Data for: Tracking hybrid viability across life-stages in a natural avian contact zone

Hybrid inviability is an important post-zygotic reproductive barrier between species, but emerging signs of reduced viability can be difficult to study across the lifespan of natural hybrids. We use a combination of long-term monitoring, extra-pair paternity and mitochondrial DNA identification in a natural hybrid zone of Ficedula flycatchers to detect emerging signs of intrinsic hybrid inviability across their entire lifespan. We evaluate possible evidence of Darwin’s corollary to Haldane’s rule, predicting asymmetries in inviability between hybrids resulting from reciprocal crosses, due to incompatible genetic factors with sex-specific inheritance patterns. We found higher hatching failure among mixed-species pairs, possibly indicating early developmental impairments associated with specific parental genetic combinations. Adult hybrids had a higher basal mortality rate than both parental species, and different age-specific mortality trajectories. There were signs of differences in age..., , , # Data for: Tracking hybrid viability across life-stages in a natural avian contact zone [https://doi.org/10.5061/dryad.dz08kps42](https://doi.org/10.5061/dryad.dz08kps42) This is the data accompanying the publication of \"Tracking hybrid across life-stages in a natural avian contact zone\" at Evolution. This record contains all datasets and code necessary to reproduce the analyses, which consists in natural records of life history traits and survival information on wild collared, pied and hybrid flycatchers in the long-term monitoring population of Öland, Sweden. ## Description of the data and file structure All mixed model analyses are described in the R Markdown file \"aalund\_et\_al\_hybrid\_viability\_code.Rmd\", and all Bayasian based BaSTA analyses of survival in the file \"aalund\_et\_al\_hybrid\_viability\_survival\_code.Rmd\". All necessary datasets are named in the Markdown files accordingly to each analysis.
