Dataset associated with Hoover et al AUK-19-093 submission: Local conspecific density does not influence reproductive output in a secondary cavity-nesting songbird. Excel CSV with all of the data used in analyses.

Description of variables

YEARS: year
ORDINAL_DATE: number for what day of the year it is with 1 January = 1,……30 December = 365
SITE: acronym for each study site
BOX: unique nest box identifier on each study site
TREAT: designates whether nest box was in a high- or low- nest box density area within each study site
ACTUAL_NO_NEIGHBORS: number of pairs of warblers using a nest box within 200 m of a given pair’s nest box
CLUTCH_SIZE: number of warbler eggs in nest at the onset of incubation
PROWN: number of warbler nestlings once eggs have hatched
PROWF: number of warbler nestlings that fledged out of the nest box
HATCH_SUCCESS: proportion of eggs in the nest that hatched
FLEDG_SUCCESS: proportion of the nestlings that fledged from the nest box
HATCH_SUCCESS2: binary category where “0” indicates there was some, and “1” indicates there was no hatching failure
FLEDG_SUCCESS2: binary category where “0” indicates there was some, and “1” indicates there was no nestling failure (i.e. nestling death)
BHCO_PARASIT2: binary category where “0” indicates no cowbird parasitism, and “1” indicates there was cowbird parasitism
BHCOE: number of cowbird eggs in clutch
BHCOF: number of cowbird nestlings that fledged from the nest
PAIRID: unique number that identifies a male and female warbler that are together at a nest box and this number is the same in a subsequent nesting attempt or year if the same male and female are together again
FEMALE_ID: unique identifier for each female which represents her leg band combination. Each letter represents a band with letters preceding the hyphen being on the right leg and after the hyphen the left leg
FEM_AGE: binary category where “0” indicates a 1-year-old bird and “1” indicates a >1-year-old bird
FEMALE_BREEDING_ATTEMPT: “1” indicates first, “2” indicates second,……..breeding attempt within a given year
SECOND_ATTEMPT: for any female that fledged a brood in a given year, binary category where “0” represents that they did not, and “1” indicates that they did attempt a second brood that year
F_TOT_PROWF: total reproductive output (number of warbler fledglings produced) for a given female in a given year
MALE_ID: unique identifier for each male which represents his leg band combination. Each letter represents a band with letters preceding the hyphen being on the right leg and after the hyphen the left leg
MALE_AGE2: binary category where “0” indicates a 1-year-old bird and “1” indicates a >1-year-old bird
Provisioning_rate: total number of food provisions per nestling per hour by male and female warbler combined
BROOD_MASS: average nestling mass (g) for the brood
BROOD_TARSUS: average nestling tarsus length (mm) for the brood
Brood_condition: unit-less index of nestling condition that uses the residuals of the BROOD_MASS/BROOD_TARSUS relationship

A period (“.”) represents where data were not collected, not available, or because individual nest or female did not qualify for consideration of a category assignment.
An empty cell represents no data available for this particular cell.
