Possibly an immature green-breasted mango. (But certainly correct me.) They are such shape-changers when they fly. Glorious.
I swung my lens up just in time to catch this low-flying mallard. The sky was so blue and his feathers were so white. (click to enlarge)
Because the insulating properties of their feathers eventually breakdown, Jackass penguins molt once a year and for this 21-day molt cycle they are land-bound. To physically survive, they eat like crazy for 5 weeks before in order to increase fat stores. Psychologically, I am not sure how they prepare for the feather name-calling and ridicule. Penguins can be so cruel… ;-)
Ladies and gentleman, we have lift off! (Much more interesting enlarged so click-away!)
