Parental care in Pied Flycatchers Ficedula hypoleuca: Energy expenditure in relation to plumage colour and mating status

Pied Flycatcher (Ficedula hypoleuca) Science Article 11 abstract Females may benefit from expending more resources in care of offspring sired by sexually attractive males than by those of unattractive males in species with biparental care. Attractive males may therefore reduce their share of parental expenditure to increase own survivorship and to further mating success. On […]

Egg burial in penduline tits, Remiz pendulinusr.its role in mate desertion and femalepolyandry

Penduline-Tit (Remiz pendulinus) Science Article 1 abstract One important component in the mating strategy of an already-mated individual is the decision to remain with the partner and care for the offspring or to desert. Almost all research on nest desertion has focused on the costs and benefits of continued parental care versus desertion of both […]

The influence of nest size on heat loss of Penduline Tit eggs

Penduline-Tit (Remiz pendulinus) Science Article 2 abstract The size and quality of nest influence mate choice and parental behaviour in several birds. Previousworks in Penduline Tits showed that females prefer to mate with males that build largenests, and females desert small nests whereas they incubate eggs in large nests. We testedwhether female preference may be […]

Ecological relationships between feather mites (Acari) and wild birds ofEmberizidae (Aves) in a fragment of Atlantic Forest in northeastern Brazil

Palm Tanager (Thraupis palmarum) Science Article 1 abstract The objective of this study was to investigate feather mites on birds of the Family Emberizidae, tocollect data on the ecological ectoparasite-host relationship and infestation level. A sum of 94 birds of 9 specieswas captured at the Refugio Ecologico Charles Darwin, Igarassu, Pernambuco, Brazil, from August 1996 […]

SUGAR-TASTING ABILITY AND FRUIT SELECTION IN TROPICAL FRUIT-EATING BIRDS

Palm Tanager (Thraupis palmarum) Science Article 2 abstract The sugar-tasting abilities of four species of tanagers and two species of manakins were tested. Three tanager species were able to detect differences in diets containing 8%, 10%, and 12% sugar. In pairwise choice trials, they preferred the diet highest in sugar. Neither species of manakin discriminated […]
