Abstract
Abstract Autumn migration routes of two Dutch female Montagu’s Harriers (Circus pygargus) were documented for the first time using satellite telemetry. Both migrated to their African wintering area—one via the Straits of Gibraltar through the Mediterranean and the other via Italy/Tunisia. The rate of travel was comparable to values reported for larger raptor species.
Highlights
Satellite tracking has proven to be a useful technique to document migratory routes of large bird species, such as White Storks (Ciconia ciconia; Berthold et al 1992, 2004), Peregrine falcons (Falco peregrinus; Fuller et al 1998), Ospreys (Pandion haliaetus; Hake et al 2001; Alerstam et al 2006) and eagle species (Meyburg et al 1995, 2003)
The proportion of Harriers passing over Gibraltar is higher than that over Italy, but the reverse pattern is observed in spring
Hake et al (2001) reported that a female Osprey bred at her first autumn migration stop-over site in the following year
Summary
Satellite tracking has proven to be a useful technique to document migratory routes of large bird species, such as White Storks (Ciconia ciconia; Berthold et al 1992, 2004), Peregrine falcons (Falco peregrinus; Fuller et al 1998), Ospreys (Pandion haliaetus; Hake et al 2001; Alerstam et al 2006) and eagle species (Meyburg et al 1995, 2003). The proportion of Harriers passing over Gibraltar is higher than that over Italy, but the reverse pattern is observed in spring. In 2005, Montagu’s Harriers could for the first time be tracked using satellite transmitters.
