“…data] suggesting that the nest predation by common brown lemurs is not a rare incident in this region. Predation pressure on the nest of the Madagascar paradise flycatcher is very high [9,10]. As a result of this observation, it is supposed that the common brown lemur is one of the crucial nest predators for the birds breeding in the forests of this area.…”

“…Therefore, predation pressure does not appear to differ between the two sites. Nest predation occurs frequently in this species, and parents start another breeding attempt when nest predation has occurred (Mizuta 2000(Mizuta , 2002Mulder and Ramiarison 2003). Early breeding would be advantageous for the parents to acquire reproductive success within a season, since early breeders have sufficient time to conduct a re-nesting attempt even when the first attempt fails because of nest predation.…”

Within-population variation in the timing of breeding in the insectivorous Madagascar paradise flycatcher, Terpsiphone mutata (L., 1766), was investigated in a dry forest of northwestern Madagascar. The study area was divided into two sites (namely, A and B) based on the distance from the waterside. An examination was conducted to determine whether the date of egg laying varies between the two sites, and if it does vary, what are the environmental factors that affect the variation. The females started egg laying significantly earlier at site B than at site A. The two sites are located in a continuous forest; hence, photoperiod and precipitation would not differ between them. The number of insects was higher at site B than at site A. The difference in the temperature was not considered to be the cause of the variation in the date of egg laying. Age structure of the females was not likely to differ between the sites. Therefore, the variation in the date of egg laying is considered to be caused by the difference in food abundance that is associated with the relative distance from the waterside.Résumé : Cette étude examine la variation du calendrier de la reproduction à l'intérieur d'une population du tchitrec malgache, Terpsiphone mutata (L., 1766), un oiseau insectivore, dans une forêt sèche du nord-ouest de Madagascar. La ré-gion d'étude est divisée en deux sites (A et B) d'après la distance du bord de l'eau. Il s'agit de savoir si les dates de la ponte des oeufs varient d'un site à l'autre et, en cas de variation, de trouver les facteurs du milieu qui l'expliquent. Les femelles commencent à pondre significativement plus tôt au site B qu'au site A. Puisque les deux sites se trouvent dans une forêt continue, la photopériode et les précipitations ne diffèrent pas d'un site à l'autre. Le nombre d'insectes est plus important au site B qu'au site A. Les différences de température ne sont pas considérées comme la cause de la variation du calendrier de ponte. La structure en âge ne varie vraisemblablement pas entre les sites. En conséquence, la variation dans les dates de ponte des oeufs est, semble-t-il, causée par une différence d'abondance de nourriture reliée à la distance relative du bord de l'eau.[Traduit par la Rédaction]

“…If perching serves the function of vigilance and is an ''unshared investment'' (Lazarus and Inglis 1986) in parental duty, parents should not change the duration of that behavior in relation to brood size, because predation would occur regardless of brood size. The predation pressure is very high in the study population, with more than 80% of nests being predated before fledging (Mizuta 2000(Mizuta , 2002b. The common brown lemur Eulemur fulvus fulvus (Mizuta 2002c) and Frances' sparrowhawk Accipiter francesii (Mizuta, unpublished data) are observed to predate the nest of the Fig.…”

“…Pairs build an open, cup-shaped nest on a fork of a small tree in lower strata of the forest (nest height above the ground: mean±SE=108.84±7.54 cm, range =49-550 cm, n=94; Mizuta, unpublished data). Pairs raise one brood per breeding season, but if eggs or nestlings are predated, parents make another breeding attempt at another site within their home range (Mizuta 2000).…”

Parental care behavior in the monogamous, sexually dimorphic Madagascar paradise flycatcher: sex differences and the effect of brood size

Parental care behavior in the monogamous, sexually dimorphic Madagascar paradise flycatcher: sex differences and the effect of brood size Abstract I studied the parental care behavior of the Madagascar paradise flycatcher Terpsiphone mutata in northwestern Madagascar. I especially focused on feeding, brooding and vigilance behaviors. Feeding rate did not differ between males and females, but females spent more time at the nest than males. Females dedicated their time to brooding, while males perched on the nest and were vigilant. Both parents changed the feeding rate in relation to brood size, so the feeding rate per nestling was not different among nests of different brood size. Duration of brooding by females increased with decreasing brood size, suggesting that the Royama effect, the pattern of lower feeding rate per nestling in larger broods, did not apply in this study. Males spent more time on vigilance than females. Anti-predator vigilance by males should be important for nestling survival given the high predation pressure typical of this population. In conclusion, males provide considerable parental care probably to minimize nestling starvation and to avoid nest predation. My results are not consistent with the general pattern of less parental effort by males in monogamous, sexually dimorphic species.
