Abstract
A population of Common Blackbirds Turdus merula was studied to investigate the relationships between the presence of blood parasites and host morphome trics, a putative sexually selected trait (bill colour), and reproductive p arameters. Haematozoa of four genera were detected and their prevalence was high. Infection was negatively associated with adult morphometrics: adults infected with Leucocytozoon were in relatively poor body condition and had shorter wings than uninfected birds. The bill colour of males infected wit h Plasmodium tended to be duller than that of uninfected males, and in fema les Haemoproteus infection was significantly positively associated with bil l coloration. Haematozoan infection of females was unrelated to measured re productive parameters, and there was no relationship between blood parasite infection and the provision of parental care.
