From: Habitat-dependent changes in vigilance behaviour of Red-crowned Crane influenced by wildlife tourism
Effect of the distance to the nearest road on crane vigilance (a): frequency of vigilance behaviour; (b): percentage of time spending on vigilance behaviour of red-crowned cranes in shorter S. salsa (filled circles), and tall P. australis mosaic wetland habitat (open circles), Yellow River Delta. The blue and red lines represent the linear regression curves between the vigilance and the distance in the shorter S. salsa habitat and tall P. australis mosaic respectively.
