“…In agreement with Trivers, Emlen and Gring (1977) suggested disparate PI in monogamous birds, with females investing more than males. However, they neglected aspects of PI subsequently demonstrated to be of importance, such as defense of offspring (Andersson et aI., 1980;Curio, 1980;Regelmann and Curio, 1986;Breitwisch, 1988) and care of fledglings 0. Zaias and Breitwisch, 1988).…”

“…4.3.1. Brood Defense Regelmann and Curio (1986) noted the generality of the finding that male birds tend to defend their broods against predators more strongly than do females. It is clear that many instances of such defense include a risk to the parent bird.…”

“…Dring (1982) appears to be one of the few investigators who has recognized implications of this association (see also Shields, 1984;Regelmann and Curio, 1986). Where there is an advantage to long-term pair bonding, the health of the mate becomes important in influencing parenting patterns to favor the maintenance of a long-term pair bond.…”

“…Certainly one of the best-studied passerines, the Great Tit is known to display male-biased tertiary sex ratios (Orell and Ojanen, 1979;Curio and Regelmann, 1982;Regelmann and Curio, 1986). Adult female mortality is higher than male mortality in both the breeding and nonbreeding seasons (E. Curio, personal communication).…”

“…Moreover, barred warbler males have well-spaced barring on underparts, and recently new evidence has been collected that underpart barring in bird plumage may have warning functions and can help in effective deterrence of intruders (Welbergen and Davies 2011). Most authors demonstrated higher intensity of mobbing in nest defence in males than in females in various bird species (Regelmann and Curio 1986;Pavel and Bureš 2001;Klvaňová et al 2011;Kryštofková et al 2011). First, antipredatory response may be a part of self-advertisement and evidence of male quality (Hogstad 2005;Klvaňová et al 2011).…”

Comparison of nest defence behaviour between two associate passerines

Nest predation is one of the most important factors limiting reproductive success, and antipredator behaviour can significantly reduce the loss of avian broods. I carried out field experiments on two sympatric passerines: the barred warbler and the red-backed shrike. Many authors have described the protective nature of nesting association between these species. However, we have little knowledge about the true nature of the relationships between associates. I examined (1) whether barred warblers and redbacked shrikes respond differently to an avian predator, and (2) whether males and females differ in the intensity of nest defence. Decoys of a known nest predator and a nonpredatory control species were used to examine the types and relative intensity of parental response. I measured behavioural responsiveness by recording aggressive behaviour toward each model during the nestling period. Barred warblers and red-backed shrikes showed considerable variation in their response. Warblers more vigorously defended their own territories than shrikes. No differences between the sexes in antipredator behaviour in red-backed shrike were found. By contrast, in barred warbler, male was more involved in nest defence. The experimental tests provide evidence that these two species are able to differentiate between a predator and non-predator species.

Function of snake mobbing in spectral tarsiers

Numerous species are known for their tendency to approach and confront their predators as a group. This behavior is known as mobbing. Snakes seem to be one of the more consistent recipients of this type of predator-directed behavior. This paper explores individual differences (sex and age) in the mobbing behavior of the spectral tarsier toward live and model snakes. This study was conducted at Tangkoko Nature Reserve (Sulawesi, Indonesia) during 2003-2004. During this research, 11 natural mobbing events and 31 artificially induced mobbing events were observed. The mean number of individuals at a mobbing was 5.7. The duration of mobbing events was strongly correlated with the number of assembled mobbers. Adults were more likely than other age classes to participate in mobbings. Males were more likely than females to participate in mobbings. Mobbing groups often contained more than one adult male, despite the fact that no spectral tarsier group contains more than one adult male. No difference in body size between extragroup males and resident males was observed, refuting the "attract the mightier" hypothesis. The number of mobbers did not affect whether the tarsier or the snake retreated first, countering the "move-on" hypothesis. The "perception advertisement" hypothesis was tentatively supported, in that live snakes were rarely seen in the area following mobbing calls, in comparison to when tarsiers either ignored the snake or alarm call.
