Wintering of Ospreys in Argentina: Insights from new records between 1993-2008

The migratory subspecies of the "American" Osprey (Pandion haliaetus carolinensis) breeds across most of North America. Most of these Ospreys winter north of the equator, although significant numbers travel farther south, reaching Argentina. The number of Osprey sightings in Argentina has...
