Understanding how animals respond to atmospheric conditions across space is critical for understanding the evolution of flight strategies and long-distance migrations. We studied the three-dimensional movements and energetics of great frigate birds (Fregata minor) and showed that they can stay aloft for months during transoceanic flights. To do this, birds track the edge of the doldrums to take advantage of favorable winds and strong convection. Locally, they use a roller-coaster flight…

Atmospheric conditions create freeways, detours and tailbacks for migrating birds
TLDR
In general, individual birds seem to have a much more flexible response to weather than previously thought, but there are also similarities in migratory behaviour across taxa.
Migrating ospreys use thermal uplift over the open sea
TLDR
Five juvenile ospreys equipped with GPS-Accelerometer–Magnetometer loggers were able to find and use thermal uplift while crossing the Mediterranean Sea, indicating that atmospheric convection occurred when surface waters were warmer than the overlaying air.
Do Seabirds Control Wind Drift during Their Migration across the Strait of Gibraltar? A Study Using Remote Tracking by Radar
This study presents data on the directional flying behaviour of the five most abundant seabird species migrating across the Strait of Gibraltar in relation to the wind, as observed from the north…
The Effects of Atmospheric Currents on the Migratory Behavior of Soaring Birds: A Review
Abstract Atmospheric currents influence the choice of migratory routes and flight characteristics of birds as well as their decisions regarding migration onset and stopovers. Among long distance…
Remotely sensed wind speed predicts soaring behaviour in a wide-ranging pelagic seabird
TLDR
It is shown that remotely sensed ocean wind speed and direction are highly significant predictors of soaring behaviour in a migratory pelagic seabird, the Manx shearwater, and thus indicates that shifts in wind patterns driven by climate change could impact this and other species.
An Instrumented Golden Eagle’s (Aquila chrysaetos) Long-Distance Flight Behavior
Simple Summary All large birds have devised ways to save on the costly energy demands of flight. Geese, which form into a precise V formation, are a familiar example. Current measurements from GPS…
Flight of frigatebirds inside clouds - energy gain, stability and control.
Match between soaring modes of black kites and the fine-scale distribution of updrafts
TLDR
It is shown that updraft maps produced from publically available data can be used to predict where soaring birds will concentrate their flight paths and how they will behave in flight, and is recommended to improve environmental impact assessments of new wind-energy installations.
How frigate birds soar around the doldrums
TLDR
On page 74 of this issue, Weimerskirch et al. show that great frigate birds (Fregata minor) reduce transit costs by riding strong thermal updrafts beneath or inside cumulus clouds and then gliding long distances to another thermal, searching for food along the way.

Flight performance: Frigatebirds ride high on thermals
TLDR
Data collected by altimeters and satellite transmitters attached to individual frigatebirds are used to show that these birds are continuously on the wing, day and night, putting frigatebird at an evolutionary extreme that enables them to exploit tropical waters in which prey is scarce.
MARINE METEOROLOGY. SOME RESULTS OF A TRADE CUMULUS CLOUD INVESTIGATION
Abstract : Cross sections through 2 trade cumulus clouds are presented which show the temperatures, turbulence, and water vapor content of the clouds and their environment, the cloud slope, and the…
The roller coaster flight strategy of bar-headed geese conserves energy during Himalayan migrations
TLDR
A “roller coaster” strategy, of tracking the underlying terrain and discarding large altitude gains only to recoup them later in the flight with occasional benefits from orographic lift, is shown to be energetically advantageous for flights over the Himalayas.
Extreme endurance flights by landbirds crossing the Pacific Ocean: ecological corridor rather than barrier?
TLDR
It is proposed that this transoceanic route of bar-tailed godwits may function as an ecological corridor rather than a barrier, providing a wind-assisted passage relatively free of pathogens and predators.
First evidence of a 200-day non-stop flight in a bird.
TLDR
The first unequivocal evidence is presented that an individual bird of the Alpine swift (Tachymarptis melba) can stay airborne for migration, foraging and roosting over a period of more than 6 months, implying that all vital physiological processes, including sleep, can be perpetuated during flight.
Global aerial flyways allow efficient travelling.
TLDR
It is suggested that birds, even if incapable of predicting wind individually, could adjust their migratory routes at a population level, and this may result in the emergence of low-cost flyways representing a global network of aerial migratory pathways.
Changes in Wind Pattern Alter Albatross Distribution and Life-History Traits
TLDR
Foraging range in wandering albatrosses has shifted poleward in conjunction with changes in wind pattern, while their rates of travel and flight speeds have increased, and the duration of foraging trips has decreased, breeding success has improved, and birds have increased in mass.

The Mechanics of Flight and Bird Migration Performance
TLDR
It is shown that flying animals travel relatively fast, and therefore — provided they can obtain sufficient food and water — have the opportunity to travel long distances in relatively short times, and against this background that avian migration has evolved.
