Since the first studies in the mid-twentieth century, lightweight electronic tracking devices
have been increasingly used to study waterfowl movements. With half a century of …

Satellite‐based technologies that track individual animal movements enable the mapping of
their spatial and temporal patterns of occurrence. This is particularly useful in poorly studied …

The use of biologging technology has increased exponentially over the last decade,
allowing us to study animal behaviour at a level of detail not previously possible. It is clear …

Background Tracking devices have enabled researchers to study unique aspects of
behavior in birds. However, it has become clear that attaching these devices to birds often …

Identifying an organism's migratory strategies and routes has important implications for
conservation. For most species of European ducks, information on the general course of …

Food resources are assumed to limit waterfowl populations in the Mississippi Alluvial Valley,
thus bioenergetic models are used for spatial allocation of food resources to provide …

A paradox of avian long-distance migrations is that birds must greatly increase their body
mass prior to departure, yet this is presumed to substantially increase their energy cost of …

Birds in flight are proposed to adjust their body orientation (heading) and airspeed to wind
conditions adaptively according to time and energy constraints. Airspeeds in goal‐directed …

Background The timing of migration for herbivorous migratory birds is thought to coincide
with spring phenology as emerging vegetation supplies them with the resources to fuel …

Blue-winged teal (Anas discors) are abundant, small-bodied dabbling ducks that breed
throughout the prairies of the northcentral USA and central Canada and that winter in the …
