In addition to their song, songbirds also have an extensive repertoire of calls. While the species-specific song must be learned as a young bird, most calls are, as in the case of all other birds, innate. Researchers have now discovered that in zebra finches the song control system in the brain is also active during simple communication calls. This relationship between unlearned calls and an area of the brain responsible for learned vocalizations is important for understanding the evolution of song learning in songbirds.

Individual differences in moving activity in a novel environment are linked to individual differences in vulnerability to angling, according to an experimental study. The study used novel, long-term observations of individual behavior in groups and authentic angling trials to analyze if behaviors predict the vulnerability to fishing in brown trout reared in traditional and enriched hatchery rearing environments. Based on the results, it can be predicted that fishing modifies the heritable behavioral traits of fish by favoring cautious fish.
