Water birds need specific environments, but may use new areas. Double-crested cormorants are now nesting in the South-East of USA, including on small reservoirs, not only in the Great Lake system....

Common cuckoos are found in Eurasia, from Europe to Korea. All over the continent, they migrate to Africa, while they parasite different birds’ nests. Tracking them using Argos helps understand the...

Eurasian Woodcocks are birds which migrate across Europe. Their studies have long been led using rings, but the advent of small-enough satellite telemetry emitters now enables to follow them all...

Some bird species like the black-tailed godwits are nesting on ground, in grasslands. However, across all of lowland Europe, such areas have been transformed for intensive agriculture. Tracking by...

Harpy Eagles are threatened birds of prey of Central and South Americas. A study show why and how releases of rehabilitated or captive-born animals should consider home range characteristics and...

Tracking animals help in understanding their behaviour, which can benefit to their protection, even for abundant species such as the common woodpigeons. Their behavioral plasticity, demonstrated by...

The Hudsonian godwit is a migratory bird travelling a marathon, transoceanic flight from South America to Arctic or sub-Arctic North America. Their flight paths tracked using Argos, in relation with...

Protecting critically endangered species aims to better assess where and when the main threats to these species occurs. Using satellite telemetry technology, Philippine eagles were tracked to define...

Migratory birds, especially those which depend on coastal wetland habitats, are among the threatened animals. Identifying the key sites in their life cycle, including the stopovers used during...

Uncovering how young animals learn to move efficiently and find food, is one of the many possible uses of satellite telemetry. Here, researchers from British Antarctic Survey satellite-tracked...

One of the mysteries of migrant animals is their ability to find their way back and forth during their long-range travels. Several hypothesis were tested on Egyptian geese to try to understand their...

Red kites are medium-sized partially migratory raptor. They often winter in Spain, but their behaviour there and during those non-breeding periods have not been extensively studied using satellite...

Tracking a European shorebird called the Black-tailed godwit (Limosa l. limosa) has previously revealed that different populations of godwits have different migratory behaviours (see Black-tailed...

The Great Knot is an endangered shorebird and a long-distance migrant. Its activity was found to be mainly along the coast and was suspected to have few stopovers; while juveniles were recorded...

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...

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...

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...

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...

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...

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....

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...

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...

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....

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...

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...

The Amazon Rainforest is hard to reach, but home to a large number of species. Birds like the Amazonian black skimmers live apart of their life there, but move around a lot. Argos satellite...

Considering the suitability of the environment is the key to successfully reintroduce a species in an habitat where it disappeared. Oriental white stork disappeared from Japan fifty years ago. The...

Migratory birds may keep the same routes and the same nesting and wintering sites from year to year. Such species may be all the more fragile if environmental changes occur. Argos satellite...

Some species can be mostly unknown even nowadays. Beck’s petrel, a seabird living around Papua-New Guinea island is among them. Understanding where they breed, live can enable to protect them. Argos...

Migratory birds from a given species are frequently observed to follow the same routes, and do so every year. Tracking different populations with Argos satellite telemetry shows a very different...
