Buildings promote higher incubation temperatures and reduce nest attentiveness in a Neotropical thrush
(Wiley-Blackwell, 2020-07-09)
Incubation is an energetically costly parental task of breeding birds. Incubating parents respond to environmental variation and nest-site features to adjust the balance between the time spent incubating (i.e. nest ...
Nesting biology of tapaculos (Rhinocryptidae) in fragmented south-temperate rainforests of Chile
(American Ornithologist Society, 2002)
We studied the effect of forest fragmentation on the nesting biology and reproductive success of three species of tapaculos (Rhinocryptidae) in relation to forest size, edge effects, and disturbance from livestock or logging ...
Cavity characteristics, but not habitat, influence nest survival of cavity-nesting birds along a gradient of human impact in the subtropical Atlantic Forest
(Elsevier, 2015-04)
Cavity-nesting vertebrates are an important component of biodiversity in tropical and subtropical forests, but their persistence will increasingly depend on remnant trees in logged forest and agricultural areas. To identify ...
Extreme use of feathers for nest construction by the Chilean Swallow (Tachycineta leucopyga) in the sub-Antarctic forests of southern Chile
(SOC Brasileira Ornitología, 2016-06)
Nesting birds commonly incorporate feathers into nest linings given their insulation properties. Although use of feathers is common among swallows, here we provide the first recording of nests built almost completely with ...
Lack of effect of microhabitat charaacteristics on nest predation and brood parasitims in creamy-bellied thruss (Turdus Amaurochalinus)
(Neotropical Ornithological Society, 2013-11)
Nest predation and brood parasitism are key factors affecting nest survival in passerine birds. As a result, birds may select nest sites that minimize the probability of nests being found by predators or by brood parasites. ...
Interpopulation variation in nest architecture in a secondary cavity-nesting bird suggests site-specific strategies to cope with heat loss and humidity
(American Ornithological Society, 2017)
© 2017 American Ornithological Society. Nest morphology can affect the breeding success of birds. Thus, birds inhabiting different environments may experience divergent selection for nest structure and composition that ...
Strong selection on mandible and nest features in a carpenter bee that nests in two sympatric host plants
(John Wiley and Sons Ltd, 2014)
Host plants are used by herbivorous insects as feeding or nesting resources. In wood-boring insects, host plants features may impose selective forces leading to phenotypic differentiation on traits related to nest construction. ...
Multifemale nests and social behavior in Euglossa melanotricha (Hymenoptera,Apidae, Euglossini)
(PENSOFT PUBLISHERSSOFIA, 2012)
The nesting biology and social behavior of the euglossine bee species Euglossa melanotricha was analyzed based on the monitoring of eight nests found in man-made cavities and transferred to observation boxes. Euglossa ...
Integrative approach on the diversity of nesting behaviour in fishes
(2022-05-01)
Nests are the key elements of the reproductive repertoire of several fish species. Understanding the physiological aspects behind their nesting behaviour is imperative to improve our knowledge about behavioural mechanisms ...
