16.10.2018 EUCAW Speakers Hammerhead Shark research: Knowledge from the populations in the Canary Islands

HAMMERHEAD SHARK RESEARCH is a project that studies hammerhead sharks Sphyrna spp in the Canary Islands with the aim to contribute scientific base knowledge of these species in an understudied distribution. Information of hammerheads in this distribution is limited to the presence of two species (S. lewini and S. zygaena),…

15.10.2018 EUCAW Speakers The annual cycle of German adult Ospreys (Pandion haliaetus) – studies in the breeding and wintering areas as well as during migration since 1995 by means of satellite telemetry

During 1995 – 2011 we marked 28 adult Ospreys in NE-Germany with satellite tags working up to eight years. All except three males wintered in West Africa. The migratory paths followed while in Europe seemed much straighter and more directional compared to the migratory paths followed in Africa. This pattern was…

15.10.2018 EUCAW Speakers Year-round Satellite Tracking of Amur Falcon (Falco amurensis) reveals the longest migration of any raptor species across the open sea

The title for undertaking the most arduous of all raptor migrations, belongs certainly to the Amur Falcon, which is a complete transcontinental, transequatorial, long-distance flocking migrant. The principal breeding (mainly NE China) and wintering (mainly S. Africa) ranges are separated by both 70° of latitude and longitude. Details of the…
