Résumé :	Mississippi Kites (Ictinia mississippiensis) are trans-equatorial, long-distance migrants that breed in North America and overwinter in South America. Information about their migration routes and winter distribution in the Neotropics is mostly anecdotal. By compiling records of Mississippi Kites in South America from the literature and previously unpublished observations (1904-2010), we identified 96 locality records (a location where a flock or individual was recorded) and 146 independent records of flocks (observations of flocks irrespective of year, location, or time of year). Our locality records included 38 (39%) during southbound migration (1 September-30 November), 18 (19%) during northbound migration (15 February-30 April), 38 (39%) during austral summer (1 December-14 February), and two (3%) during austral winter (1 May-31 August). Most Mississippi Kites (84, 88%) were observed between the 11 degrees S and 32 degrees S latitudinal band in central South America. Of our independent records of flocks, 133 (92%) were observed between 11 degrees S and 32 degrees S, 12 (7%) between 11 degrees N and
