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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

Reportamos un caso de apropiación interespecífica de nido en donde una Torcaza (Zenaida auriculata) usurpa el nido de un Zorzal Chalchalero (Turdus amaurochalinus). Ambos pichones, incluido un pichón parásito de cría, ...

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 ...
