Description
This is a Data package that contains three separate datasets and the analysis code for a manuscript 'Familiarity breeds success: pairs that meet earlier experience increased breeding performance in a wild bird population '. The first Dataset (pairs_data_2007_10) and the second dataset (pairs_data_2011_14) contain the data used to analyse the influence of meeting time of a pair of Great tits (i.e. month in the first dataset, week in the second dataset, when a pair was first detected in a flock together) on different components of breeding success of a pair. The third dataset (meeting_and_divorce) was used to analyse whether meeting time of a pair (in winter prior to the breeding season t) influence the probability of a pair to stay together or separate (divorce) to the following breeding season (t+1).
Notes
This data package contains
1) pair_data_2007_10 dataset (text file)
2) pair_data_2011_14 dataset (text file)
3) meeting_and_divorce dataset (text file)
4) Culina_et_al_ProcB_2020 (R file) - an R code to load the datam conduct the main and supplementary analysis, and to plot main and supplementary Figures
Variable names & meaning
1) Datasets pair_data_2007_10 and pair_data_2011_14
F_ID Unique ID of a female of a pair
M_ID Unique ID of a male of a par
clutchsz Maximal number of eggs in a nest
laydate Date when a first egg was layed in the nest, standardized per year (based on all breeding pairs)
n_chicks Number of hatched young
n_fledged Number of fledged yound
h_succ Hatching success = number of hatched young/ number of eggs
succ_failure Whether a nest field or did not fail to hatch (binary variable)
f_tagged Date when a female was first tagged
m_tagged Date when a male was first tagged
f_first_seen Month (first three winters) or a weekend (last three winters) when a tagged female was first detected at feeders (i.e. female arrival time)
m_first_seen Month (first three winters) or a weekend (last three winters) when a tagged male was first detected at feeders (i.e. male arrival time)
first_seen_together Month (first three winters) or a weekend (last three winters) when a pair was first detected in the same winter foraging flock (i.e. meeting time)
FvsM_arrival Difference between females and males arrival time
met_vs_arrival Difference between meeting time and the arrival time of the pair member who arrived later
year a year of data collection. In the first set of winters this has been coded as e.g. 2007, which refers to winter 2007/08 and breeding season 2008.

50q The value of the 50th percentile of the distribution of the all SRI's (for all birds that later bred) in the month/ weekend when a pair met
75q The value of the 75th percentile of the distribution of the all SRI's (for all birds that later bred) in the month/ weekend when a pair met
2) Dataset: meeting_and_divorce
F_ID Unique ID of a female of a pair
M_ID Unique ID of a male of a par
clutchsz Maximal number of eggs in a nest
laydate Date when a first egg was layed in the nest, standardized per year (based on all breeding pairs)
year a year of data collection. In the first set of winters this has been coded as e.g. 2007, which refers to winter 2007/08 for the meeting time, breeding season 2008 for breeding success, and pair status (faithful or divorced) in 2009 breeding season.
period a period of data collection (2007 to 2010, or 2011 to 2014)
age_f Whether female is a new or old breeder
age_m Whether male is a new or old breeder
status_t+1 Mating status of a pair (divorced or faithful) in the t+1 breeding season
status_bin Mating status as 1 (divorced) or 0 (faithful)
first_seen_together Month (first three winters) or a weekend (last three winters) when a pair was first detected in the same winter foraging flock (i.e. meeting time)
f_first_seen Month (first three winters) or a weekend (last three winters) when a tagged female was first detected at feeders (i.e. female arrival time)
