Pied Flycatcher (Ficedula hypoleuca) Science Article 9 abstract I compared two populations of Pied Flycatchers Ficedula hypoleuca breeding in a coniferous forest with adverse weather conditions (‘marginal habitat’) and in a deciduous forest with a more favourable climate (‘good habitat’). Female mass was significantly larger during the reproductive cycle in the ‘good habitat’. The incubation […]

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 […]

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 […]
