“…There are examples reported for birds (flamingos (Stevens 1991, Pickering et al 1992) and mammals (black lemurs, Eulemur macaco, and mongoose lemurs, Eulemur mongoz (Hearn et al 1996)). In Przewalski's horse, Equus przewalskii, white rhinoceros, Ceratotherium simum, and vicuna, Vicugna 6icugna, reproductive success increased in larger groups (Bareham 1973, Dolan 1977.…”

Legendre, S. 2001. Allee effect, sexual selection and demographic stochasticity. -Oikos 92: 27 -34.The negative frequency-dependent effect of reproductive success in animals on population growth refers to a category of phenomena termed the Allee effect. The mechanistic basis for this effect and hence an understanding of its consequences has been obscure. We suggest that sexual selection, in particular female mate preferences, is a previously neglected component giving rise to the Allee effect. Lack of breeding and reduced reproductive success of females at low population densities are commonly described in situations where females have little or no opportunity to choose a mate, consistent with this suggestion. We developed a demographic model that incorporated the effects of lack of female choice on rates of reproduction. Using either a mating system with incompatibility or a system with a directional mate preference, we show that commonly encountered levels of reproductive suppression in the absence of suitable mates in a population, where sexual selection still operates, may increase the effects of demographic stochasticity considerably.

“…Because studies at individual zoos don't allow for generalization across the population, multizoo studies are preferred here. Early multizoo research studies that considered multiple indicators contributed considerably to knowledge about flamingos (Pickering, Creighton, & Stevenswood, 1992) and black rhinoceros (Carlstead et al, 1999).…”

This project aimed to estimate a species' adaptations in nature and in captivity, assess welfare, suggest environmental changes, and find species characteristics that underlie welfare problems in nonhuman animals in the zoo. First, the current status of zoo animal welfare assessment was reviewed, and the behavioral ecology approach was outlined. In this approach, databases of species characteristics were developed using (a) literature of natural behavior and (b) captive behavior. Species characteristics were grouped in 8 functional behavioral ecological fitness-related categories: space, time, metabolic, safety, reproductive, comfort, social, and information adaptations. Assessments of the strength of behavioral adaptations in relation to environmental demands were made based on the results available from the literature. The databases with literature at the species level were coupled with databases of (c) behavioral observations and (d) welfare assessments under captive conditions. Observation and welfare assessment methods were adapted from the animal on the farm realm and applied to zoo species. It was expected that the comparison of the repertoire of behaviors in natural and captive environments would highlight welfare problems, provide solutions to welfare problems by environmental changes, and identify species characteristics underlying zoo animal welfare problems.

“…This study aimed at investigating the presence of differences in the parental behaviour of a pair of greater flamingo in the presence of an infertile and a fertile egg. First, species-specific parental behaviours, such as egg-care, comfort behaviour, nest-building and protection [2] [7] [8] [9] [10] were found in the first and in the second period in both the female and male flamingos, suggesting an overall good welfare and wilderness of the subjects [14]. Second, the behaviour of the female flamingo varied significantly between the two periods and this variability might occur based on egg fertility.…”

“…The infertile egg was laid on March, 6 th and removed from the nest on April, 4 th (after the usual flamingo incubation period expired), to encourage the pair to lay a new egg [2]. The second egg was laid on April, 17 th and hatched successfully on A single-case analysis was performed to compare data of each flamingo partner between the two periods [11] [12] and non-parametric statistic tests were used [13].…”

Fertility of captive flamingos varies between flocks, species and seasons. Individuating infertile eggs could be helpful to facilitate important decisions. Wild animals could be encouraged to abandon the nest or not, whereas in captivity removing non-viable egg would lead birds to lay a new one. The aim of this study was to investigate the parental behaviour of a pair of greater flamingos (Phoenicopterus roseus) in the presence of a fertile and an infertile egg. Data on the posture and behaviours of the pair on the nest were collected over two different periods: first period-an infertile egg was laid; second period-a fertile egg was laid. For each period, 28 ten-minute sessions per flamingo partner were run. Results revealed that female flamingo spent significantly more time standing on the nest in the first than in the second period (P = 0.010). Moreover, when standing on the nest, the female performed significantly more egg-care behaviour (attention to the egg, egg rotation/moving) in the first than in the second period (P = 0.010). No significant differences between periods emerged in the male flamingo posture on the nest and behaviours. Findings from this study suggest that female flamingos stand on the nest longer if the egg is infertile, paying more attention and examining it deeply. This study provides new insights into greater flamingo parent-embryo communication. Future research is needed to improve our knowledge on this topic, as well as on the husbandry of this species in the controlled environment.
