Development and validation of a drill attachment for faster and safer deployments of fin-mounted geolocators in large-bodied sharks
Fin-mounted geolocators are widely used in marine studies to track animal movements and to design informed management strategies. However, the...

Multi-sensor geolocators unveil global and local movements in an Alpine-breeding long-distance migrant
BackgroundTo understand the ecology of long-distance migrant bird species, it is necessary to study their full annual cycle, including migratory...

Revealing different migration strategies in a Baltic Common Tern (Sterna hirundo) population with light-level geolocators
The Common Tern ( Sterna hirundo ) is one of Germany’s farthest migrating bird species. Ringing studies have shown the use of the East Atlantic flyway,...

Tracking Cuban Martin (Progne cryptoleuca) migration to wintering location and back using geolocators: solving a mystery
The Cuban Martin ( Progne cryptoleuca ) is an aerial insectivorous bird that breeds only in Cuba. It can be widely observed on the Cuban archipelago...

Non-breeding distribution, activity patterns and moulting areas of Sooty Albatrosses (Phoebetria fusca) inferred from geolocators, satellite trackers and biochemical markers
Sooty Albatrosses ( Phoebetria fusca ; Endangered) are biennially breeding birds with successful breeders typically spending at least 15 months at-sea...

Timing of migration and African non-breeding grounds of geolocator-tracked European Pied Flycatchers: a multi-population assessment
Using light-level geolocators, eight European Pied Flycatchers ( Ficedula hypoleuca ) from two breeding sites in Czechia were tracked. We also gathered...

Geolocator tagging of east Siberian Bluethroats
The Bluethroat subspecies Cyanecula svecica svecia occurs throughout the northern Palearctic. European C. s. svecia has been shown to follow a route...

Consequences of migratory distance, habitat distribution and season on the migratory process in a short distance migratory shorebird population
BackgroundThe migratory process in birds consists of alternating periods of flight and fueling. Individuals of some populations make few flights and...
-
Synchronous timing of return to breeding sites in a long-distance migratory seabird with ocean-scale variation in migration schedules
BackgroundMigratory birds generally have tightly scheduled annual cycles, in which delays can have carry-over effects on the timing of later events,...

No detectable effect of light-level geolocators on the behaviour and fitness of a long-distance migratory seabird
Light-level geolocators are increasingly popular devices for tracking migratory birds. However, to ensure that data on migratory behaviour represent...

A review of electronic devices for tracking small and medium migratory shorebirds
Small- to medium-sized shorebirds (< 200 g) can be particularly difficult to track with electronic devices due to their small size and long-distance...

Migration and non-breeding ecology of the Yellow-breasted Chat Icteria virens
Detailed information spanning the full annual cycle is lacking for most songbird populations. We examined breeding, migration, and non-breeding sites...
-
A synthesis of recent tools and perspectives in migratory connectivity studies
Migration movements connect breeding and non-breeding bird populations over the year. Such links, referred to as migratory connectivity, have...

Using light-level geolocations to monitor incubation behaviour of a cavity-nesting bird Apus apus pekinensis
The Bei**g Swift ( Apus apus pekinensis ) is a typical cavity-nesting bird that often nests inside holes and crevices in old architectures. Direct...
-
Population specific annual cycles and migration strategies in a leap-frog migrant
AbstractA common migratory pattern in birds is that northerly breeding populations migrate to more southerly non-breeding sites compared to southerly...

A 30,000-km journey by Apus apus pekinensis tracks arid lands between northern China and south-western Africa
BackgroundAs a widely distributed and aerial migratory bird, the Common Swift ( Apus apus ) flies over a wide geographic range in Eurasia and Africa...

Migration ecology of western gray catbirds
BackgroundFor many songbirds in North America, we lack movement details about the full annual cycle, notably outside the breeding season....

Daily foraging activity of an imperiled ground squirrel: effects of hibernation, thermal environment, body condition, and conspecific density
AbstractFood acquisition is among the most important tasks faced by free-ranging animals. Predation and thermal risks, however, can make foraging a...

Inter and intra-population variability of the migratory behaviour of a short-distance partial migrant, the Eurasian Stone-curlew Burhinus oedicnemus (Charadriiformes, Burhinidae)
Migratory behaviour in birds shows a remarkable variability at species, population and individual levels. Short-distance migrants often adopt a...

Pair bonds during the annual cycle of a long-distance migrant, the Arctic Tern (Sterna paradisaea)
BackgroundThe extent to which pairs remain together during the annual cycle is a key question in the behavioural ecology of migratory birds. While a...
