Combining radio-telemetry and radar measurements to test optimal foraging in an aerial insectivore bird

This study uses radar and biotelemetry to show Little Swifts adjust foraging behavior based on insect abundance, with reduced flight distance and increased colony visits on high-prey days.

Soaring migrants flexibly respond to sea-breeze in a migratory bottleneck: using first derivatives to identify behavioural adjustments over time

This study analyzes how soaring birds adjust their flight behavior in response to sea-breeze patterns using radar data and statistical modeling.

Groping in the fog: soaring migrants exhibit wider scatter in flight directions and respond differently to wind under low visibility conditions

The paper studies how soaring birds adjust their flight behavior in fog, finding increased directional scatter and altered wind responses compared to clear conditions.

Causes and consequences of facultative sea crossing in a soaring migrant

This study examines how atmospheric and geographic factors influence route selection in migrating white storks, finding that wind patterns and energy costs affect whether birds cross or circumvent the Mediterranean Sea.
