Qualitative descriptive information on both vocal and visual displays of waterfowl is abundant (e.g., Heinroth 1910, 1911; Lorenz 1953; Weidmann 1956; Johnsgard 1965; McKinney 1965a, 1969, 1970), and quantitative data are available for visual displays of a few species of ducks (e.g., Weidmann 1958; Weidmann and Daily 1971; Simmons and Weidmann 1973; Johnsgard 1960; McKinney 1961, 1965b; Dane et al. 1959; Dane and van der Kloot 1964; Field 1970). But quantitative data on vocal displays of adult… Expand
A ctivity patterns , vocalizations , and site selection in nesting Blue winged T eal
  • 2012
The Blue-winged Teal A nas discors breeds throughout the prairie pothole region of North America. Considerable data are available on its breeding biology (Bennet 1938: Sowls 1955; Glover 1956; DaneExpand
Maternal vocalizations of mallard ducks (Anas platyrhynchos)
TLDR
The exodus call differs from the pre-exodus call in having more notes per burst and more harmonics, with a corresponding upward shift in dominant frequency. Expand
Biology and Conservation of the Laysan Duck (Anas laysanensis)
-A two-summer, mark-recapture study of Laysan Ducks (Anus laysanensis) resulted in a population estimate of 5 10 birds with over 90% of the birds marked. Individuals seemed long-lived with the lowExpand
Vocal recognition of a nest-predator in black grouse
TLDR
Black grouse recognized raven calls and were alerted, displaying typical neck stretching, followed by head scanning, and eventual escape, and surprisingly, males tended to react faster and exhibited a longer duration of vigilance behavior compared to females. Expand
Acoustic Differences between the Scoters Melanitta nigra nigra and m. n. americana
TLDR
Scoter vocalizations may have a role in pair formation and pair bonding and support recent proposals to treat M. n. Expand
Distress call alternation in peking ducklings (Anas platyrhynchos)
Abstract Peking ducklings ( Anas platyrhynchos ) were found to alternate their distress calls with those of conspecifics. This alternation response consisted of two components: a strong tendency toExpand
Acoustical comparison between decrescendo calls of female mallards and mimicry by humans using artificial duck calls
TLDR
This study compared acoustic features of field recordings of the decrescendo calls of wild female mallards with those of duck callers and found that cocobolo, osage orange, pecan, acrylic, and bocote calls with double reeds produced notes acoustically most similar to female mallarddecrescendos. Expand
Spacing and Three-bird Flights of mallards breeding in pothole habitat
TLDR
Wild mallards (Anas platyrhynchos) were observed in pothole habitat near Minnedosa, Manitoba and territorial behaviour was most pronounced during a brief period from just prior to laying until early incubation. Expand
The Functions of Female Calls in Birds
Abstract Birds’ vocalizations commonly are categorized in two types: songs and calls. Yet, the study of avian vocalizations is male-biased and most of research to date has focused on male song. EvenExpand
Analysis of mallard’s (Anas platyrhynchos) behavior depending on phenology period and the size of the flock on water basins in Szczecin
TLDR
The results show that the most active period for Mallard's Anas platyrhynchos are the autumn and winter months (pairing period), while more aggressive behaviours can be observed when the population density is high. Expand

A Preliminary Analysis of the Decrescendo Call in Female Mallards (Anas Pla Tyrhynchos L.)
TLDR
The conditions necessary for the elicitation of this call were studied in captive, paired female Mallards, Anas platyrhynchos, in both outdoor and indoor pens andaired females gave significantly more calls when visually isolated from their mates than when their mates were present. Expand
A Quantitative Study of Sexual Behavior of Mallards and Black Ducks
TLDR
The results of this general study indicate that the Black Duck is much more closely related to the Mallard than is generally supposed and that the two forms should probably be considered to be only subspecifically distinct. Expand
An Analysis of the Display of the Goldeneye Duck (b uCephala Clang Ula (L.))
TLDR
A quantitative analysis of the sexual display of the Goldeneye duck revealed that individuals are more stereotyped in the performance of their actions than the population, and that individuals can sometimes be classed as "fast" or "slow" in their performance. Expand
Three-bird flights in the Mallard
TLDR
In North Kent, three-bird flights performed during the nesting season are not territorial in the Mallard or the Shoveler, and behaviour of paired drakes during Mallard flights indicates a polygamous tendency. Expand
THE CHARACTERISTICS AND CONTEXT OF IMPRINTING
  • P. Bateson
  • Biology, Medicine
  • Biological reviews of the Cambridge Philosophical Society

TLDR
The primary object of this article is to reconsider the characteristics of imprinting and the ways in which they have been interpreted. Expand
Observations on the incidence of following of visual and auditory stimuli in naive mallard ducklings (Anas platyrhynchos).
TLDR
It is suggested that the departure of mallard ducklings from the nest often takes place at an age well past the critical period, and under these circumstances the long persistence of a high level of responsiveness to stimuli releasing the following reaction must have a high adaptive value, particularly in connection with the dangerous journey of the brood from the Nest to the nearerst water.

The Social Aspects of Reproductive Behavior in the Pintail
TLDR
This study examines the reproductive cycle of the Pintail with particular emphasis on the motivation and function of aerial activity which can be observed throughout the nesting season. Expand
Electrical Stimulation of Agonistic Behavior in the Mallard
Electrical stimulation of the brain of unanesthetized, freely moving adult Mallard ducks (Anas platyrhynchos) produced response patterns characteristic of the aggressive and escape behaviors of thisExpand
Observations on sound production in the Anatidae
A comparison of inter-species variations in the tracheal anatomy and acoustical characteristics of anatid vocalizations supports the contention that the trachea serves as a resonating tube, thusExpand
The comfort movements of Anatidae.
TLDR
Almost all comfort movements are of universal occurrence in basic situations in the family; the few specific variations represent adaptations to different ways of life, and are of very limited use as indicators of taxonomic relationships. Expand
