Data from: Immune challenge induces terminal investment at an early breeding stage in female zebra finches

all birdsThis file includes all the females that got two injections and was offered a nesting opportunity.ID = Identity of the bird Treatment = Injection with either phosphate buffered saline (PBS) or tetanus-toxoid vaccine Tarsus length = Tarsus length (mm) of the female Body mass = Body mass (g) of the female Scaled index = Condition index of the femaleexp birdsThis file only includes those females that started to produce a clutch. ID = Identity of the bird Treatment = Injection with either phosphate buffered saline (PBS) or tetanus-toxoid vaccine Exp = Control females (1); tetanus-injected females (2) Body mass = Body mass (g) of the female Days to first egg = The time period between first presented with a nest box and nesting material and the production of the first egg by the females. Number of eggs = Clutch size Mean egg mass = Mean egg mass (g) of the eggs in each clutch Total egg mass = Total mass (g) of all eggs in a clutch Mean yolk mass = Mean yolk mass (g) of the eggs in each clutch Mean yolk proportion = Mean proportion of yolk in relation to egg mass in each clutch Arcsin mean yolk prop. = Arcsine transformed mean yolk proportion Diff body Mass = Initial body mass taken on the day of the second injection minus body mass after completion of egg laying. Days btw bm measurements = Number of days between the two body mass measurements Scaled index = Condition index of the female Age = Age of the female; 1 = One year old; 2 = Two years old Tetanus = Tetanus antibody concentrations (mODmin-1) Log (tet) = The logarithm of tetanus antibody concentrationseggsThis file contains all individual eggs Female = Female identity Treatment = Injection with either phosphate buffered saline (PBS) or tetanus-toxoid vaccine Exp = Control females (1); tetanus-injected females (2) Body mass = Body mass (g) of the female Clutch size = Number of eggs in the clutch Egg day = Number of days after the production of the first egg (egg day = 1) that each egg in the clutch were produced. Egg order = The order in which the eggs were produced Rel egg order = The egg order divided by clutch size to adjust egg order for variation in clutch size. Yolk mass = The yolk mass of each individual egg Egg mass = The total mass of each individual egg Albumen mass = The albumen mass of each individual egg Yolk Proportion = The proportion of yolk in relation to egg mass of each individual egg Yolk prop. arcsin = Arcsine transformed yolk proportions of each individual egg Scaled index = Condition index of the female
