Flocking in birds is associated with diet, foraging substrate, timing of activity, and life history
AbstractThe adaptive significance of flocking in birds has been long debated. In particular, the formation of flocks is thought to increase foraging...

Flocking in birds increases annual adult survival in a global analysis
Adaptive hypotheses for the evolution of group foraging in animals typically invoke enhanced foraging efficiency and reduced predation risk. Net...

Flock size increases with the diversity and abundance of local predators in an avian family
Group living has long been viewed as an adaptation to reduce predation risk. Earlier comparative analyses provided support for the hypothesis but...

Vision and vocal communication guide three-dimensional spatial coordination of zebra finches during wind-tunnel flights
Animal collective motion is a natural phenomenon readily observable in various taxa. Although theoretical models can predict the macroscopic pattern...

When flocking is costly: reduced cluster-flock density over long-duration flight in pigeons
Birds which fly in coordinated cluster-flocks can benefit through the formation of group-level structures and patterns which can deter predators by...

Collective motion: Influence of local behavioural interactions among individuals
Fascinating patterns are displayed in nature due to the collective coherent motion of many living organisms. The origin of collective behaviours is...

Flocking, Swirling and Spinning Stars in a Cell
Microtubuke (MT) filaments nucleated from centrosomes form star-like structures or asters. In eukaryotic cells, they act as the ‘railway network’ of...

Ungrazed seminatural habitats around farms benefit bird conservation without enhancing foodborne pathogen risks
ContextConservation in working landscapes is critical for halting biodiversity declines and ensuring farming system sustainability. However, concerns...

Novel form of collective movement by soil bacteria
Although migrations are essential for soil microorganisms to exploit scarce and heterogeneously distributed resources, bacterial mobility in soil...

A review of flocking behavior by Hook-billed Kite, Chondrohierax uncinatus, in South America
The Hook-billed Kite ( Chondrohierax uncinatus ) is a diurnal raptor species that is widely distributed across the Neotropics, but some aspects of its...

Effects of a regenerating matrix on the survival of birds in tropical forest fragments
BackgroundVast areas of lowland neotropical forest have regenerated after initially being cleared for agricultural purposes. The ecological value of...

Which birds participate in mass concentrations of Bramblings Fringilla montifringilla?—Ring recoveries, biometry, age and sex composition
The Brambling Fringilla montifringilla combines several special features of migration and wintering: differential migration according to age and sex...

The composition of mixed-species flocks of birds in and around Chitwan National Park, Nepal
BackgroundMixed-species flocks (MSFs) have been well sampled in the South Asia, but there has been as yet surprisingly little work on MSFs of Nepal,...

Aggregation pheromone interrupts death feigning in the red flour beetle Tribolium castaneum
Death feigning is a behavior in which a prey is rendered motionless due to stimulation or threat by a predator. This anti-predator defense mechanism...

The Loss (and Gain) of Defensive Adaptations in Island Plants and Animals: A Comparative Review
Compositional differences between islands and continents had marked consequences for the evolution of island life. Regardless of their taxonomic...

Not Forgetting…
Most penguins are social and like to do things in flocks, big or small. Indeed, being in flocks helps them avoid being eaten (Chap....

Biology and Ecology of the Redpoll (Acanthis flammea sensu lato, Passeriformes, Fringillidae) on Yamal Peninsula and in the Near-Ob Forested Tundra
AbstractThe features of the biology, ecology, and annual cycle of the Redpoll in the near-Ob forest–tundra and subarctic tundra of Yamal are...
