The effect of ambient temperature on bird embryonic development: A comparison between uniparental incubating silver-throated tits and biparental incubating black-throated tits

The temperature experienced by avian embryos during development has important impacts on their growth and post-hatching phenotypes. Ambient temperature can directly affect avian nest temperature and indirectly affect it through its impact on parental incubation behaviours. Because the nests of uniparental incubators are usually left unattended more frequently than the nests of biparental incubators whose nests can be attended by another bird when one bird leaves the nest, we predict that the effect of ambient temperature on nest temperature and thus on embryonic development (specifically, incubation period length and hatching success) and post-hatching phenotype (i.e. potential carry-over effect on nestling body mass and condition) should be greater in uniparental incubators than in biparental incubators. To test this prediction, we studied two congeneric species, the biparental incubating black-throated tits (Aegithalos concinnus) and the uniparental incubating silver-throated tits (A...., , , # Data from: The effect of ambient temperature on bird embryonic development: a comparison between uniparental incubating silver-throated tits and biparental incubating black-throated tits

This dataset (Hu_2023_JAB_Tits_data.xlsx) includes the details of the \"nest temperature (°C)\", \"incubation period length (in days)\", \"Hatching success\", and \"nestling body mass (g) & condition\" of the silver-throated tits and black-throated tits, which were collected from 2008 to 2022 (except 2020 when COVID-19 pandemic occurred) in the Dongzhai National Nature Reserve of Henan Province, located in central China (31.95 °N, 114.25 °E). It also includes related data about ambient temperature (°C), clutch size, brood size, etc.

Nest temperature (Sheet 1): Nest temperature data (°C) were recorded by the temperature loggers. We used temperature data loggers to monitor the nest temperature (i.e. the tempe...
