In the French West Indies, five turtle species are threatened. This includes the hawksbill turtle, green turtle, leatherback turtle, loggerhead turtle and olive Ridley turtle. Three of these species are tracked closely by national and local authorities.

 

Protecting wildlife with Argos

The Argos system is one of the prinicipal technologies used by scientists and conservationists, to identify feeding and nesting areas, and to better understand the turtles’ migratory patterns. Each month, close to 650 turtles are tracked by Argos worldwide. The data collected via the Argos system are crucial to developing conservation strategies and also help with public awareness campaigns, demonstrating to the public how vulnerable these protected species are.

 

Better understanding migration

Damien Chevallier, scientist at the CNRS-IPHC, reveals a migratory journey of more than 20,000 km undertaken by a leatherback turtle. This turtle left Martinique in June 2018 to arrive in Senegalese waters (close to Cape Verde) in January 2019. Its six month journey alternated between feeding and travelling.

The most recent site visited by this turtle, just north of Cape Verde is known for intensive fishing. Accidental bycatch by fishing vessels is one of the major threats to turtles today. In French Guiana, special measures (i.e. Turtle Exclusion Devices -TED) are being used and other techniques to limit accidental bycatch of marine turtles during fishing campaigns are being explored. Results of this tracking study suggest that similar measures should perhaps be adapted along the threatened turtles’ entire migration route.

A journey of more than 20,000 kilometers was undertaken by this leatherback turtle. It left Maritinique in June 2018. Its latest positions, off the coast of Senegal, were reported in January 2019. Turtle tracked by Damien Chevallier, CNRS-IPHC. Click for map.

15.10.2018 Animal tracking applications 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…

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…
