A Morning Pelican

The blue hour  is the period of twilight (in the morning or evening, around the nautical stage) when the Sun is at a significant depth below the horizon and residual, indirect sunlight takes on a predominantly blue shade, which differs from the one visible during most of a clear day, which is caused by Rayleigh scattering.
