The density curve of light signals collected in the reproduction period of six Beijing Swifts. The x axis shows light level (after log transformation), and the y axis shows the percentage of light signals that is in each level. The photo (Photographed by Yu Zhang at Summer Palace, Beijing) shows Beijing Swifts come in and out of a cavity nest, which generates steep change of light level
