed at all (but<br />

see also association 2 for red-bellied tamar<strong>in</strong>s).<br />

• Problems and risks (animals, technical, vet. medical): A comparable association<br />

keep<strong>in</strong>g C. apera <strong>in</strong> comb<strong>in</strong>ation with Callithrix jacchus (breed<strong>in</strong>g) was ma<strong>in</strong>ta<strong>in</strong>ed for 4-5<br />

years show<strong>in</strong>g very similar behavioural effects.<br />
