Avian Eggshell Ultraviolet Reflectance Measurements Across Nest Types, 2024-2025

Spectral reflectance measurements for eggs from three passerine bird species in China. Data includes UV reflectance spectra from 300-700 nm wavelengths collected during breeding seasons from March to August in 2024 and 2025. The dataset was created by Qiqi Liu and published on figshare.

Use Cases

• Testing the UV resistance hypothesis for eggshell coloration based on nest type comparisons
• Testing the egg detectability hypothesis for eggshell coloration based on nest type comparisons
• Comparing spectral reflectance patterns between cavity-nesting and open-nesting bird species
• Analyzing the relationship between egg background color and nesting ecology

Strengths

• Spectral measurements use calibrated equipment (Avaspec-ULS2048×64 spectrophotometer) with integration time set to 200 ms
• Data collection spans two breeding seasons (2024 and 2025) across multiple field sites in China
• Egg reflectance is measured at three points per egg, providing averaged spectra for each sample

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
