Opportunistic behavioural observation data for the manuscript titled "Behavioural differences between ornamented and unornamented male Red-backed Fairywrens (Malurus melanocephalus) in the nonbreeding season"

This data set consists of the opportunistic behavioural observations described in the manuscript "Behavioural differences between ornamented and unornamented male Red-backed Fairywrens (Malurus melanocephalus) in the nonbreeding season". Each row corresponds to a pairwise behavioural interaction between fairywrens. <br> Observation_ID = unique identifier for each behavioural observation (or row) Date = The date the observation was conducted in YYYY-MM-DD format Year = The year the observation was conducted Time = The time that the observation started in 24-hour format and displayed as "#H #M #S" (e.g., "13H 15M 0S" for 1:15 pm); please note that the time was recorded to the nearest minute, so "#S" is always "0S" Behavior = the social behaviour observed occurring between the sender and receiver fairywren; in this data set, only "Allopreening", "Courtship", and "Chasing" are included <br> Sender_ID = A unique identifier for the fairywren observed sending a behavioural signal (e.g., for courtship, this would be a male performing a courtship display); for allopreening, the distinction between sender and receiver is arbitrary; please note that "Sender_ID" and "Receiver_ID" are equivalent to color band combinations for the fairywrens we observed, but they were generated independently of the "Bird_ID" column from our focal behavioural data set ("RBFW3_Anon_Data_210720.csv"), so the two data sets cannot be linked using these IDs Sender_plumage_category = Categories of plumage scores as per Karubian 2002; the same scoring system is used in this data set as in our focal behavioural data ("RBFW3_Anon_Data_210720.csv") except that Unornamented = DULL, Moulting = MOULT, and Ornamented = BRIGHT Sender_sex = Sex of the bird sending the behavioural signal ("M" for male or "F" for female) Sender_age = Age of the bird sending the behavioural signal obtained through banding records Sender_age_exact = Either "exact" if we were able to determine a sender's precise age or "minimum" if only a minimum estimate (e.g., after second year) was possible <br> Receiver_ID = A unique identifier for the fairywren observed receiving a behavioural signal (e.g., for courtship, this could be a female being courted by a male) Receiver_plumage_category = Categories of plumage scores as per Karubian 2002 Receiver_sex = Sex of the bird receiving the behavioural signal ("M" for male or "F" for female) Receiver_age = Age of the bird receiving the behavioural signal obtained through banding records Receiver_age_exact = Either "exact" if we were able to determine a receiver's precise age or "minimum" if only a minimum estimate (e.g., after second year) was possible <br> Social_mate = Whether or not the sender and receiver observed interacting during the nonbreeding period became social mates during the upcoming breeding season Prev_breeding_group = Whether or not the sender and receiver observed interacting during the nonbreeding season belonged to the same breeding group (social mate, offspring, or related helpers) during the previous breeding season; here, "1" indicates previous breeding group members and "0" indicates that two birds did not belong to the same breeding group previously <br> In this data set, the value "NA" represents missing data.

本数据集包含已发表手稿《非繁殖季节饰羽与非饰羽雄性红背细尾鹩莺（Malurus melanocephalus）行为差异》中记录的机会性行为观测数据。每一行对应细尾鹩莺之间的两两配对行为互动。
Observation_ID：每一项行为观测（即每一行数据）的唯一标识符
Date：观测实施日期，格式为YYYY-MM-DD
Year：观测实施年份
Time：观测开始时间，采用24小时制，格式为“#H #M #S”（例如“13H 15M 0S”对应下午1时15分）；需注意，观测时间精确至分钟，因此“#S”始终为“0S”
Behavior：观测到的发生于信号发送者与接收者细尾鹩莺间的社会行为；本数据集仅涵盖相互理羽（Allopreening）、求偶（Courtship）与追逐（Chasing）三类行为

Sender_ID：执行行为信号发送的细尾鹩莺唯一标识符（例如求偶行为中，完成求偶展示的雄性个体）；对于相互理羽行为，发送者与接收者的区分具有任意性；需注意，“Sender_ID”与“Receiver_ID”对应观测个体的彩色脚环组合，但二者独立于我们的聚焦行为数据集（RBFW3_Anon_Data_210720.csv）中的“Bird_ID”列生成，因此两个数据集无法通过此类标识符实现关联
Sender_plumage_category：依据Karubian 2002年研究设定的羽饰评分类别；本数据集采用与聚焦行为数据集（RBFW3_Anon_Data_210720.csv）一致的评分体系，其中非饰羽对应“DULL”，换羽对应“MOULT”，饰羽对应“BRIGHT”
Sender_sex：执行行为信号发送个体的性别（“M”代表雄性，“F”代表雌性）
Sender_age：通过环志记录获取的行为信号发送个体的年龄
Sender_age_exact：若可确定发送者的精确年龄则取值为“exact”，若仅能获得最小年龄估计值（例如“二龄及以上”）则取值为“minimum”

Receiver_ID：接收行为信号的细尾鹩莺唯一标识符（例如求偶行为中，被雄性求偶的雌性个体）
Receiver_plumage_category：依据Karubian 2002年研究设定的羽饰评分类别
Receiver_sex：接收行为信号个体的性别（“M”代表雄性，“F”代表雌性）
Receiver_age：通过环志记录获取的行为信号接收个体的年龄
Receiver_age_exact：若可确定接收者的精确年龄则取值为“exact”，若仅能获得最小年龄估计值（例如“二龄及以上”）则取值为“minimum”

Social_mate：非繁殖季观测到存在互动的个体，是否在即将到来的繁殖季成为社会配偶
Prev_breeding_group：非繁殖季观测到存在互动的个体，在过往繁殖季是否属于同一繁殖群体（社会配偶、后代或亲缘协助者）；此处“1”代表二者曾属于同一繁殖群体，“0”代表二者此前不属于同一繁殖群体

本数据集内“NA”代表缺失数据。
