“…However, differences between intraspecific and interspecific imprinting experience could be of great importance. Differences in the experimental design could perhaps also account for the different results between SCHUTZ (1965) and the present study.…”

Significance of Mother and Sibling Experience for Mating Preferences in the Mallard (Anas platyrhynchos)

Social attachment seems necessary for sexual imprinting. In mallards the likely period of social attachment is from hatching until the broods disperse. The potential imprinting objects are mother and siblings. Four combinations of mother‐sibling groups of same and different colour were used (N = 131). The groups were kept together from hatching until the young were 12 weeks old. When sexually mature, the birds' choices of mate were recorded. Colouration is an important cue in mate selection. Both mother and siblings are of importance. The effect of experimental factors cannot be attributed to any particular sex.

“…Is it dependent on a more or less closed program (MAYR 1974;SCHUTZ 1965;KLINT 1975)? Since there are no differences between 8 8 and 99 (in Table 1) and the pair formation process can be either male or female dominated, this point will not be considered in this paper.…”

“…SCHUTZ , 1975KLINT 1975;WALTER 1973). SCHUTZ (1965) suggests that female ducks recognize male conspecifics through a genetic mechanism. Such a mechanism seems plausible when the high inter-specific variability in plumage coloration of male ducks is considered.…”

A Model of Imprinting Evolved from Neurophysiological Concepts

The imprinting process is described by a model evolved from physiological data. For the case of sexual imprinting in zebra finches a second sensitive phase, occurring at sexual maturity, is considered. The first sensitive phase is not restricted exclusively to the imprinting of sexual objects. Properties of the model allow for the explanation of apparent reversibility of imprinting. The same physiological mechanisms involved in the organization of simple neuronal connections are assumed to operate in the highly complex networks associated with imprinting phenomena.

“…Thus, each brood included an 'experimental' male reared with heterospecific females and a 'control' male reared with females of his own species. It was not possible to form larger broods or rear ducklings with adult females owing to logistical constraints, but previous work has demonstrated that interaction with siblings contributes to both filial (Lickliter & Gottlieb 1986) and sexual (Schuetz 1965;Cheng et al 1978) imprinting in Anas ducklings. Broods were reared in visual isolation in outdoor enclosures with ad libitum access to food, water and shelter.…”

Sexual imprinting misguides species recognition in a facultative interspecific brood parasite

Sexual reproduction relies on the recognition of conspecifics for breeding. Most experiments in birds have implicated a critical role for early social learning in directing subsequent courtship behaviours and mating decisions. This classical view of avian sexual imprinting is challenged, however, by studies of megapodes and obligate brood parasites, species in which reliable recognition is achieved despite the lack of early experience with conspecifics. By rearing males with either conspecific or heterospecific brood mates, we experimentally tested the effect of early social experience on the association preferences and courtship behaviours of two sympatrically breeding ducks. We predicted that redheads (Aythya americana), which are facultative interspecific brood parasites, would show a diminished effect of early social environment on subsequent courtship preferences when compared with their host and congener, the canvasback (Aythya valisineria). Contrary to expectations, cross-fostered males of both species courted heterospecific females and preferred them in spatial association tests, whereas control males courted and associated with conspecific females. These results imply that ontogenetic constraints on species recognition may be a general impediment to the initial evolution of interspecific brood parasitism in birds. Under more natural conditions, a variety of mechanisms may mitigate or counteract the effects of early imprinting for redheads reared in canvasback broods.
