“…Females are monomorphic and are orange-rufous in color. Males and females share parental responsibilities such as nest construction, incubation, and feeding of nestlings (Mulder and Ramiarison 2003;Mizuta 2005). One pair raises one brood per breeding season.…”

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]

“…These terrestrial vertebrates show complex interspecific interaction networks that include predator-prey relationships and resource competition both within and between these classes (Mizuta 2002(Mizuta , 2005bMori & Randriamahazo 2002a;Nakamura 2004;Nakamura et al 2004;Hasegawa et al 2009). One common lizard in this community is the Madagascan spiny-tailed iguana, Oplurus cuvieri cuvieri.…”

Prey animals can reduce their risk of predation by detecting potential predators before encounters occur. Some animals gain information about nearby predators by eavesdropping on heterospecific alarm calls. Despite having well-developed ears, most lizards do not use vocal information for intraspecific communication, and few studies have shown practical use of the ears in wild lizards. Here, we show that the Madagascan spiny-tailed iguana (Oplurus cuvieri cuvieri ) obtains auditory signals for predator detection. The Madagascan spiny-tailed iguana and the Madagascar paradise flycatcher (Terpsiphone mutata) are syntopic inhabitants of the Ampijoroa dry deciduous forest of Madagascar. The iguana and the flycatcher have neither a predator -prey relationship nor resource competition, but they have shared predators such as raptors and snakes. Using playback experiments, we demonstrated that the iguana discriminates mobbing alarm calls of the flycatcher from its songs and then enhances its vigilance behaviour. Our results demonstrate the occurrence of an asymmetrical ecological relationship between the Madagascan spinytailed iguana and the paradise flycatcher through eavesdropping on information about the presence of predators. This implies that indirect interspecific interactions through information recognition may be more common than generally thought in an animal community.

“…We opted to include 0 scores because at least one of the parents should have had an opportunity to observe our activity near the nest prior to the simulated predation event during a provisioning bout or as a result of antipredator vigilance (Woodard & Murphy ). Antipredator vigilance is an important component of parental investment, and nest defense in particular (Woodard & Murphy ; Mizuta ), and presence near the nest is necessary to detect predators.…”

Do Birds Alter Levels of Parental Investment Based on Nest‐Site Habitat Features?

Many habitats have undergone rapid changes over the past century as a result of anthropogenic activities. Organisms can respond to changes in their environment in many ways, including how much they invest in a given reproductive bout. Optimality theory and life history theory together have provided a framework for understanding how individuals make decisions about the risks and rewards of investing high levels of resources into their offspring within the context of current vs. future reproduction. Shrubland birds in the United States often breed in habitat that has been impacted by humans to varying degrees and provide an ideal system for examining whether organisms alter their levels of parental investment based on the habitat around the nest site. In this study, we assessed levels of nest‐defense behavior during a simulated nest predation event in four shrubland birds: American robins (Turdus migratorius), gray catbirds (Dumetella carolinensis), brown thrashers (Toxostoma rufum), and northern cardinals (Cardinalis cardinalis). We found that thrashers and catbirds exhibited significantly higher levels of nest defense compared to robins and cardinals and that birds with larger broods acted more aggressively in defending them. We also found that thrashers acted less aggressively as the proportion of shrubland around the nest increased and as the proportion of developed land around the nest decreased and that cardinals acted less aggressively as the proportion of developed land around the nest increased. These patterns suggest that nest‐defense behavior can covary with features of the landscape surrounding the nest, but that the factors shaping that behavior can differ by species.
