In this repository you can find all the necessary files needed to reproduce the analyses presented in our paper.

• Rcode_Ceuta_PVA.pdf contains the documented code for all analyses, which can be implemented after downloading the datasets provided in the Data_files folder.

• Data_files

  • nest_fate.txt: each row is a single nest. Definitions of variables:
    FirstFound -- Day of the season when nest was found
    LastPresent -- Last day of the season the nest was seen alive
    LastChecked -- Last day of the season the nest was checked
    Fate -- 1 = was seen alive after the 25th day of incubation, 0 = failed before 25th day of incubation
    Freq -- Frequency of nests with these data
    NestAge -- Age of a nest on the first occasion
    Year -- Year that nest was monitored (between 2006 and 2012)
    std_time -- Standardized laying date (early nests are negative, late nests are positive). Note: maximum duration of breeding season is 85 days.

  • chick_data.txt: each row is a single individual. Definitions of variables:
    ch -- capture history of a given chick over the brooding period. 1 = seen, 0 = not seen, . = no survey effort given on that day (i.e. no data)
    Year -- Year the chick was monitored (between 2006 and 2012)
    Day_of_Season -- Day of season the chick hatched

  • fledgling_adult_data.txt: each row is a single individual. Definitions of variables:
    ch -- capture history of a given individual each year between 2006 and 2012. 1 = seen, 0 = not seen
    age -- Adult (A) or fledgling (J). Note: this describes the stage that the individual was initially ringed.

  • fecundity_data.txt: each row is a single male. Definitions of variables:
    Year -- Year of data collection (between 2006 and 2012)
    Bird_ID -- Unique number assigned to each male individual
    Eggs -- number of eggs tended by a given male in a given year
