Abstract
BARREIRO-PADILLA, Manuela; TORRES, Wilmar Alexander; MONTOYA-LERMA, James and CRUZ-BERNATE, Lorena. ¿Do behavioral, body and habitat features influence the cognitive performance of Sicalis flaveola?. Bol. Cient. Mus. Hist. Nat. Univ. Caldas [online]. 2022, vol.26, n.2, pp.123-141. Epub Nov 22, 2022. ISSN 0123-3068. https://doi.org/10.17151/bccm.2022.26.2.6.
In recent decades, the demonstration of cognitive abilities in birds has been documented and various tests have been designed to adequately evaluate their capacities. However, the results of these tests can also be influenced by aspects other than cognitive ability, such as behavioral, body and habitat characteristics. Species facing rapid and new environmental changes must express a cognitive performance that allows them to overcome obstacles through learning and acting, despite the fear of novelty. Even though Sicalis flaveola is extremely successful in disturbed environments, as with most tropical species, its behavioral flexibility and learning capacity are largely unknown. The objective of this study was to evaluate the cognitive ability of S. flaveola and to determine whether cognition is affected by shyness, neophobia and body condition in individuals from two populations with different degrees of urbanization in Colombia. Obstacle removal and color discrimination tests were applied to 28 individuals in captivity. Shyness and neophobia were not found to be influenced by the place of origin, body condition or sex. For obstacle removal test, shyness and neophobia affected S. flaveola learning speed of learning, but not discrimination. The ability to discriminate was in turn affected by the speed at which the birds learned to remove obstacles, level of difficulty, and the number of attempts required to solve the test. Learning capacity in this species is confirmed.
