What male animal's head appears the same as a child's drawing of the sun?

An ocean, a desert, or just an expanse, the size of the firmament where the stars dance. Swap E for my last, an amphora with a base. 'BL' for my first, loud noise all over the place.

Of light and dark and grey-blue hue, of day yet gone and night in view. I am that which eternal lie, When owls wake and foxes cry. What am I?

My purple hue is a major clue My smile you see but I'm see-thru I put you to sleep, for your dreams I eat I manifest, starting at my feet

I can be big or I can be small, I can be yellow or I can be brown, I have a bill but no money, I have floof but no fur.
