Full annual cycle tracking helps to explain differences in population trends of far eastern curlew
The far eastern curlew is a large shorebird, migrating between Australia and far-east Asia. Some of its populations are more endangered than others. Understanding why this might be is helped by...
Polar bears tracked for more than 30 years in the Beaufort Sea
Polar bear’s foraging success is dependent on the presence of sea ice. Arctic sea ice, however, is rapidly decreasing in extent and thickness, and summer open-water periods are lengthening. As...
Argos helps in detecting beluga whale feeding sounds
Argos can help in understanding an endangered species behavior, by providing with locations but also collecting other data measured by a wide range of possible sensors. Some populations of beluga...
Very young green turtles go into the Sargasso Sea
The life of young (“lost years”) marine turtles had long been a mystery. Improvements in satellite telemetry now enable to unveil part of it. North Atlantic young green turtles, in particular, seem...
Tracking blue-winged teals, an avian influenza host
Wild migratory waterfowl such as blue-winged teals are known host of avian influenza. They can contaminate poultry which in turn develop highly contagious poultry diseases, some rare times affecting...
Franciscana dolphins are staying close to home
Franciscana dolphins are small cetaceans living along the South American coast. They are threatened, in particular from anthropogenic activities, including fishing gear. Argos can help to better...
Chinese and Japanese sparrowhawks fly over the East-Asian continent
Chinese and Japanese sparrowhawks are migratory raptors from East Asia. They migrate from Russia and China to Indonesia and other islands nearby. Understanding their migration routes, stopover sites...
Adelie penguin movement analysed in three dimensions
Adelie penguins live and breed around Antarctica. As with all penguins, they forage in a three-dimensional environment, ranging horizontally at-sea and diving vertically to capture prey. A recent...
Constellation update: HEMERIA & Kinéis keep us informed
Kinéis, 25 nanosatellites carrying the metamorphosis of the Argos system is on its way. Our first Kinéis constellation update was earlier this year where we went backstage with Michel Sarthou,...
Tracking juvenile northern gannets: post-fledging movements and migration journeys
Juvenile northern gannets fledge independently from their parents. They are therefore required to learn flight and foraging skills and make an autumn migration on their own. Mortality in seabirds is...
Western Australian green turtle behaviour analysed
A large population of green turtles is found in Western Australia. Using a database of tracks enables scientists to model their behaviour and help in deciding the protection regulations to enforce....
Whimbrels crossing tropical storms
Whimbrels migrate at the peak of the hurricane season, crossing the Atlantic. Different populations of this American shorebirds have different strategies to deal with tropical storms. However, they...
A whale’s slumber detected in Argos data
Animal tracking with Argos began in the 1980s. Improved techniques and satellite coverage now allow for much more tracking, with better resolutions. However, old tracks analysed with current methods...
Argos Telemetry Collars Allow Scientists to Track Macaw Movement Patterns and Advocate for Expanded Protection
Macaws are living in the wild – they are not “only” pets. Tracking Scarlet and Blue-and-Yellow Macaw with Argos enables to demonstrate that they move between protected and non-protected areas....
Less oxygen in the ocean may mean more threats from fisheries for blue sharks
Blue sharks, as many pelagic species of sharks, are often found in the surface layers above the existing Oxygen Minimum Zones. Those layers might shrink due to climate change and the expansion of...
Light-bellied Brent geese migrate non-stop across the open-ocean
Wild geese are among the most famous migratory birds – stars of fiction and documentaries. However, there are a number of different species, the Light-bellied Brent Geese among them. They don’t have...

[WEBINAR] Argos Bird Telemetry: User Community Stopover
Registrations are now closed. This webinar was an opportunity to bring the community (virtually) back together while sharing some great research. Thank you to everyone who participated. You can...
Manatee tracking study highlights the problems of dams in Africa
Manatees can live in rivers. However, in Africa, dams have been built over rivers, so that mitigation and modifications should be made to let the manatees come and go with the wet and dry seasons. A...
Albatrosses detect illegal fishing boats
Albatrosses tend to be attracted by fishing boats, which is one of the main threats on the species. The bycatch risk is usually assessed by comparing albatrosses’ and (legal) boats locations....
Jaguars in need of increasing biosphere reserve
Jaguars are one of the emblematic animals throughout the Americas. As most large terrestrial predators, it is threatened of extinction. Tracking them using Argos satellite telemetry enable to better...
How do sea turtles fare after being rehabilitated and released?
Sea turtle rehabilitation centres are becoming increasingly important to threatened sea turtle populations around the world. However, one key question is whether rehabilitation is actually helpful...
Backstage pass: Kinéis constellation update
If you had to describe Argos in two words, what it would be? According to Michel Sarthou, Chief Technical Officer at Kinéis, former Head of Argos space segment at CNES (French Space Agency) it would...
Common nighthawk populations do not stay apart during migrations
The common nighthawk is an American migratory bird, traveling long distances between North America and Tropical South America. For their conservation and understanding, biologists study if their...
3 Top Tips for using your Goniometer with Thomas Gray
Thomas Gray joined the Argos team in 2016 and has quickly become our go-to person on all things Goniometer. He brings ten years of sales and marketing experience in the underwater tech realm...
Argos helps in revealing how juvenile emperor penguins learn to feed
Emperor penguins and their young are emblematic of Antarctica. Argos satellite telemetry enabled to track the adults quite early. Now the scientists are looking at how the juveniles are learning to...
Lost Glider at sea found thanks to Argos and Goniometer
Gliders are valuable platforms in terms of equipment but also in terms of the vital information they collect. It is therefore not surprising that many of them are equipped with small Argos beacons...
How male Antarctic fur seals compete with fisheries and penguins for krill
Krill is at the base of the food-chain near Antarctica. It is also fished, with regulations enforced in regions where endangered species are also feeding on it. However, other species can also...
