The value of a mouthful: Flight initiation distance as an opportunity cost [PDF]
Flight initiation distance of animals when approached by a potential predator reflects the risk that an individual is willing to take when the individual has to gauge the value of staying put relative to the cost of flight.

(1) The aliasing of radial velocities from weather radars is a known challenge in meteorology. It may also occur during bird migration if the unambiguous velocity threshold is below the birds’ ground speed.

Evaluating UAM–Wildlife Collision Prevention Efficacy with Fast-Time Simulations
Urban Air Mobility (UAM) promises to reduce ground traffic and journey times by using electric vertical take-off and landing (eVTOL) aircraft for short, low-altitude flights, especially in urban environments.

Neotropical Bird Migration During The Ice Ages: Orientation And Ecology [PDF]
Reconstruction of breeding habitat of North American Neotropical migrants 18,000 years ago and 9,000 years ago indicated major shifts in both location and composition of plant communities relative to present conditions.

Reciprocal relationships in collective flights of homing pigeons [PDF]
Collective motion of bird flocks can be explained via the hypothesis of many wrongs, and/or, a structured leadership mechanism. In pigeons, previous studies have shown that there is a well-defined hierarchical structure and certain specific individuals ...

Foraging strategies of breeding seabirds studied by bird-borne data loggers [PDF]
Our research group has devised and manufactured a data logger, which, glued on the back of a bird, can detect and memorise the direction in which the bird is heading during a flight.

Patterns of nocturnal bird migration in southern Mexico
The Isthmus of Tehuantepec is the narrowest landmass between the Gulf of Mexico and the Pacific Ocean. It is known as an important stopover site and migration corridor for Nearctic-Neotropical migratory birds.We characterized nocturnal bird migration ...
