Abstract The function of nonvocal sounds in avian communication has rarely been investigated. I used playback of natural and digitally altered wing sounds from both sexes of Calliope Hummingbird (Stellula calliope) and Rufous Hummingbird (Selasphorus rufus) to test whether these stimuli altered their behavior. Stimuli played from behind target birds at artificial feeders were used to study responses that characterized the level of threat associated with each wing-sound stimulus. I classified… Expand
Wing, tail, and vocal contributions to the complex acoustic signals of courting Calliope hummingbirds
Multi-component signals contain multiple signal parts expressed in the same physical modality. One way to identify individual components is if they are produced by different physical mechanisms.Expand
Complex coevolution of wing, tail, and vocal sounds of courting male bee hummingbirds
TLDR
A negative phylogenetic correlation between presence of wing trills and singing is found, and it is hypothesized this transference occurs because wing trill and vocal songs serve similar functions and are thus redundant. Expand
The Displays and Sonations of the Black-Chinned Hummingbird (Trochilidae: Archilochus alexandri)
TLDR
It is shown that the display sounds of the male Black-chinned Hummingbird are sonations produced by feathers, and the timing of the trilled sounds during both the shuttle and dive displays corresponded to the wingbeat kinematics, which suggests that they are produced by the wings. Expand
Sounds of Modified Flight Feathers Reliably Signal Danger in a Pigeon
TLDR
The results indicate, nearly 150 years after Darwin's book, that modified feathers can be used for non-vocal communication, and they reveal an intrinsically reliable alarm signal. Expand
Flights of fear: a mechanical wing whistle sounds the alarm in a flocking bird
TLDR
This is the first demonstration that flight noise can send information about alarm, and it is suggested that take-off noise could provide a cue of alarm in many flocking species, with feather modification evolving specifically to signal alarm in some. Expand
Kinematic control of male Allen's hummingbird wing trill over a range of flight speeds
TLDR
The sexually selected 9 kHz wing trill of male Allen's hummingbirds is substantially louder in maneuvers than in rectilinear flight, and appears to be produced in supination, providing partial support for the wing rotation hypothesis. Expand
How Hummingbirds Hum: Oscillating Aerodynamic Forces Explain Timbre of the Humming Sound
The source of the hummingbirds distinctive hum is not well understood, but there are clues to its origin in the acoustic nearfield and farfield. To unravel this mystery, we recorded the acousticExpand
Hummingbird feather sounds are produced by aeroelastic flutter, not vortex-induced vibration
TLDR
Investigating the underlying mechanics of flutter and sound production of a series of different feathers in a wind tunnel indicates that flutter is not simply a vortex-induced vibration, and that the accompanying sounds are not vortex whistles. Expand
Specialized primary feathers produce tonal sounds during flight in rock pigeons (Columba livia)
TLDR
The outermost primary feathers (P10) in male and female rock pigeons (Columba livia) are specialized to produce tonalSounds during high-speed take-off at the expense of aerodynamic performance, revealing that production of tonal sounds incurs an aerodynamic cost. Expand

TLDR
An alternative, or complimentary, hypothesis is presented that synchronization of group movements may improve hearing perception and reduce auditory masking through periods of relative silence and facilitate auditory grouping processes. Expand

CHARACTERISTICS OF THE WING SOUNDS OF FOUR HUMMINGBIRD SPECIES THAT BREED IN CANADA
TLDR
The first description of a characteristic behavior, which is called the ‘Cobra’, in which an individual dramatically increases its wing-beat frequency is provided, and it is shown that female Black-chinned Hummingbirds (Archilochus alexandri) also produce wing trill components despite previous beliefs that these were unique to male hummingbirds. Expand
REPRODUCTIVE BEHAVIOR AND COMMUNICATION IN BLUE-THROATED HUMMINGBIRDS
TLDR
Behaviors that differed from many other hummingbirds that have been studied included strong reliance on vocal signals, lack of male aerial displays, and female advertisement of sexual readiness and may be linked to reduced sexual dichromatism and related to the species' preference for wooded riparian habitats. Expand
Roles of the wing whistle in the territorial behaviour of male broad-tailed hummingbirds (Selasphorus platycercus)
TLDR
Results of this study suggest that the wing whistle of male broad-tailed hummingbirds is important in maintenance of courting territories and hence in reproductive success. Expand
Organization of agonistic vocalizations in Black-chinned Hummingbirds
TLDR
The agonistic vocalizations of Black-chinned Hummingbird demonstrate a level of vocal complexity comparable to songs of many passeriues, but may reflect certain un- derlying constraints on the organization of avian vocalizations. Expand

Interspecific attraction to the mobbing calls of black-capped chickadees (Parus atricapillus)
TLDR
That significantly more birds approached the speaker and displayed mobbing behavior during the mobbing call playback suggests that black-capped chickadee mobbing vocalizations carry meaning for at least ten other avian species. Expand

Discrimination of colors by the black-chinned hummingbird,Archilochus alexandri
TLDR
Following experience with red at all feeders, the birds showed a modest tendency to visit red (620 nm, 650 nm) and blue (490 nm) rather than intermediate greens and yellows, which provides a more rigorous demonstration of color vision in hummingbirds than has heretofore been available. Expand
