Title fecundity_data_of_all_females
Downloaded 7 times
Description This file includes fecundity variation of all the females from which 20 high-fecundity and low-fecundity duos were selected (Table S3). The linear mixed models describe variation in female fecundity (i.e. the number of eggs laid per 7-week breeding round; i.e. ‘eggs’; this is ‘estimated fecundity’ before genetic parentage assignment because females were chosen based on that) as a function of female identity (FID), breeding round (first vs. second 7-week period), the number of days females were socially paired (‘dayspaired’), and the exclusiveness of the pair bond (‘Fshare’, with high values reflecting exclusive pairing). The column labelled ‘F’ refers to the inbreeding coefficient of each female.

Title summary_of_20_femaleduos
Downloaded 2 times
Description This file includes all information on the selected 20 duos (Table 1), where ‘duoIDwithin’ is the ID of the female duo within each replicate, and where ‘high’ and ‘low’ always refer to traits of the high-fecundity and low-fecundity females in that duo, respectively. In this file, ‘higheggssoc’ and ‘loweggssoc’ refer to ‘estimated fecundity’ in Table 1, while ‘highGeggs&IF’ and ‘lowGeggs&IF’ mean ‘true fecundity’ in that Table (Table 1). This file also includes all morphological trait values (beak color score: ‘BChigh’, ‘BClow’; mass (g): ‘masshigh’, ’masslow’), age (days) and female responsiveness during the test (‘reshigh’, ‘reslow’) of these 20 duos of females. We also included the inbreeding coefficient of these females (‘F_high’, ‘F_low’).

Title 480_male_10min_tests
Downloaded 4 times
Description This file gives raw data from two-way choice tests: 240 trials of 10min per replicate. After 10min of trial sides are switched, so each ‘Supertest’ of 20 min (see next file #4) consists of two consecutive 10min trials (‘Round’). ‘duoIDwithin’ is the ID of each female duo within replicates. ‘L’ and ‘R’ always refer to the left and right side of the choice chamber, respectively, hence ‘MID’, ‘FID_L’, and ‘FID_R’ are the IDs of the male, the female on the left side, and the female on the right side of the cage. ‘SingL’ is seconds of song to the female on the left. ‘Attention’ is seconds of paying attention without singing to the female and ‘Neutral’ is time not paying attention or in the center. ‘RespL-R’ is the responsiveness of the left minus the right female, ‘PropAtt&SingL’ is the proportion of time paying attention or singing to the left female, ‘FecundFemaleL’ identifies the female on the left as either high or low fecundity; hence, ‘PropAtt&SingHihFec’ is then the attention given to the high-fecundity female. Cases of missing data are explained in ‘Comments’.

Title 227_male_20min_tests
Downloaded 3 times
Description This file gives data for the 227 out of 240 planned ‘Supertests’ of 20min (after excluding 13 tests cancelled because two females died). This is the data for Figure1, Table 2 and Table S4. Here ‘high’ and ‘low’ always refer to traits of the high- and low-fecundity females, respectively, and ‘difference’ always refers to ‘high’ minus ‘low’. Given are the individual IDs, age in days, beak colour (‘BC’), body mass, and responsiveness. ‘Maletest’ refers to a male’s first vs. second choice test, ‘male_choosing_motivation’ is the sum of seconds the male is actively paying attention (theoretical max = 1,200 sec), ‘PrefHighFec’ is then the relative time with the high-fecundity female and ‘correct’ is 1 when ‘PrefHighFec’>0.5. Cases of missing data are explained in ‘comment’.

Title human_rating
Downloaded 5 times
Description This file includes the original data of the ‘Human rating of female fecundity’ experiment. ‘observerID” refers to the 77 participants of the study, ‘order’ refers to the order in which they rated the duos of females, ‘duoIDwithin’ is the ID of each female duo within replicates, and ‘correct’ is the outcome of whether the high-fecundity female was correctly identified by the observer (0=no, 1=yes).

Title nest_building
Downloaded 3 times
Description This file includes original data of the ‘Two-way choice tests: nest-building’ experiment. ‘duoIDwithin’ is the ID of each female duo within replicates, ‘MID’ is the ID of the choosing male, and ‘correct’ is the outcome of whether the male preferred the high-fecundity female (0=no, 1=yes).
