“…An alternative explanation of our result is the reporting of a false positive effect of nest size due to the presence of a Type I error. Although the first possibility cannot be completely ruled out, the second seems more plausible, especially when only one (Antonov ) of nine previous studies (Møller , Lent , Hatchwell et al . , Palomino et al .…”

“…The nest‐size hypothesis proposes a positive relationship between nest size and the probability of predation, larger nests being more conspicuous and thus subject to higher predation (Snow ). As support for this hypothesis is scarce in observational studies (Antonov , but see Møller , Lent , Palomino et al . ), and equivocal in experimental studies (Slagsvold , Møller , Weidinger , Biancucci & Martin ), it seems reasonable to assume that the effect of nest size may often be masked by parental activity or other factors.…”

Experimental enlargement of nest size does not increase risk of predation or brood parasitism in the Great Reed Warbler Acrocephalus arundinaceus

We assessed whether nest size affects the probability of nest loss using dyads of large and small (large being twice the size of small) inactive Great Reed Warbler Acrocephalus arundinaceus nests placed at similar sites in Great Reed Warbler territories. Large nests were not predated significantly more frequently than small nests. Experimentally enlarged active Great Reed Warbler nests suffered non‐significantly higher predation compared with non‐manipulated control nests. Our experiments did not support the nest‐size hypothesis and suggested that nest size does not appear to be a factor affecting the risk of nest predation in this species. The probability of brood parasitism by the Common Cuckoo Cuculus canorus was also unaffected by experimental nest enlargement, supporting the commonly accepted hypothesis that the Common Cuckoo searches for suitable host nests by host activity during nest building rather than nest size.

Nests are structures built to support and protect eggs and/or offspring from predators, parasites, and adverse weather conditions. Nests are mainly constructed prior to egg laying, meaning that parent birds must make decisions about nest site choice and nest building behavior before the start of egg-laying. Parent birds should be selected to choose nest sites and to build optimally sized nests, yet our current understanding of clutch size-nest size relationships is limited to small-scale studies performed over short time periods. Here, we quantified the relationship between clutch size and nest size, using an exhaustive database of 116 slope estimates based on 17,472 nests of 21 species of hole and non-hole-nesting birds. There was a significant, positive relationship between clutch size and the base area of the nest box or the nest, and this relationship did not differ significantly between open nesting and hole-nesting species. The slope of the relationship showed significant intraspecific and interspecific heterogeneity among four species of secondary hole-nesting species, but also among all 116 slope estimates. The estimated relationship between clutch size and nest box base area in study sites with more than a single size of nest box was not significantly different from the relationship using studies with only a single size of nest box. The slope of the relationship between clutch size and nest base area in different species of birds was significantly negatively related to minimum base area, and less so to maximum base area in a given study. These findings are consistent with the hypothesis that bird species have a general reaction norm reflecting the relationship between nest size and clutch size. Further, they suggest that scientists may influence the clutch size decisions of hole-nesting birds through the provisioning of nest boxes of varying sizes.

“…There is some evidence that nest predation increases with nest size in open-nesting small and medium-sized birds (Møller, 1990;Sásvari et al, 1995;Herranz et al, 2004;López-Iborra et al, 2004;Biancucci and Martin, 2010). In Olivaceous Warblers (Hippolais pallida), non-predated nests are significantly smaller and denser than predated nests (Antonov, 2004). Thus, nest predation may limit nest size and correspondingly canalise effort into constructing denser rather than bulkier nests.…”

Avian Nests and Nest-Building as Signals

Birds may signal their condition, health or parental disposition to mates through large nests or intense or elaborate nest-building. The mass, number or elaborateness of nests may exceed their strict reproductive requirements. In several species, courtship rituals include exhibition of nesting materials to mates, and some nests are not used for breeding. Signalling through nests or nest construction may occur both before and after mating and may involve either males or females. Only males appear to be involved in pre-mating signalling, while both males and females may signal after mating. In several species, nest size and nest building activity has been associated with the condition of nest-building males, and females in some cases, while the evidence for parental disposition has been more mixed. Nest defence capacity has also been associated with nest size. In some species, males attract more mates through construction of multiple nests not related to breeding. The benefits obtained by males after pairing through differential allocation of their mates have been found in several species in terms of larger clutches, earlier hatching, biased sex ratios and increased parental investment. There is less evidence of this type of benefits for females. Measured responses of assumed receivers of the information provided by active nest construction may positively affect their fitness. Predators are probably attracted to bulky nests and so nest predation may have selected for concealed nests and for inconspicuous nest building activities, which has probably limited exaggeration of nest-building signals. There is also some evidence that ectoparasites and brood parasites may be attracted to bulky nests. Although signalling through nest construction appears as a plausible evolutionary scenario, much more empirical work needs to be done to demonstrate the relevance of nest-building signals.
