Behavioral effects of colorful lights with different spectra on siberian rubythroat Luscinia calliope

Abstract

To investigate the activities of typical night-migrating birds under the light with various spectral compositions during autumn migration, 23 Siberian Rubythroat Luscinia calliope were tested under colorful LED lights with different wavelengths and mixed white at 100 lx. Using behavior response as an indicator, the quantitative relationship between the activity level of test birds and illumination stimulation duration was acquired. It was found that the visible light sensitivity of Siberian Rubythroat was the highest for the 478 nm turquoise and decreased towards the 622 nm red.
