I några korta rapporter i denna tidskrift har hävdats att blandade kullar speciellt hos hålhäckande fåglar förekommer ofta och att sådana kullar ofta har rapporterats (Merilä 1994, Petrassi et al. 1998). I motsats till dessa åsikter påstår jag att företeelsen i själva verket är sällsynt, åtminstone vad gäller nordiska förhållanden.

Extra Pair Paternity

Female mass in most altricial birds reaches its maximum during breeding at egg-laying, which coincides temporally with the fertile phase when extra-pair paternity (EPP) is determined. Higher mass at laying may have two different effects on EPP intensity. On the one hand, it would lead to increased wing loading (body mass/wing area), which may impair flight efficiency and thereby reduce female’s capacity to resist unwanted extra-pair male approaches (sexual conflict hypothesis). On the other hand, it would enhance female condition, favouring her capacity to evade mate-guarding and to search for extra-pair mates (female choice hypothesis). In both cases, higher female mass at laying may lead to enhanced EPP. To test this prediction, we reduced nest building effort by adding a completely constructed nest in an experimental group of female pied flycatchers (Ficedula hypoleuca). Our treatment caused an increase in mass and thereby wing loading and this was translated into a significantly higher EPP in the manipulated group compared with the control group as expected. There was also a significant negative relationship between EPP and laying date and the extent of the white wing patch, an index of female dominance. More body reserves at laying mean not only a higher potential fecundity but a higher level of EPP as well. This interaction had not previously received due attention but should be considered in future studies of avian breeding strategies.

Ceratophyllus Gallinae

Numbers of ectoparasitic blow fly (Protocalliphora azurea) larvae (Diptera: Calliphoridae), adult and larval hen fleas, Ceratophyllus gallinae (Siphonaptera: Ceratophyllidae), and other nest-dwelling insects were counted from the nests of the great tit, Parus major, and the pied flycatcher, Ficedula hypoleuca, in southwestern Finland around a factory complex emitting large quantities of sulphuric oxides and heavy metals. Protocalliphora azurea larvae were more frequently found in the nests of P. major than in those of F. hypoleuca. The prevalence of P. azurea larvae tended to be lower in polluted areas. The number of P. azurea larvae correlated positively with nest size and brood size of P. major. This may be caused by difficulties in sanitation of large and crowded nests. The numbers of fleas and their larvae were negatively affected by moisture in the nests. Nests of F. hypoleuca contained more adult fleas in polluted areas. This may indicate reduced resistance of birds exposed to heavy metals, but other possibilities are also discussed. We found a detrimental effect of P. azurea larvae on the growth of P. major nestlings, and an effect of fleas on mortality of F. hypoleuca nestlings, but these effects were not enhanced by air pollution. We conclude that the ectoparasites studied, at densities observed in our study area, are of minor importance in determining the breeding success of these two bird species.
