![]() The male begins the courtship display by opening his wings up and back, curving his head down in a hook shape.What does the Andean condor courtship display look like? ![]() Over the 10 years between 19, a pair of Andean condors in Cali, Colombia, laid eggs almost every month. In conditions where warm temperatures are recorded throughout the year, Andean condors do not appear to breed seasonally. Before that, both males and females were motionless for hours in their cages. ![]() Zoos in the northern hemisphere report condors breeding from midwinter to midsummer, which corresponds to January through July.Ī breeding pair at the San Diego Zoo, California, showed signs of interacting with one another only when the weather conditions warmed up. The initiation of breeding activity of Andean condors in zoos appears to be triggered by changes in temperature and day length. When far from the nesting period, the courtship displays are less elaborate but peak in frequency and intensity before egg fertilization and laying. However, this pair laid eggs in October (Cailly-Arnulphi, et al 2014).Īs with other large birds of prey, the Andean condor forms pairs, engage in courtship displays, and copulates throughout the year. In Argentina, a wild nesting pair initiated courtship displays in April and continued until October, when incubation started (Lambertucci y Mastruantoni 2008).Ī separate wild pair showed a courtship display followed by copulation in August. Pair formation begins months before the nesting period. The timing and behavior associated with pair formation can be determined using scattered field observations and observations of birds in zoos.
