Lethal and sublethal effects of botfly (Philornis seguyi) parasitism on House Wren nestlingsEfectos Letales y Subletales del Parasitismo de Philornis sobre los Pichones de Troglodytes aedon
(Cooper Ornithological Society, 2012-02)
We studied the effect of botfly (Philornis seguyi) parasitism on survival and growth of House Wren (Troglodytes aedon) nestlings. We investigated whether nestling survival was related to (1) the intensity of botfly ...
NESTLING BEHAVIOR and PARENTAL CARE of THE COMMON POTOO (NYCTIBIUS GRISEUS) IN SOUTHEASTERN BRAZIL
(Wilson Ornithological Soc, 2011-03-01)
We recorded and quantified the nocturnal activity and parental care of a brooding Common Potoo (Nyctibius griseus) using an infrared camera in southeastern Brazil. Parents alternated care of the nestling and decreased their ...

(Wilson Ornithological Soc, 2011-03-01)
We recorded and quantified the nocturnal activity and parental care of a brooding Common Potoo (Nyctibius griseus) using an infrared camera in southeastern Brazil. Parents alternated care of the nestling and decreased their ...
Parental body condition and high energy value of fish determine nestling success in Magellanic penguin (Spheniscus magellanicus)
(Springer, 2018-06)
Nestling growth and survival of marine birds are influenced by multiple factors. Oceanic conditions influence food availability and energy value of the diet and affect nestling condition. Climate variables, like heavy ...
Behavioral experiments in a wild passerine cause short-term reductions in parental provisioning and nestling mass
(Sociedad de Biología de Chile, 2009)
Non-mimetic shiny cowbird nestlings escape discrimination by baywings in absence of host nest mates
(Springer, 2019-09)
Nestlings of obligate brood parasites must obtain resources from heterospecific hosts that are attuned to the solicitation behaviours of their own progeny. Failing to match the appropriate stimuli may result in suboptimal ...
Sex-specific costs of rearing a nestling and its implications in the brood sex ratio of Magellanic penguins
(Springer, 2021-08)
In birds, possible explanations for a bias in brood sex ratio include differential cost of rearing nestlings of different sexes, and different parental fitness returns related to offspring sex. We studied brood sex ratio ...
Parental investment in eggs and its effect on nestling growth and survival in Magellanic Penguins
(Csiro Publishing, 2014)
Life-history variables evolve in response to cost-benefit trade-offs. For birds, larger eggs are thought to be beneficial for development of offspring but are energetically costly to produce. Further, egg-size dimorphism ...
Effect of natural brood size variability on growth and survival of thornbird nestlings
(Wiley Blackwell Publishing, Inc, 2016-09)
For many bird species, brood size is a highly variable trait. Several aspects of the development and survival of nestlings are affected by brood size. Most scientific evidence comes from brood manipulation experiments, and ...
