We really didn't have a winter last year, and it has been about five years since we've seen near to this amount of snow. It is still snowing at the moment, but what is on the ground is already melting. The quail didn't show up for their daily handout until around noon.

For birds, the selective advantage of color seems to outweigh the risks. The color sensitivity of the human eye seems not to be an evolutionary response aimed at reproductive advantage; we are, after all, a rather drab species. Perhaps it is that we are fundamentally omnivores with a need to discern many subtle differences in which color is one important component.
I think some insects and birds may respond to light polarization. Are there creatures that would perceive my house as my camera does when equipped with an infrared filter?
