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.

＜正＞ MacNeilage, Studdert-Kennedy and Lindblom （1991） postulated that handedness evolved in primates through selective pressures that favoured lateral bias for postural support and feeding. Accordingly, primates evolved a left hand specialisation for visually guided food reaching and right hand specialisation for postural support.

Objective: To report the case of an infertile female patient with cystic fibrosis who was diagnosed with endocervical metaplasia of the endometrium at diagnostic hysteroscopy and successfully treated with an oral estroprogestinic formulation. Design: Case report. Setting: University hospital. Patient(s): A 27- year- old infertile female patient with cystic fibrosis. Intervention(s): Hysteroscopy with multiple random biopsies was performed at the time of the first visit and after a 10- month cycle with an oral estroprogestinic formulation. Main Outcome Measure(s): Hysteroscopic evaluation with target biopsy; histological examinations of endometrial specimens. Result(s): Our patient benefited from a 10- month cycle with an oral estroprogestinic formulation. At the control visit we noticed a significant improvement in the hysteroscopic appearance of her endometrium, and the histological examination confirmed the complete reversion of the metaplastic alterations previously observed. Conclusion(s): The present report suggests a novel histological alteration possibly involved in affecting fertility in women with cystic fibrosis. In addition, the positive response to the estroprogestinic treatment observed in our patient poses new questions regarding the relationship between ovarian hormones and cystic fibrosis transmembrane conductance regulator protein regulation, offering interesting perspectives for a hormonal therapy in the treatment of subfertility in women with cystic fibrosis.
