Ganusevich 2004 <p>Four female Peregrine Falcons <i>Falco peregrinus</i> breeding on the Kola Peninsula, Russia, were fitted with satellite-received transmitters in 1994. Their breeding home ranges averaged 1175 (sd&nbsp;=&nbsp;±714)&nbsp;km², and overlapped considerably. All left their breeding grounds in September and migrated generally south-west along the Baltic Sea. The mean travel rate for three falcons was 190&nbsp;km/day. Two Falcons wintered on the coasts of France and in southern Spain, which were, respectively, 2909 and 4262&nbsp;km from their breeding sites. Data on migration routes suggested that Falcons took a near-direct route to the wintering areas. No prolonged stopovers were apparent. The 90% minimum convex polygon winter range of a bird that migrated to Spain encompassed 213&nbsp;km² (<i>n</i>&nbsp;=&nbsp;54). The area of the 50% minimum convex polygon was 21.5&nbsp;km² (<i>n</i>&nbsp;=&nbsp;29). Data from this study agree with others from North America that show that Falcons breeding in a single area do not necessarily follow the same migratory path southward and do not necessarily use the same wintering grounds.</p> application/pdf 10.1046/j.1474-919X.2004.00253.x en Wiley Autumn migration and wintering areas of Peregrine Falcons Falco peregrinus nesting on the Kola Peninsula, northern Russia article
