"Landscape photographers rise from their beds several hours before dawn to catch the sun’s first rays paint the sky and clouds with hues of yellow, orange, and red light....  Wildlife photographers also savor the hours immediately following sunrise and preceding sunset for the thick, honey colored light to bathe the animals and birds they seek out with their long lenses. Photographers
don’t call these the "golden hours" for nothing! You may have gathered that if you have a proclivity for sleeping in, you might want to consider a different hobby."
From his book "Essential Light" ~Richard Bernabe
