Triple brooding by the blackcap
Original language description
The blackcap Sylvia atricapilla is typically single-brooding species that frequently renests in C and N Europe. Previously, only six cases of doublebrooding but none of triple-brooding have been reported from observation of individually marked birds. I recorded triple-brooding in one blackcap female, whose breeding could be followed over three years owing to easily recognizable aberrant (unpigmented) eggs. The first two of three nesting attempts in one year were successful but the third nest was depredated in late incubation. The female returned and bred successfully the next year. The low frequency of multi-brooding in this species results more likely from time (frequent renesting because of heavy nest predation) than from physiological constraints.
