During the 25 seasons (1974-1998), the breeding success of Collared Doves was determined by tracing the fates of 7882 nests found in S3upsk, Northern Poland. The kind of losses recognized were: complete nesting failures (CNF) and partial losses (PL), where only one nestling left the nest. Total breeding losses (TBL), were estimated by comparing the estimated total number of eggs laid (TNEL), with the total number of young fledged. In different years CNF varied from 51.8 to 75.7% ( = 61.1, SD = 5.1, n = 25 seasons, CV = 8%) while PL accounted for between 4.3 and 11.8% ( = 8.2, SD = 1.6, n = 25, CV = 19.5 %) of all eggs laid. TBL amounted to between 60.9 and 80% ( = 69.3, SD = 4.3, n = 25, CV = 6.2 %) of TNEL, and was highest at the beginning (February-April) of the breeding season, and at the end (September-October). The losses suffered during incubation ( = 70.6%, SD = 10.3, n = 25, CV = 15%) were much higher than at the nestling stage ( = 29.4%, SD = 10.3, n = 25, CV = 35%). Rooks and Jackdaws were the main nest predators of the Collared Dove population in S3upsk, while Magpies and domestic cats were less effective predators.
