Interspecific eavesdropping on alarm calling has been considered evidence that species
participating in mixed-species groups benefit from reduced risk of predation. Few studies …

We assessed experimentally how the quality and quantity of social information affected
foraging decisions of starlings (Sturnus vulgaris) at different neighbour distances, and how …

Nonlethal predator effects arise when individuals of a prey species adjust their behaviour
due to the presence of predators. Non-lethal predator effects have been shown to affect …

▪ Abstract It has recently been argued that the paradox of helping behavior in birds has been
solved. This optimism may be premature. I argue that there is no obvious dichotomy …

A type of itinerant mixed-species foraging association of New Guinean birds, the brown and
black flock, is distinctive in that member species converge on two alternative colours rather …

In most bird species, parents raise offspring cooperatively. In some cases, this cooperation
extends to helpers‐at‐the‐nest who assist the breeders with a range of tasks. While …

Intraspecific flock-feeding occurs in many species of birds but the ecological factors that
promote the behavior are not clear. Adaptive hypotheses suggest that such flocking should …

Among the various species that form mixed‐species bird flocks,“nuclear species” are
thought to be important in flock formation and maintaining flock cohesion. Such nuclear …

Research on cooperative breeding has begun to focus on direct fitness benefits gained by
helpers, particularly when individuals are unrelated to those they assist. There has been …
