Detailed nestling growth records with weather conditions in 2017. Nestlings were measured on day 2, 4, 6, 8, 10 and 12. Column headings are as follows: NestlingID=unique ring Canadian Wildlife Service number identifying individual nestlings, NestID=unique code for each nest, HatchSize=number of hatched nestlings, HatchDate=date most of the nestlings hatched (tree swallows typically hatch synchronously) (Julian date), FledgeDate=date the nest fledged (Julian date), FledgeSuccess=0 if this nestling did not fledge, 1 if it did, whyFail=If the nest failed, lists the cause, either “NESTLINGS DIED” if nestlings were found dead in the nest, or “PREDATION” if no nestlings were found, Renest=lists whether nest was a renest or not. All nests used in this analysis were the first nest of the pair, Mass=nestling body mass (g), Tarsus=nestling tarsus length (mm), Wingchord=nestling wing chord (mm), Age=number of days since hatching (e.g., on the hatch date, age=0), MaxTemp3day=mean value of the maximum daily temperatures during the preceding three days (°C), MeanTemp3day=mean value of the mean daily temperatures during the preceding three days (°C), MeanWindspeed3day=Mean value of the mean windspeed (5:30am-8pm) during the preceding three days (m/s), TotalRainFall3day=total rainfall during the preceding three days (mm), ThermoReg=thermoregulatory strategy employed by nestlings of this age (poikilothermic (0-6 days old), intermediate (7-8 days old), or endothermic (9+ days old))
