Application of photographic ‘capture-recapture’ modelling to estimate recruitment and apparent survival in a long-lived territorial raptor

Survival is a life history trait that contributes most to population dynamics in long-lived birds, and the study of individual characteristics is relevant for population conservation. Here we provide information on territorial recruitment and individual replacement in a population of Bonelli’s eagle Aquila fasciata in southeastern Spain based on a long-term photographic capture-recapture 19-year dataset. We also investigated how individual factors such as sex, age, experience and age at first breeding influence the apparent survival of breeding Bonelli’s eagles using Cormack–Jolly–Seber models. An increase in recruitment rates and a decrease in age at first breeding were observed in the breeding population over time. The apparent survival was high, and the reproductive dispersal was very low. The improvement in apparent survival was age-related and higher in females (0.90 for non-adults and 0.92 for adults) than in males (0.87 for non-adults and 0.89 for adults). These findings can be e..., , # Application of photographic ‘capture-recapture’ modelling to estimate recruitment and apparent survival in a long-lived territorial raptor

## bonelli.RData

This data table presents the information of Bonelli's Eagle individuals marked by camera-trapping throughout the study period, including the encounter histories with the basic 0/1 for detected and not detected individuals (variable ch), and different variables related to the individuals for the calculation of survival.

The columns are:

* sex (individual sex)
* ter (territory code)
* ind (individual code)
* birth (year of birth)
* sub (individual adult or non-adult)
* alpha (Age classes (2, 3, 4, 5+) in relation to age at first breeding)
* recr (age of recruitment, years)
* cov1 to cov24 (Territorial experience of individuals each year of the study period; number of consecutive years that an individual has occupied the same territory)
* covC1 to covC24 (squared of ...,
