“…Under both conditions, the fewer the number of other birds present, the more distress calls the bird(s) gave. This closely replicates our previous research (Gaioni et al, 1977(Gaioni et al, , 1980. The advantage of the companion-bird technique is that it allows the measurement of distress calling in individual ducklings.…”

“…These results were verified by an analysis of variance computed on the data from trials when 0-5 companions were present. Significant effects were found for number of companions remaining [F(5, (Gaioni et al, 1980) involving a procedure in which ducklings were exposed as a large group to a single imprinting stimulus. Those studies also revealed that a single imprinting stimulus was equivalent to several ducklings in terms of its effectiveness in suppressing distress calls.…”

“…Very little attention has been focused on sibling attachments (Shapiro, 1980). We have begun examining sibling interactions within the context of duckling perception of brood size (Gaioni, DePaulo, & Hoffman, 1980;Gaioni, Hoffman, Klein, & DePaulo, 1977). Ducklings reared in a brood of a given size adapt to that size such that they will give distress vocalizations if the number of birds in the brood is reduced substantially.…”

Peking ducklings were reared for 1-2weeks with either 9 or 12 companions, which were either conspecifics or imprinting stimuli (blocks of foam rubber). They were then tested for their tendency to distress call as the number of companions was reduced systematically. Consistent with prior research, ducklings reared with conspecifics modulated their distress calling as a function of both the number of companions with which they were reared and the number of companions with which they were tested. In contrast, ducklings reared with moving imprinting stimuli gave few if any distress calls, regardless of the number of stimuli with which they were reared or tested, as long as at least one imprinting stimulus was present. The difference in responding did not reflect just a lack of attachment to the imprinting stimuli, since when all stimuli were removed these ducklings gave as many distress calls as the ducklings that had all their conspecifics removed. Finally, ducklings reared with stationary imprinting stimuli displayed an erratic pattern of distress calling when the number of test stimuli was manipulated. These latter ducklings appeared to be less strongly imprinted than the ducklings reared with either conspecifics or moving imprinting stimuli. Implications for understanding duckling perception of brood size and the nature of sibling vs. filial imprinting are examined. Lorenz's (1935) pioneering work on the development of social attachments in young birds (imprinting) marked the beginning of an extensive research effort that continues to the present time. This research has focused largely on filial and sexual imprinting, that is, the processes by which a young bird learns the features of its mother and the species with which it will subsequently mate, respectively (

“…This "peer imprinting" effect may explain why, in the field, the mallard hen must make multiple forays from the nest to eventually entice the brood to follow her (Miller & Gottlieb, 1978). Gaioni, DePaulo, and Hoffman (1980) have suggested that group-reared hatchlings trained to an imprinting object may become imprinted to that object, but that evidence of the imprinting may be masked by competing responsiveness directed toward siblings. The absence of a visual preference for the familiar mallard hen over the unfamiliar pintail in Experiment I1 is not consistent with that view.…”

Training ducklings in broods interferes with maternal imprinting

Under natural conditions, if maternal imprinting is to occur it must occur in a social situation which includes the presence of broodmates. In the laboratory it has been shown that social rearing with siblings prior to maternal imprinting interferes with the establishment of maternal imprinting, whereas social experience with siblings after maternal imprinting enhances the imprinting experience. The present study examined the influence of social experience with broodmates during an imprinting trial on the establishment of a visually imprinted maternal preference in domestic mallard ducklings (Anas platyrhynchos). Twenty-four-hour-old ducklings were allowed to follow a stuffed mallard hen for 30 min either individually or in a brood of four same-aged ducklings. The birds trained alone subsequently showed an imprinted preference for the familiar mallard hen over an unfamiliar pintail hen or four stuffed ducklings in simultaneous choice tests at 48 and 72 hr after hatching. Ducklings trained with broodmates did not show a preference for the familiar mallard hen over the unfamiliar pintail hen and displayed a preference for the stuffed ducklings over the mallard hen at 48 and 72 hr choice tests. These results demonstrate that even brief (30 min) experience with siblings during a maternal imprinting trial results in peer imprinting that interferes with the establishment of maternal imprinting. These and other results of a similar sort render dubious the significance of most laboratory studies of imprinting for an understanding of such events in nature.

“…It has been suggested that “[m]ost mammalian young cry when separated from their mothers and homes” (Carden, Barr, & Hofer, 1991, p. 17). Investigators have documented separation calls from a variety of animal young, including ducks (Gaioni, DePaulo, & Hoffman, 1980), chickens (Rajecki, Eichenbaum, & Heilweil, 1973), guinea pigs (Pettijohn, 1979), dogs (Gurski, Davis, & Scott, 1980), and human (Michelsson, Christensson, Rothgänger, & Winberg, 1996) and nonhuman (Newman, 1985) primates.…”

In the current revival of interest in the emotional and mental lives of animals, many investigators have focused attention on mammalian infants that emit distress vocalizations when separated from the home environment. Perhaps the most intensively studied distress vocalization is the ultrasonic vocalization of infant rats. Since its discovery, this vocalization has been interpreted both as a communicatory signal for the elicitation of maternal retrieval and as the manifestation of emotional distress. In contrast, the authors examined the cardiovascular causes and consequences of the vocalization, and on the basis of this work, they hypothesized that the vocalization is the acoustic by-product of the abdominal compression reaction (ACR), a maneuver that results in increased venous return to the heart. Therefore, the vocalization may be analogous to a sneeze, serving a physiological function while incidentally producing sound.
