Storm petrel data sets

Data are organized in three independent files. (1) Breeding_parameters_Espartar_2014_2018.csv records the reproductive parameters (hatching success (HS), fledgling success (FS) and breeding success (BS)) of all accessible nests of storm petrels at s’Espartar islet (Ibiza, Balearic Islands) during breeding seasons 2014 to 2018. First columns correspond to year (2014 to 2018), colony, nest number and zone of the study nests. Zone was coded as “C” = Chambers and “E” = Entrance. Last three columns (F, G and H) gather reproductive parameters HS, FS and BS being 0 if fails and 1 if successful. (2) Data_nestlings_BC_ticks_Espartar_2018.csv contains the state, the number of ticks attached to nestlings, their maximum number, biometric measurements and the estimated age of nestlings of storm petrels at s’Espartar (Ibiza, Balearic Islands) during breeding season in 2018. This file may contain more than one record (line) per individual because some nestlings were inspected multiple times. First column indicates the zone of the nest (“C” = Chambers and “E” = Entrance), next column corresponds to the nest number (= nestling number) followed by state and the state of the next inspection (state_t+1) of the nestling; these columns indicate if nestling is alive or dead. Columns F and G correspond to the number of ticks in each inspection and the maximum number of ticks found among all inspections respectively; last columns are the measurements of the wing length (mm), tarsus (mm), body mass (g) and estimated age of each nestling inspection. (3) Data_Adults_Espartar2018.csv contains the information about breeding adults of storm petrels from the entrance and chambers of the s’Espartar cave (Ibiza, Balearic Islands) during the breeding season in 2018. This file contains one line per individual being the first column the date of inspection, followed by the zone of the nest, the number of nest, and the ring code of the each individual; and the last three columns (E, F, G) correspond to the biometric measurements of tarsus, wing length and body mass (weight). Missing values in all datasets were coded as “NA”.
