Nest Architecture, Clutch Size, Nestling Growth Patterns and Nestling Attendance of the Fire-eyed Diucon (Xolmis pyrope) in North-Central Chile
(Wilson Ornithological Soc, 2016)
We present descriptions of nest architecture, clutch size, nestling growth and nestling attendance for the Fire-eyed Diucon (Xolmis pyrope), based on nests found at the Fray Jorge National Park, Chile, at the northernmost ...
Attack on Chestnut-bellied Euphonia nestlings by army ants
I report some observations of a Chestnut-bellied Euphonia (Euphonia pectoralis) nest in a lowland Atlantic Forest of southeastern Brazil during the early nestling period. During 7.5 hours of observations, the nest was ...
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 ...

Parental risk-taking behaviour and nest defence during the nestling rearing stage in Northern House Wrens Troglodytes aedon
(Museum and Institute of Zoology, Polish Academy of Sciences, 2013-03)
Risk-taking behaviour of short lived nesting birds is often explained in relation to the reproductive value of offspring (the reproductive value hypothesis) and the harm that the absence of parental care can cause to ...
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 ...
Coproparasitological study of European starling nestlings (Sturnus vulgaris) in Argentina
(Tubitak Scientific & Technical Research Council Turkey, 2016-03)
We examined 71 fecal samples of European starling nestlings from Buenos Aires Province, Argentina, in the reproductive seasons of 2012 and 2013 to detect the presence of intestinal parasites and determine their prevalence. ...

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 ...
