1. Neophobia and parental care in collared flycatchers (Ficedula albicollis)
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Parental care can be important especially in passerine birds and can depend on environment, food availability and behaviour. A behaviour that can affect the food supply for the offspring is neophobia, the fear of novel objects. The more fear the bird exhibits the less it visits the nest with food. READ MORE

2. The relative effect of gained extra-pair paternity versus ensured within-pair paternity on male fitness in collared flycatchers, Ficedula albicollis
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Variation in a male ability to gain extra-pair paternity and maintain within-pair paternity are important sources of variation in male fitness in socially monogamous species and thus become the resource of sexual selection on male secondary sexual traits. While the maximum possible number of offspring sired within the social pair-bond is limited by the female’s clutch size, the possible number of sired extra-pair young could in theory by much higher.

3. The limits of species recognition: heterospecific song learning in pied flycatchers
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : The closely related species pied flycatcher (Ficedula hypoleuca) and collared flycatcher (F. albicollis) co-occur on the Swedish island of Öland, where they compete over similar resources. The majority of male pied flycatchers have been found to incorporate elements of the collared flycatcher song in their repertoire. READ MORE

4. Malaria infected male collared flycatchers, Ficedula albicollis experience higher reproductive success and tend to have larger sexual ornaments
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : How parasites influence the population dynamics of their hosts depends on 1) theproportion of individuals that carry the infection in the population, 2) what type of individuals aremost susceptible to infection and 3) the fitness effects of infection. In this study I first investigate thefrequency of malaria strains transmitted in the African winter quarters or at the European breedinggrounds in collared flycatchers (Ficedula albicollis).

5. Life-History Divergence and Relative Fitness of Nestling Ficedula Flycatcher Hybrids
University essay from Zooekologi; Institutionen för biologisk grundutbildningAbstract : The typical intermediate morphology of hybrids may result in their failure to utilize the same niches as their parents. However, the fitness consequences of the potentially intermediate life-history traits of hybrids have been given less scientific attention. READ MORE
