I will discuss the interpretation of the most recent measurements of the extensive air-showers produced by UHECRs at the Pierre Auger Observatory, and outline current strategies aiming to answer the question of UHECR origin. Emphasis will be given to studies of UHECR arrival directions, dedicated searches for neutral particles (neutrons, photons and neutrinos), and the nascent program of real-time searches for transient UHE emission, as part of multi-messenger monitoring networks.
