ABSTRACT
Sex determination in monomorphic birds is a precondition for captive breeding programs and management and conservation strategies for threatened species. Most species of the order Psittaciformes often present complications since these birds lack external sexual phenotypic traits, making it impossible to differentiate males and females. In the present study, we used molecular techniques to determine the sex of 31 individuals belonging to nine species of the order Psittaciformes kept under human care at the Akumal Monkey Sanctuary & Rescued Animals in Quintana Roo, Mexico. This is a useful and low-cost methodology based on the analysis of the conserved region of the CHD1 gene, which was amplified by PCR with two sets of primers P8/P2 and 2550F/2718 R. All individuals were successfully sexed with the first set of primers, while only 28 out of 31 samples (90%) could be amplified with the second set. Out of the 31 individuals analyzed, fifteen are female, and seventeen are male. This information represents a handy tool for adequately managing birds under human care, resulting in their reproduction and eventual reintegration into their natural habitat.
