Effects ofProtocalliphoraParasites on Nestling Food Composition in Corsican Blue TitsParus caeruleus: Consequences for Nestling Performance

Habitat and Annual Variation in Arthropod Abundance Affects Blue TitCyanistes caeruleusReproduction

“…It has been shown in many studies that the abundance of caterpillars does influence tit laying time and breeding success (Perrins 1965, van Balen 1973. In general, the abundance of caterpillars in our study habitats is high in comparison with many other areas (Bańbura et al 1994, Thomas et al 2001, Bańbura et al 2004. Blondel et al (2006) suggested that the abundance of caterpillars has a direct effect on Corsican Blue Tit reproduction up to the threshold value of 0.5 g/m 2 /day of frassfall.…”

Effect of Old Nest Material on Nest Site Selection and Breeding Parameters in Secondary Hole Nesters — a Review

“…It should also be remembered that the negative effect of ectoparasites may be compensated by adult birds, for example, by increasing parental expenditures (e.g. Bouslama et al 2002, Bańbura et al 2004.…”

“…It was found that adult birds compensate ectoparasite pressure by increasing the number of their trips with food for nestlings (e.g. Bouslama et al 2002, Bańbura et al 2004, which can also reveal nests to predators, as well as expose adult birds to predators (e.g. Lima & Dill 1990, Martin et al 2000.…”

Patterns of year-to-year variation in haemoglobin and glucose concentrations in the blood of nestling Pied Flycatchers Ficedula hypoleuca

“…Thus, some parents cannot invest enough resources to raise offspring of high physiological quality (Sibly and Calow 1986). Nestlings that are in better condition have the chance to more effectively deal with various hazards, such as periods of food shortage, disease or parasitic infestation (Ots et al 1998;Bańbura et al 2004). Studies have shown that some blood parameters provide useful indicators of the body condition and state of health of animals, including birds (Atwal et al 1964;Bradley and Threlfall 1974), when collected and interpreted with appropriate caution (Fair et al 2007;Lill 2011;Lill et al 2013).…”
