Abstract: | Fourteen blood profile variables were analysed in 12-day-old nestlings of great tits (Parus major) in the wild. Except for plateletocrit and platelet distribution width, the traits showed a consistent pattern of variation, with significant intra-brood repeatabilities; they were shown to be significant predictors of nestling performance as measured by survival from hatching to fledging. It is concluded that all blood characteristics that show consistent within-brood variation may be useful as indicators of some aspects of nestling condition/health status in wild birds. |
