Individual learning is a way that animals use to adaptively adjust their behaviour to conditions taking advantage of previous experiences. However, individual learning includes risks and costs that can be overcome by learning from others. Thus, several social and gregarious species, across many taxa, rely on social learning. Despite its relevance, the ability to learn from observation of others behaviour was tested in only a few species of birds. It is particularly interesting to test this capability in granivorous gregarious species, because they likely follow environmental cues to forage. We conducted a series of tests on social learning in a foraging task with a small cardueline finch, the Serin (Serinus serinus). We used an observer-demonstrator paradigm where observers were given the opportunity to learn to reach hidden food from observation of demonstrators that were previously trained to perform the task. Almost half of the birds tested were capable of learning (40%) from a conspecific in a colour-food association experiment, and learners were able to remember the association after fifteen days. Also, almost half of the birds tested for this revealed to be capable of reversal learning. The ability to learn was not influenced by sex or age, of both demonstrators and learners. However, learners had longer wings than non-learners. Perhaps, individuals proficient in social learning have a foraging efficiency advantage so that they can invest more energy in feather growth. We wondered what could explain the ability of learning by some but not all. Thus, we tested the birds for personality differences. Although we found repeatable personality traits using the novel object and mirror personality tests, they did not explain the differences in learning ability.
