The Motus Wildlife Tracking System and the eBird database are two important resources for bird migration research. Motus utilizes a network of over 900 stations tracking at least 225 species on four continents to gather detailed data on bird movements. On the other hand, eBird is a citizen science project that encourages bird watchers to submit observations, providing valuable data for scientists to study bird behaviors. Both databases serve as centralized platforms for data sharing and collaboration among researchers, facilitating a better understanding of migration patterns.
