The 'Ugly' Duckling ?

During the recent trip to Florida for Spectrum, Miami, we had the chance to get out to the Keys for a morning shoot.  After the sun had long since risen the waterbirds drew our attention. This "Rag-A-Muffin" was the only one of its kind (presumably a young bird) in amongst the beautiful, pristine white Ibises. The very light sand at Anne's Beach, Islamorada, and the bright light lend themselves naturally to this high-key finish.  The OOF Ibises represent for me a hint of the future elegance and beauty that the "Rag-A-Muffin" will no doubt one day achieve. That he/she also seems to be considering whether there may indeed be a small fish under the plant was a nice addition.  

I have, however, absolutely no idea what species the bird is and would very much appreciate it if somebody with considerably more experience than me could lead me in the right direction.   

Wishing you all a happy, healthy and successful New Year with the best light,

Mark
