The American Robin is abundant, widespread, and often easily observable, making it an ideal animal for scientific investigations. Despite being the focus of many studies, much remains to be learned about this species. Priorities for future research include:
1. Lifetime reproductive success and population regulation, especially differences among geographic regions and habitat types, and between human-dominated and natural landscapes.
2. The role of anthropogenic change in robin ecology and behavior, including further investigations of artificial light and anthropogenic sound, as well as predation and mating in human-altered habitats.
3. Physiology and hormonal regulation of behavior.
4. Post-breeding dispersal and behavior of juveniles.
5. Territory establishment and spatial variation in the degree of territoriality.
6. Differences in migratory and non-migratory populations and the factors leading to these differences.
7. Disease ecology and the role of robins as reservoirs for infectious diseases such as West Nile virus.
8. Vocalizations and geographic differences in songs and calls.
